Run 1: Krasnogorje and the Underground Tunnel

Down the short cliff into Krasnogorje, up the mountain to the ruins for Key B and the view over Groznyj Grad, then through the red door into the tunnel and a boss fight.

This stretch starts at the top of the long ladder out of the Krasnogorje Tunnel. A short cliff there closes every area behind you, so the first callout is a checklist. Then it climbs Krasnogorje: the Mountain Base with its vultures and scorpions, the Mountainside armory with the RPG-7, the trenches of the Mountaintop and the ruins at the summit, where a meeting hands over Key B and a long scene looks out over Groznyj Grad (the first of the six hidden views). Key B opens a red door into the tunnel, and at the bottom of its ladder a boss waits. Carry the Mk22, the SVD, the Mosin-Nagant, the Thermal Goggles and a Cardboard Box; the Animals camo suits the bare slopes. The rule stays the same: no kills and no alerts. The air up here is thin, so stamina drains faster than usual: eat when it runs low. Nothing here waits for later: Krasnogorje closes at the tunnel ladder, and the fight's reward must be picked up before the ladder out of the tunnel.

Before the short cliff: everything from the caves to Sokrovenno

Right after the long ladder, Krasnogorje Mountain Base starts with a short cliff. Once you drop down it, none of the areas behind you can be reached again in this run: the caves, Ponizovje, Graniny Gorki, Svyatogornyj, Sokrovenno and the Krasnogorje Tunnel. Check every row below first; save on 140.96 at the top of the ladder once you are sure. Chyornyj Prud: Food: Milk Snake; Food: Coral Snake (easily mistaken for it); Food: Poison Dart Frog. Food whose last spot is behind this cliff: Food: European Rabbit; Food: Baltic Hornet's Nest; Food: Yabloko Moloko (still in Sokrovenno and Svyatogornyj if missed). Chyornaya Peschera: Food: Taiwanese Cobra; Kerotan: Chyornaya Peschera Entrance 1. Ponizovje: Kerotan: Ponizovje South 1; Kerotan: Ponizovje West 1; Kerotan: Ponizovje Warehouse Exterior 1; Face Paint: Desert; Kerotan: Ponizovje Warehouse 1. Graniny Gorki South: Food: Fly Agaric; Kerotan: Graniny Gorki South 1. Graniny Gorki Lab: Food: Red Avadavat; Kerotan: Graniny Gorki Outside Walls 1; Kerotan: Graniny Gorki Inside Walls 1; Kerotan: Graniny Gorki Lab 1F 1; Kerotan: Graniny Gorki Lab B1 East 1; Kerotan: Graniny Gorki Lab B1 West 1. Svyatogornyj: Kerotan: Svyatogornyj South 1; Food: Spatsa; Food: Ural Luminescent; Kerotan: Svyatogornyj West 1; Kerotan: Svyatogornyj East 1. Sokrovenno: Kerotan: Sokrovenno South 1; Kerotan: Sokrovenno West 1; Kerotan: Sokrovenno North 1. Krasnogorje Tunnel: Kerotan: Krasnogorje Tunnel 1. Two more checks: a live Tsuchinoko must already be in your bag, since every known trap spot lies behind this cliff, and the Water face paint from the Ponizovje South river must be in your face paint list. Anything missed comes back only in a later run that passes this way, and run 2 is a lean Extreme run with no time for it.

Area: Krasnogorje Mountain BaseArea
Location
Krasnogorje · Krasnogorje Mountain Base – At the top of the long ladder from the Krasnogorje Tunnel, walk ahead and drop down the short cliff; there is no climbing back. Go forward and round the corner to the right into the open slopes. Crawl with a high camo index (the Animals camo suits this ground). A rock in the middle of the area holds Mk22 ammo if you are low.
Requires
Summary
Bare slopes at the foot of the mountain, with vultures on the cliff edges. The thin air drains stamina faster than in the forest.

Food: White-Rumped VultureConsumableMissablePoint of no return
Location
Krasnogorje · Krasnogorje Mountain Base – Save first; if anyone is hit, reload. Do this before anything else in the area, so a reload costs nothing. Vultures perch on the left-hand cliff edge here or circle overhead. Pick one well away from any guard, kill it with a lethal gun such as the SVD and walk over to pick it up. If none show up, they also perch on the cliff edges of the Mountainside and the Mountaintop. Don't leave a guard asleep where vultures land: one feeding on a sleeping guard may count as a kill.
Why you can lose it
Krasnogorje closes for this run once you climb down the ladder in the tunnel beyond the red door. Take it on this pass. Its only spots are the three Krasnogorje slopes.
Point of no return
Climbing down the ladder below the red guard rails in the tunnel. The fight starts at the bottom, and Krasnogorje is closed for the rest of this run.
Requires
Summary
BIRD B, one of the 48 plant and animal types for King of the Jungle and the last of the five birds for A Bird in the Hand. It is too big to carry off alive, so this one has to be killed; animals don't count as kills.

If it doesn't, check the food list: a missing Magpie or Sunda Whistling-Thrush still turns up in the Zaozyorje woods near the end of the run, and the trophy pops there; the Parrot and the Red Avadavat can't be found in the wild again.

Food: Emperor ScorpionConsumableMissablePoint of no return
Location
Krasnogorje · Krasnogorje Mountain Base – Emperor Scorpions crawl on the ground of these slopes, near the vultures' cliff edge. They are small: put on the Thermal Goggles to find one. It can sting, so dart it with the Mk22 before you pick it up. More crawl on the Mountainside and in the ruins at the top. If Food: Thai Cobra is still missing from the caves, one crawls on the ground just past the first corner after the drop: take it the same way.
Why you can lose it
Krasnogorje closes for this run once you climb down the ladder in the tunnel beyond the red door. Take it on this pass.

Climbing down the ladder below the red guard rails in the tunnel. The fight starts at the bottom, and Krasnogorje is closed for the rest of this run.

Save before you go upstairs: the first hidden view

Going upstairs starts a meeting and then a long scene looking out over Groznyj Grad. That scene holds Hidden view: Krasnogorje Mountaintop, the first of the six hidden first-person views for Snake Eyes, and it plays only once. Save on 140.96 before the stairs. You may skip the meeting's talk, but skip nothing once the view over the base begins. The cue: when The Boss turns to leave, saying she is off to fetch the Davy Crockett, hold the first-person button (R1, RB on Xbox) until she has ridden away. If the view is missed, reload that save and watch again; the reload puts you back at the door, so take this area's Kerotan and any scorpion after the scene, not before.

Krasnogorje · Krasnogorje Mountaintop: Behind Ruins – Watch the scene over Groznyj Grad without skipping. When The Boss arrives and then turns to leave, saying she is off to fetch the Davy Crockett, hold the right shoulder button (R1 on PlayStation, RB on Xbox) and keep it held until she has ridden away: the view switches to Snake's eyes. Holding it at other quiet moments of these scenes costs nothing and may catch another view.
Why you can lose it
The overlook scene plays once. If the view was missed, reload the save from before the stairs and watch it again before you carry on.
Point of no return

Before the red door: finish Krasnogorje

Beyond the red door, stairs lead down to a ladder into the tunnel, and once you climb down it there is no way back up: the rest of Krasnogorje is gone for this run. Check these rows first.

Win The Fury's fight on stamina

The fight ends the moment either of his bars runs out. Only a stamina win counts for Stamina Kill: The Fury and drops Camo: Fire, one of the uniforms for Fashionista; a lethal finish loses them for this run. Kerotan: Groznyj Grad Underground Tunnel 1 also has to be hit before he goes down. Save on 140.96 at the rails before the ladder. A death or a reload in the tunnel can undo the frog: after one, look for it on the red pipes again and hit it if it is back.
