Batman: Arkham Asylum: Batman: Arkham Asylum 100% Completion Guide

Next up

Intensive Treatment: arrival

From the walk in with the Joker to the first mutated henchman: the Holding Cells fights, Zsasz in Patient Pacification, the Decontamination rescue and every Riddler item these rooms allow without gadgets.

The game opens with Batman walking the Joker into Intensive Treatment, and most of the asylum's staff cross your path on that walk. Once the Joker breaks free you have only the Batarang, the grapnel and Detective Mode; scanning comes later, and riddles only count after the Riddler first calls in the next stretch. Everything listed here needs nothing more. Left for later, when you return with the right gadget: the Riddler's own cell in the Holding Cells, the upper grate and the Maxie Zeus cell in Patient Pacification, the gated office in Decontamination (a tape and a trophy), and the Chronicle and the Iceberg Lounge poster in the Transfer Loop. Decontamination holds this run's first missable trophy: read the warning before you go in.

Leave No Man Behind: save all three men, first try

The next room locks a trophy for this save. In Decontamination two guards and a thug hang from ledges over Joker toxin, and each lets go if you are slow. Go straight to them, in order: the guard on the ledge ahead of you as you come out of the vent, the second guard one level up, then the thug on a lower platform. Detective Mode shows all three. If any of them falls, open the pause menu and choose Restart From Checkpoint at once, before you leave the room; once you are out of Decontamination the room never comes back, and only the Hard run (run 2) gives another chance. The trophy pops when the gas is cleared.

Decontamination: rescue both guards and the thug, clear the toxinQuest stepMissablePoint of no return
Location
Intensive Treatment · Decontamination – Past the window onto the chamber (the guards behind the glass can't be saved), grapple up to a higher ledge and crawl through the vent. Coming out, turn right and pull up the first guard; leap over to the neighbouring platform, then grapple onto the higher one and look left for the second; then glide down to the lower platform ahead for the thug, whom Batman knocks out. In Detective Mode, turn left and hit the fan control panel with a Batarang to blow the gas away.
Why you can lose it
Lost if one of the three men falls into the toxin and you then leave Decontamination: the room is never replayed on this save, so only a new game (the Hard run) gives another try.
Point of no return
Leaving Decontamination for the Transfer Loop (the room change writes a new checkpoint). If one of the two guards or the thug fell into the toxin, Leave No Man Behind is lost on this save; the Hard run is the next chance.
Summary
Pull two guards and a thug up before they fall into the Joker toxin, then clear the gas. Saving all three earns Leave No Man Behind.

Summary

Mutated henchman, Secure Treatment TransferBoss
Location
Intensive Treatment · Secure Treatment Transfer – Go through the painted door. After the cutscene, don't try to beat it: it has no health bar. Keep dodging (double-tap jump with a direction) as it charges and throws bodies; a quick Batarang as it charges stuns it for a few free hits. After a while it drops dead and the trophy pops.

Intensive Treatment to Arkham East

Follow Frank Boles' trail up the Secure Transit shaft, sneak through Cell Block Transfer and the Lobby, take the Riddler's first call, then leave through the Utility Corridor and sweep Arkham East.

This stretch starts after the mutated henchman in Secure Treatment Transfer and ends with the first walk around Arkham East. You have the Batarang, the grapnel and Detective Mode; scanning opens at the first Chronicle of Arkham on the Secure Transit climb. The Riddler's challenge starts when he calls Batman at Frank Boles' body in the Lobby: riddles only count from that call, while the trophies, teeth, tapes and Chronicles you picked up earlier count already. Everything else in Intensive Treatment needs a later visit with gadgets you don't have yet, in sections 11 and 14; the Cell Block Transfer office riddle and Harley's third tape in particular should only be taken in section 11. In Arkham East the gel and Sequencer challenges come in sections 6 and 9, and its Joker teeth only appear later in the story.

Joker teeth: reception deskCollectible

Intensive Treatment · Transfer Loop – From the Secure Treatment Transfer booth, head back north through the Transfer Loop (a few thugs wait at the junction) to the Holding Cells and, in Detective Mode, scan the alcohol spilled from Boles' flask to pick up his trail.

Arkham North and Arkham West

Save the Batmobile and take the Explosive Gel, sweep Arkham North and Arkham West for everything the gel opens, and break into the Medical Facility over its roof.

This stretch runs from the passage out of Arkham East to the roof of the Medical Facility. You arrive with the Batarang, the grapnel and Detective Mode, and pick up the Explosive Gel at the Batmobile; nothing below needs more than that. Arkham North and Arkham West hold many more Riddler challenges behind Security Gates, vent grates, gaps and high weak walls that need later gadgets (the Batclaw, the Cryptographic Sequencer, the Line Launcher and the Ultra Batclaw), and most of their Joker teeth only appear after later story events. The guide takes each one the next time the route passes with what it needs. The two gel spots in Arkham East, under the Botanical Gardens steps and in the courtyard by the Mansion, also wait until the route goes back there.

Defend the Batmobile in Arkham NorthQuest step
Location
Arkham North · Batmobile – From Arkham East, go through the big gate into the short passage to Arkham North. Two armed thugs guard the wrecked ambulance: wait until they turn away, grapple to the ledge above, then drop behind them for silent takedowns.

Arkham Mansion

Back on the surface after the sewers: snipers now hold Arkham North and Arkham East, and the locked-down Mansion is entered through a roof vent with the new Batclaw, up to Dr. Young's Office.

This stretch starts at the Surface Access door into Arkham North and ends in the West Wing Corridor, with Dr. Young's fingerprint trail leading on into the South Corridor. You now have the Batarang, the grapnel, Detective Mode, Explosive Gel and the Batclaw, and the Batclaw opens the vent grates all over the Mansion. Left for later: the Mansion's Cryptographic Sequencer and Ultra Batclaw challenges (the Restricted Files room in the Records Room, which also needs the Line Launcher, and the weak wall on the West Wing Corridor landing), and the security-gated rooms in Arkham East.

Snipers from here on

Armed snipers now stand in the guard towers of Arkham North and Arkham East and on the roof over the Mansion entrance. Turn on Detective Mode to find them, ignore the laser sight, and wait for each one to look away before you grapple up behind him for a silent takedown. Clearing an area's snipers first makes its collectibles safe to pick up.

Joker teeth: Arkham East doorCollectible

Back in the Main Cell Block, a few steps in, Harley switches on the Patient Pacification System and the floor turns deadly. Grapple up to the platforms above at once and fight the convicts there, some with stun batons. Take down first anyone running for the riot gun lockers, and keep the rest from picking up dropped guns. When the fight ends, go into the control room nearby, turn left and hack the panel to shut the floor down.

Location
Penitentiary · Main Cell Block – With the floor safe, get back down (jump over the railing, or hack the panel by the stairs) and take the small passage into the western half of the cell block, after Harley. As you come in, the second cell on your right is covered in calendar pages: scan it.

Guard Room: a timed rescue

Keep heading west to the stairs up to the Guard Room. Inside, Harley has two guards, one of them Louie Green, hanging over electrified pools, and a toxin countdown of about two minutes begins. Order matters: hack a power box first and only then Batarang the rope above that pool, because a guard cut down into live water dies. A death or the clock running out is a Game Over and the scene restarts from the checkpoint, so nothing here is lost for good. The Chronicle below is an extra detour inside the timer: skip it if the clock is tight.

Chronicle of Arkham: Guard Room flooded cornerCollectible
Location
Penitentiary · Guard Room – As you walk in, hack the power box just to your left, then cut that guard down with a Batarang. Before you hack the second box, wade into the water in the left (south-west) corner, gel the weak wall, blow it and scan the Chronicle in the gap; the pools can go live again, so be quick. If the clock forces a restart, leave this unticked and take it when you return to the Guard Room later with the Ultra Batclaw.
Summary
One of the Penitentiary's Chronicles of Arkham, behind a weak wall in the Guard Room's water; it is easiest to reach during the rescue.

Extreme Incarceration and the way to the Gardens

Through Controlled Access to Harley Quinn's fight in Extreme Incarceration, then out of the Penitentiary and across Arkham West and Arkham East to the Botanical Gardens, opening every security gate on the way with the Cryptographic Sequencer.

This stretch starts at the doors from the Main Cell Block into Controlled Access, right after the Guard Room, and ends on the middle floor of the Botanical Glasshouse. You now carry the Batarang, grapnel, Detective Mode, Explosive Gel, the Batclaw and the Cryptographic Sequencer, and with the Sequencer the security gates on the grounds open at last: the walk out takes every gated room in Arkham West and Arkham East that it passes. Two Arkham West items also need the Range Amplifier upgrade. Left for later: the Line Launcher gaps and the high weak walls (Ultra Batclaw) in Arkham West, and the Arkham North security offices, which the route reaches after the Gardens.

When the last inmate is down, Harley is captured in a cutscene. Then switch to Detective Mode and scan her fingerprints: they set the trail to the Botanical Gardens that the rest of this section follows.
Summary

Botanical Gardens

Through the Statue Corridor to the Glasshouse Generator Room to cut the Flooded Corridor's power, round the vents and the Abandoned Chamber, the caged guards in the Aviary, two Titans in the hidden lab and the Line Launcher.

This stretch starts on the second floor of the Botanical Glasshouse and ends in the Titan Production Facility with the Line Launcher in hand. You carry the Batarang, grapnel, Detective Mode, Explosive Gel, the Batclaw and the Cryptographic Sequencer with its Range Amplifier. If you have not been yet, the Glasshouse's north door leads to the Flooded Corridor, where a short Joker scene shows that its water is live; that is why the way on is through the Statue Corridor. Left for later on purpose: the Flooded Corridor trophy and teeth across the big chasm (Line Launcher, next section, on the way to Poison Ivy), the Glasshouse Entrance teeth that appear only after you meet Ivy, the Flooded Corridor teeth that appear after Killer Croc, and the Abandoned Chamber and Titan Production Facility items behind high weak walls (Ultra Batclaw). The Line Launcher also opens a Mansion riddle and a Penitentiary Chronicle; the guide takes those later, because you should not leave the Gardens before you have met Ivy.

The Glasshouse, the Mansion and Intensive Treatment

Line Launcher in hand, cross the Flooded Corridor chasm to talk to Poison Ivy, fight back out of the Gardens, cross the toxic Mansion to Aaron Cash, retake Intensive Treatment from its roof, beat Scarecrow's last nightmare and follow the Secure Transit shafts down toward the Caves.

This stretch starts in the Titan Production Facility with the Line Launcher just picked up and ends in the Secure Transit basement, at the door into the Caves. You have the Batarang, grapnel, Detective Mode, Explosive Gel, Batclaw, Cryptographic Sequencer with the Range Amplifier, and now the Line Launcher, which opens a run of Arkham North items and the way back into Intensive Treatment. Left for later on purpose: the Ultra Batclaw walls (the Abandoned Chamber trophy, the Arkham North cave trophy and others), the last three Flooded Corridor teeth (they only appear later in the story), and the Mansion's Library tape and Records Room files, which this pass over the toxic floor doesn't reach. In Intensive Treatment this route only takes what lies on the way from the roof down to the basement; the rest of the building waits for the island sweep before the finale.

Talk to Ivy before you leave the Gardens

From here, go straight to Ivy's glasshouse and don't leave the Botanical Gardens until you have talked to her. The three Joker teeth at the top of the Glasshouse Entrance stairs only appear after that talk, and one report says that leaving the Gardens first stops them from ever appearing, which would cost the 100% on this file. Break the three teeth on the far side of the chasm before you open Ivy's door, too. The story path already runs this way; just don't turn back early.

The sewers and the Ultra Batclaw

From the Secure Transit basement into Killer Croc's Lair for the spore samples, through the Old Sewer to the Batcave for the antidote and the Ultra Batclaw, then across the sewers to shut down the Titan pumps and fight the Titan in the Pressure Control Junction.

This stretch starts at the door from the Secure Transit basement into Control Room Access and ends in the Pressure Control Junction, at the lift shaft that leads up to Arkham West. You come in with the Batarang, grapnel, Detective Mode, Explosive Gel, Batclaw, Cryptographic Sequencer and Line Launcher; the Ultra Batclaw is built in the Batcave halfway through, and from then on it pulls down the high weak walls and ceilings that the gel can't reach. Every Caves challenge on this route is taken as you pass it. Left for later on purpose: the weak ceiling in Croc's Lair (it is only there after the Poison Ivy fight) and the Ultra Batclaw walls in the Medical Facility, Arkham Mansion and Penitentiary, which this route never enters.

Croc's Lair: walk, never run

Running is loud and brings Croc to you: walk or crouch, and watch the on-screen meter, which shows your noise, the distance to the next goal and turns red when you take a wrong turn. When Croc charges out of the water, one Batarang to his shock collar drives him back; if he reaches you it is a Game Over and you restart from the last checkpoint.

Caves · Croc's Lair – From the channel, Line Launch to the metal balcony on the left, then to the platform on your right, and walk on north until Batman plants Explosive Gel in a cut-scene and drops into the canals. Follow the meter: each spore glows near the ceiling, so knock it down with a Batarang and pick up the sample (five in all). When Croc smashes the wooden planks, keep running without stopping. After the fifth sample a checkpoint comes about 140 m from the exit; sprint back to the first tunnel and, at the closed gate, detonate the gel the moment Croc reaches it.
Summary

Freakshow Rodeo: ride this Titan into the thugs

This is the first Titan the story sets among ordinary thugs, so it is the guide's place for Freakshow Rodeo. The first one, in Intensive Treatment, has no health bar and can't be fought, and the two in the Titan Production Facility come without any thugs to knock over. Here Joker sends waves of thugs alongside it, and a new wave arrives each time you climb on its back. Leave the Titan standing until the thugs are down.

Freakshow RodeoAchievement
Location
Caves · Pressure Control Junction – When Joker locks the junction, ignore the thugs at first and work on the Titan: let it charge, throw a quick Batarang and dodge so it rams a wall or, better, an electrified barrier, then punch it. Once it has lost a health bar and kneels, attack it to climb on and steer it into the thugs. Knocking the same thug down again also counts; keep riding until 10 knockdowns.
Summary
Ride a Titan and knock down 10 thugs with it. It counts in any mode, so a combat challenge map with a Titan works if you miss it here.
PC (Steam)
On Steam the achievement is spelled "Freak Show Rodeo" and its text asks for 5 thugs, not 10.

Return to the Botanical Gardens

Out of the Caves into Arkham West with the Ultra Batclaw, round the island through Arkham North and Arkham East picking up the newly reachable Riddler items, back into the overgrown Botanical Gardens, and the fight in the Elizabeth Arkham Glasshouse.

This stretch starts in the Pressure Control Junction lift shaft, just after the Titan fight, and ends in Arkham North after the Poison Ivy fight. You now have every gadget: Batarang, grapnel, Explosive Gel, Batclaw upgraded to the Ultra Batclaw, Cryptographic Sequencer and Line Launcher. The walk takes the long way round: Arkham West, the tunnel into Arkham North, Arkham North, then Arkham East (with a step back into the Abandoned Tunnel from its far end), which finishes all three outdoor areas apart from one Arkham North trophy you take after the fight. The Ultra Batclaw items inside the buildings (Medical Facility, Penitentiary, Mansion, Intensive Treatment and the Gardens' side rooms) are left for the island sweep that follows.

Snipers and spore pods outside

The island is overgrown now. Spore pods sit along every path and fire glowing orbs at you: Batarang the orbs, then the pod. Snipers are back on the guard towers in all three areas. Before you climb to one, check in Detective Mode which way he faces, and take him from behind or from a hanging ledge.

How the Poison Ivy fight works

The fight has two halves, and the game checkpoints between them. Each half switches between two phases. In the first, roots burst up on the left, in the middle or on the right: keep moving away from them. In the second, dodge the red orbs and throw a quick Batarang (no aiming) whenever Ivy shows herself in the plant. When her health bar is empty, run in and gel her. In the second half, spore-controlled thugs join the root phases: keep to single hits and knock them into the pit.

Island sweep before the finale

With Poison Ivy beaten and every gadget in hand, one loop round the island for the last Riddler challenges: Intensive Treatment, Croc's Lair, the Botanical Gardens, the Mansion, the Medical Facility and the Penitentiary, ending next to the Visitor Center.

This stretch starts in the Arkham North cave beside Intensive Treatment, where the last section ended, and ends in the Penitentiary's Guard Room, a short walk from the Visitor Center. You now carry everything: the Batarang, grapnel, Detective Mode, Explosive Gel, the Ultra Batclaw (it has replaced the Batclaw and does all its jobs), the Cryptographic Sequencer with the Range Amplifier, and the Line Launcher. The game's objective points to the party at the Visitor Center; ignore it until this loop is done. Nothing here is lost if you skip it: free roam carries on after the ending, and every Riddler challenge can still be taken then. Doing it now keeps Perfect Knight on track and means the finale is the last thing you do. The loop visits each building once, in an order that never doubles back across the island. Only one Riddler item is left after it: the 24th Chronicle, which appears once the other 23 are scanned and starts the next section.

Check what is left before you leave each place

Every location's Secrets Map marks its remaining Riddler items on the pause map, and the Riddler challenge list shows each location's count. Joker teeth are the exception: the map never shows them. Before you leave a building, check its count against the items below; anything an earlier section left unticked can be picked up on the same visit. That includes the items that needed the Range Amplifier if you bought it late: the gated balcony room over the Penitentiary entrance, the Glasshouse Generator Room trophy and Secrets Map, the Arkham North front-gate trophy and the Intensive Treatment tape behind a powered gate.

The finale

The last Chronicle in the Security Control Room, then the Joker's party at the Visitor Center (Party Pooper and Freeflow Combo 40 in one fight), the Throne Room, the final fight on the Penitentiary Roof and free roam after the credits.

By now the island sweep is done and you carry every gadget: the Ultra Batclaw, Explosive Gel, the Cryptographic Sequencer and the Line Launcher. No Riddler item is left for later: the sweep should have finished them, and anything missed can still be done in free roam after the credits. One thing is lost for good on this save: the Party Pooper trophy, decided by the fight outside and in the hallway of the Visitor Center. Take the last Chronicle first, while you are still in the Penitentiary and the party waits.

Party Pooper: all 20 party thugs before the Visitor Room

The door at the end of the Visitor Center hallway leads into the Visitor Room, and from there the game runs on to the ending with no way back out. Before you go through it, knock out all 20 party thugs: the 4 outside the Visitor Center front and the 16 in the hallway behind the red side entrance. They never strike first, so you have to start every fight. Down the outside four before you step into the hallway, as the way back out may close behind you. This is also the moment to finish anything else you want before the ending; Riddler challenges are not lost, because free roam returns after the credits. If a thug is left standing, pause and Restart From Checkpoint while you are still outside or in the hallway: it takes you back to just outside the Penitentiary. Once you are in the Visitor Room, only the Hard run (run 2) gives another chance.

Location
Arkham West · Visitor Center – Back out of the Penitentiary, go to the Visitor Center front, the doors painted with the Joker's face, and take on the 4 thugs standing there. With all four down, go in by the smaller red-painted side entrance and knock out all 16 thugs in the hallway behind it before you touch the door at its far end. Read the next item before you go in: the hallway fight is your best Freeflow Combo 40 chance.
Why you can lose it
Lost once you go through the hallway's far door into the Visitor Room with any of the 20 still standing: there is no way back out until the credits, and the thugs are gone afterwards. Only the Hard run gives another try.
Point of no return
Going in by the red side entrance into the Visitor Center hallway (the 4 thugs outside may be out of reach once you are inside), and at the latest through the door at the far end of the hallway into the Visitor Room. From there the story runs on to the ending with no way back out, the checkpoint moves past the party, and the party thugs are gone after the credits. Party Pooper is then lost on this save; the Hard run is the next chance.

A missable trophy for knocking out every thug at the Joker's party, 4 outside the Visitor Center and 16 in its hallway, before going into the Visitor Room.

The roof fight, round by round

Each of the three rounds runs the same way. Beat every thug the Joker sends and keep clear of the wind-up teeth, which blow about a second after their laugh (let them go off near thugs to stun them). Only when no thug and no tooth is left and he turns away to pose for the helicopter, fire the Ultra Batclaw at his back and mash the button to pull him off his balcony; a thug or a tooth breaking the pull means another, smaller wave first. Round two adds thugs with knives and stun batons. Round three adds a gun locker right under his balcony (keep the thugs from opening it, and keep any gun they get on the floor) and electrified barriers beside it, which you can knock thugs into. If he stands still and the round won't move on, or the camera drifts out of the arena, pause and Restart From Checkpoint.

Afterwards you are back on the island in free roam with every gadget: few enemies remain, some of Ivy's overgrowth is still there, and any Riddler challenge left open can still be finished.
Summary
The end of run 1's story. The save then carries on in free roam on Arkham Island, with every gadget.

Challenge maps

Back on the run-1 save after the credits: all 48 medals on the 16 Combat and Predator challenge maps, the three challenge trophies, the optional downloadable maps and, last, Perfect Knight.

Load the run-1 save once the credits have rolled. By now it holds every gadget, all 20 WayneTech upgrades and all 240 Riddler challenges, and each Riddler trophy below has already opened its map. The 16 base maps (four Combat, four Predator, plus an Extreme version of each) carry three medals apiece: all 48 are needed for 100%. Challenge maps always play at Normal difficulty, whatever the campaign was set to. The order here is the trophy warm-ups first, then the base Combat maps, the Extreme Combat maps, the base Predator maps and the Extreme Predator maps; the downloadable maps come after them and are optional. The maps where you play as the Joker are not covered.

Keep the medals on the run-1 save

The story, the 240 Riddler challenges and all 48 medals have to sit on one save for the 100% count. Do every map on the run-1 save, and start the Hard run (run 2) in a different slot; nothing on this page can be lost, so the two runs can be played in either order.

Missed a combat trophy in the story?

The trophies whose text says "any play mode" (the Freeflow Combo trophies, Rope-A-Dope-A-Dope, Mano-A-Mano, Catch! and Freakshow Rodeo) also count on challenge maps. Rumble in the Jungle brings Titans for the Titan ones, and any Predator map works for an Inverted Takedown string-up.

Combat maps: how the score builds

Each Combat map is four rounds, and the medals go by total score. A long combo multiplier is worth more than early finishers, so save the takedown finisher for knife and stun-baton thugs. Mix moves within one combo: the end-of-round bonus grows with every different move used, up to all nine. Bonuses also pay for a round without damage, a whole round in one combo and four rounds without damage. A combo breaks on a hit taken, a move that hits nothing or a pause of about a second; vaulting over a thug never breaks it. Knives need a cape stun or a finisher, not a plain strike; vault behind stun batons. Weapons dropped in one round stay on the floor for the next.

Flawless Freeflow Fighter: Intensive Treatment without a hitAchievement
Location
Intensive Treatment · Challenge Mode – Open Challenge Mode on the run-1 save and start Intensive Treatment, the first Combat map; it opened when you destroyed the fifth set of Joker teeth ("Joker teeth: Eddie Burlow's hall", Intensive Treatment: arrival). Get through all four rounds without being hit: the combo may drop, so counter everything and vault over thugs when they crowd you.
Summary
A trophy for clearing all four rounds of one Combat map without taking damage. Intensive Treatment, the easiest map, is the place for it.

Intensive Treatment · Challenge Mode – Same map as the trophy above, opened by "Joker teeth: Eddie Burlow's hall" (Intensive Treatment: arrival). Medals at 6,000, 12,000 and 18,000 points; a run that earned Flawless Freeflow Fighter often reaches all three, so check the map's medal count before playing again.

The easiest Combat map: four rounds of unarmed thugs and a few with pipes. Its three medals count toward the 48 needed for 100%.

Freeflow Perfection: the nine moves

All nine have to land in one combo, in any order, with no hit taken and no miss: a plain strike; a Batclaw pull and then a strike on the thug as he comes in; a counter; a vault over a thug; a cape stun; the Special Combo Throw; the Special Combo Takedown; a quick Batarang throw (Combo Batarang); and a ground takedown, kept for the last thug standing. Both finishers need the combo built up, so you build it twice in the same chain; Special Combo Boost lowers the count needed.

Intensive Treatment · Challenge Mode – Stay on Intensive Treatment: round 3, with its pipe thugs, gives the most room to work through the list in the tip above. Sewer Bat, the next map, works too if you would rather do it there while chasing medals.

Run 2: Hard

A second, story-only playthrough on a new save at Hard for the last difficulty trophy, with a Hard note for every boss and second chances at the two missable trophies if run 1 lost them.

Run 1 earned everything except the Hard difficulty trophy. This run is the story again on a fresh save, nothing else: no Riddler hunt, no challenge maps. On Hard the counter warning over an attacking enemy is gone and every hit you take hurts more, so you counter by reading each enemy's wind-up. The route is run 1's story route: each step below names the run 1 section to follow, and you can skip every Riddler and optional item listed there. Your gadgets come back in the same story order as in run 1. Keep the run 1 save: the challenge maps and Perfect Knight belong to it, and those maps always play at Normal, so you can switch back to them whenever Hard wears you down.

Location
Intensive Treatment · Entrance and Intensive Treatment Lobby – From the main menu, start a new game on a save file other than run 1's and choose Hard.

Pick up some XP on the way

Upgrades come from XP on this save too, and the Armor upgrades matter most on Hard. Solving Riddler challenges you happen to pass earns XP quickly and may restore some health as well. Buying an Armor upgrade may also refill your health, so a level-up saved for a hard fight can work as a spare health bar.

Leave No Man Behind, second chance: skip if run 1 has it

Only if Leave No Man Behind did not unlock in run 1. The Decontamination rescue in the next step works exactly as before: two guards and a thug hang over the Joker toxin, and all three must be pulled up. If one falls, pause and Restart From Checkpoint before you leave the room; once you are out of Decontamination the chance is gone on this save too, and there is no third run in this guide.

Location
Intensive Treatment · Decontamination – Reached as in run 1, in "Intensive Treatment: arrival", after Zsasz and the vents. Coming out of the vent, pull up the guard ahead of you, then the second guard one level up, then glide down for the thug on the lower platform; Detective Mode shows all three. Clear the gas with a Batarang to the fan control panel. When Leave No Man Behind pops here, also tick run 1's Decontamination step, so your 100% count is complete.
Why you can lose it
Lost if one of the three falls into the toxin and you then leave Decontamination: the room never comes back on this save, and this is the last run the guide plans.
Point of no return
Leaving Decontamination for the Transfer Loop on the Hard save. If any of the three men fell, Leave No Man Behind is lost on this save as well.
Summary
The Decontamination rescue again, for the trophy run 1 may have missed. Skip this step if Leave No Man Behind already unlocked.

Croc's Lair on Hard

Walk or crouch, never run: the noise meter also shows how close he is and turns red when you head the wrong way. When he bursts out of the water, one Batarang to his shock collar drives him back; if he reaches you it is a Game Over. Knock each glowing spore down with a Batarang, then pick it up (five in all), and keep running without a pause whenever the planks break under you.

Each half of the fight swaps between two phases. First, keep moving away from the roots that burst up on the left, in the middle or on the right; then, when she opens the plant, dodge her orbs and hit her with a quick Batarang. With her bar empty, gel her. The second half adds spore-controlled guards during the root phase: each goes down in one hit, so knock them into the pit.

Party Pooper, second chance: skip if run 1 has it

Only if Party Pooper did not unlock in run 1. After Ivy the game sends you to the Visitor Center in Arkham West. Knock out all 20 party thugs, the 4 outside the front and the 16 in the hallway behind the red side entrance, before you go through the hallway's far door into the Visitor Room. They never attack first. Down the outside four before stepping into the hallway. If one is left standing, Restart From Checkpoint while you are still outside or in the hallway; once in the Visitor Room the story runs to the ending and the chance is gone.

Location
Arkham West · Visitor Center – From Arkham North, where the Ivy fight ends, follow the objective to the Visitor Center and play the party as in run 1, in "The finale" (this run skips that section's Chronicle). Start on the 4 thugs at the Joker-painted front doors, then go in by the smaller red side entrance and drop all 16 in the hallway before you touch the far door. When Party Pooper pops here, also tick run 1's Party Pooper item.
Why you can lose it
Lost once you go through the hallway's far door into the Visitor Room with any of the 20 still standing: there is no way back out before the credits, and this is the last run the guide plans.
Point of no return
Going in by the red side entrance into the Visitor Center hallway on the Hard save (the 4 thugs outside may be out of reach once you are inside), and at the latest through the door into the Visitor Room. The story then runs to the ending; any party thug still standing means Party Pooper is lost on this save as well.
Summary
The Joker's party again, for the trophy run 1 may have missed. Skip this step if Party Pooper already unlocked.

Before you leave for the party, copy the save file (.sgd) somewhere safe as a way back if the fight goes wrong after the checkpoint has moved on.

The Throne Room and the roof on Hard

Throne Room: thugs keep coming in a small room; dodge the two Titans first and stay near thugs so the charges hit them, and Batarang a Titan only while it runs at you. One Titan down and the rest is much easier. Roof, every round: clear every thug and keep away from the wind-up teeth, which go off about a second after their laugh. Only when nothing is left and he turns to the helicopter, pull him down with the Ultra Batclaw and hit him. If he freezes or the camera drifts out of the arena, Restart From Checkpoint.

Trophy and achievement table

Every trophy and achievement with the item that earns it on this route, how the lists differ between platforms, and the PlayStation platinum.

There are 47 trophies and achievements, and PlayStation adds a platinum for earning them all. Two can be lost on a save: Leave No Man Behind at the very start and Party Pooper before the finale (both have warnings where they happen, and the Hard run repeats them as a backup). One Riddler riddle can be lost too, the body in Dr. Young's office on your first Mansion visit; without it the 240 cannot be finished on that save, which costs Crack The E Nigma and Perfect Knight. The difficulty trophies stack, so finishing on Hard also gives the Easy and Normal ones. Rows whose item names a late story moment are hidden until you reveal them.

How the lists differ by platform
PlatformListNotes
PlayStation 4 (Return to Arkham)48 trophies: 1 platinum, 1 gold, 18 silver, 28 bronzeThe platinum unlocks once the other 47 are earned.
Steam (Game of the Year Edition)47 achievementsThe same 47 as PlayStation without the platinum; none are hidden. A few names are spelled differently, for example "Freak Show Rodeo", and its text asks for fewer thugs (this guide asks for 10 everywhere).
Xbox One (Return to Arkham)47 achievements, 1,000 GamerscoreThe same 47 names.
PlayStation 3 and Xbox 360 (2009)48 trophies / 47 achievementsThe original releases have lists of their own with the same names and grades; this guide follows the Return to Arkham and Game of the Year Edition versions.
Platinum TrophyAchievement
Location
Anywhere – There is nowhere to go: it pops the moment the last other trophy does, which on this route is usually Biggest Bang at the end of the Hard run or Perfect Knight after the challenge maps. If it doesn't appear, open the trophy list, find the one still locked and look it up in the table above.

Summary
The PlayStation platinum, which unlocks by itself once the other 47 trophies are yours.
PC (Steam), Xbox One
Steam and Xbox One have no platinum: their lists end at the same 47 achievements. It is optional and does not count toward this guide's 100%.

About this guide

Two playthroughs. Run 1 on Normal does the story, all 240 Riddler challenges, every upgrade and the 48 challenge-map medals on one save. Run 2 is a story-only run on Hard, where the counter prompts are gone; finishing on Hard also awards the easier difficulty trophies.
