Walkthrough
  1. 1
    Head northwest in the Forest to a gate near a large spider egg. Use the key to enter.
  2. 2
    Defeat the Broodmother and smaller spiders. Weapons like the Submachine Gun and Riot Shotgun are effective. Avoid its tentacles. This battle grants the "That’s a hell of a spider" achievement.
  3. 3
    After the battle, head north to find a bunker entrance leading to tunnels.
  4. 4
    Follow the tunnels, fighting spiders and tentacle men. Locate a map, a TV save point, and a campfire.
  5. 5
    At a path split, head northwest, defeat enemies, and find a locked door. Continue west to find another map and lootable containers.
  6. 6
    Head southwest, burning an obstacle with a Molotov Cocktail or explosives.
  7. 7
    Follow the path east, crouch under supports, and break another obstacle.
  8. 8
    Head southeast, then east through an electrified area, defeating a large enemy. Find a first-aid kit and the Minecart Brake Lever.
  9. 9
    Turn off the switch to make the electrified zone safe. Loot two boxes protected by a hazmat enemy and a tentacle man.
  10. 10
    Return to a previous path split and head west. Defeat a large enemy and use the Minecart Brake Lever on a broken mine cart. Use Fuel to activate it.
  11. 11
    This activates a door near the cart. Go through to find a Workbench, a TV save point, and containers.
  12. 12
    Use the activated cart to move to a previous area and go through the newly unlocked door with a green light.
  13. 13
    Follow the path, fighting large spiders. At a split, going northwest leads to a dead end with lootable containers.
  14. 14
    Head northeast, defeat a large enemy, and find a first-aid kit.
  15. 15
    Continue along the path, looting a box. At a split, deal with tentacle men to the southeast and a large spider to the southwest before looting the box.
  16. 16
    Follow the southern paths which merge. Defeat large spiders and find a trapdoor. Loot a box north of it. Open a shortcut northwest of the trapdoor.
  17. 17
    Go through the trapdoor and follow the path southeast. Defeat a large spider and find a first-aid kit.
  18. 18
    At a path split, head east to find a TV save point, a Crank on a machine, and a lootable box.
  19. 19
    Return to the split and head west, crouching under supports. Find two boxes near a ladder (a shortcut to the tunnel entrance).
  20. 20
    Go back up the ladder you came down from. Head northeast and find another ladder.
  21. 21
    Climb the ladder and defeat a tentacle man. Loot a box southwest of the trapdoor.
  22. 22
    Head south of the trapdoor, defeat a large spider, and find a box.
  23. 23
    Head east of the trapdoor, defeat a tentacle man, and follow the path. At a split, take the north path, defeat a large enemy, and loot boxes and crates. Use the Crank on the machine to open doors below.
  24. 24
    Return to the trapdoor and go down. Head northeast and northwest, then northeast through the opened door. Climb the ladder at the end to exit the tunnels.
  25. 25
    Head northwest to the Druid’s Hut. Loot a box to the left and use the Workbench to the right.
  26. 26
    Inside the Hut, find a box, a Stove, and another box. Read the note on the north table.
  27. 27
    In the next room, find a TV save point and a bed. A trapdoor with a button is present but inaccessible for now.
