I apologize in advance for grammar errors!

Troubles with finding a key to emergency pumps

The most common thing here is searching for a key to emergency pumps. It is located in flooded sector 6, in a dead-end, under.

While you just entered flooded sector 6 there are 2 ways: Straight and down. Go down. You will locate another room, but there’s going to be nothing. Keep going down and to the right, there will be a key laying on the ground. Then you should return to pumps.


Spoiler: this is going to be the most interesting part of your game.

Level 4. Day 91

Finding a key to the beams control room

First: go all the way up, and move to the right. You will see a half-opened door here. Crawl and you will see a crank (be careful, as there usually cocoons spawn in) You got the crank? Good. There are elevators which are very very close to the half-opened room (which you are currently in) go up here. Open the door with a crank and get a fuse. Go back to another elevator.

Short instructions

-You got a fuse


-Find another elevator near you got up to this floor

-To the left, there is a fuse box, insert a fuse here.

-Go up again, and move to the left. You’ll see a storage room and elevator near it. In the storage room, there are ammo and medkits, you can take them if you want. Go up on a elevator, to the left, there are going to be a small room, with a steel cabinet and a button. Press the button and get the key.

Congrats! You got the key. Run back to the beams control room.

Most common problem: using a remote control cage

You need to go to sector 8. But, there are a pit and metal cage.

-Select engineer and get close to the cage as possible

-Instructions will show up.


If you really don’t know, just search above.


So, you found a pa*sage, but, where is the entrance?

You need to use terra scanner and explosive, twice. These place are pretty obvious, and don’t forget to use terra scanner.


You are on a very limited time, you need to deliver cubes to a stabiliser pit which located in Sector 7, at the very beginning near elevator. You should’ve notice it, as it’s an hazardous s*ripes and very deep pit. And pretty close to a big pit with metal cage. You need to load 3 cubes and drop them into the pit.
