The bonus modes and Extras purchases that sit outside the walk. None of them counts toward 100%.
This appendix covers what the game offers beyond the story. None of it has a trophy or moves your percentage, so take only what you enjoy. Several extras are bought in Extras with points, which you earn by finding collectibles, earning trophies and finishing the story on higher difficulties. The modes that do carry trophies (Grounded, Permadeath, Chronological and No Return) are covered in the run and No Return sections.
Lost LevelsOther
Location
Main menu · Lost Levels – Pick Lost Levels from the main menu; no unlock is needed. Each level is an unfinished early version, and you start the commentary by interacting with objects set around it. There's nothing to collect, and any skins you own can be worn.
Summary
Three playable levels cut early in development, with developer commentary. No trophy, and it doesn't count toward 100%.
Main menu · Guitar Free Play – Choose Guitar Free Play from the main menu. The mode is open from the start, but some instruments unlock only as you progress through the story. Play as Ellie, Joel or the composer Gustavo Santaolalla, switch between guitar, banjo, steel resonator and other instruments, add effects pedals and pick a backdrop taken from places in the story.
Summary
The story's guitar minigame as a mode of its own. No trophy, and it doesn't count toward 100%.
Main menu · New Game – It unlocks through story progress, so it's sure to be there once you've finished the story. Turn it on as you start a New Game or New Game+; a run already under way or a chapter picked from the menu can't use it. You can time the whole game or either half of the story. The clock stops during cutscenes, modifiers are allowed but mark the run, and your times are listed under Extras in Speedrun Recap.
Summary
An on-screen timer for timed runs, with your records kept. No trophy, and it doesn't count toward 100%.
Main menu · Extras – Finish the story, then open Extras from the main menu and spend points to unlock them. The modifiers come in three groups: Mirror (such as Mirror World), Cheats (such as Infinite Ammo, One Shot and Touch of Death) and Audio (8-bit, 4-bit, Helium and Xenon). The render modes, about 30 of them, change only how the picture looks. Grounded and Permadeath switch some modifiers off, so they can't help with those trophies.
Main menu · Extras – Open Extras from the main menu to spend your points. There are skins for the playable characters of the story and for their weapons, and you can wear them in the story, in Lost Levels and in No Return. Skins for the No Return characters come from that mode's challenges instead, and Chronological mode unlocks two more of them.
Summary
New outfits and weapon looks, paid for with the points you earn by playing. No trophy, and they don't count toward 100%.
