Hey everyone, just thought I'd add a walkthrough in case there were any issues or confusion at points in the game.

Walkthrough:

-From the starting room there is only one way forward. If you go past the hallway you can see on the left is a room blocked off by wooden planks. Forward is an inaccessible door and to your right is a hallway.

-If you go down that hallway you will find that the basement door on the left is locked, but the door on the right is not. Going through that there is some ammo on the ground, as well as a shipping invoice. If you proceed forward to the next hallway, straight ahead is a blocked hallway, but to your right is a door leading to an office, in there is the basement key, which you can now use to unlock the door leading to the basement.

-Once you get to the basement your view is blocked by a gas leak which prevents you from moving forward. If you look to the right you can see a set of stairs. Take the stairs and head forward, the door on the left will lead you to an axe. Pick it up and return to the original stairs. 

-Go through the basement doorway and chop the planks off the door to the right and enter, you will see there is a pipe you can interact with, but something is missing. Go back to the hallway where the office is and cut the planks down with your axe (which you can equip from the inventory using TAB). Proceed forward until you reach a warehouse filled with shelves of pallets and crates. In front of you will be a cuboid covered in blood, pick up the wheel sitting on top and return to the room with the pipe.

-Here you can now use the pipe to turn the gas off.

-Proceed to the basement past the gas leak and approach the room in front of you, there is a key lying on the ground, pick it up and turn around. On your left is an office which will give you ammunition as well as a computer containing audio recordings. 

-Exit the office and unlock the door in front of you. Deal with the enemies that arrive as a result, at the first turn you will see a door on your right. This is the door to the chamber, and a door ahead, the bedroom door. If you turn left, there is a hallway with a lot of different rooms, if you explore you'll find extra lore, but otherwise you can proceed to the very end of the hallway and then turn right until you reach a room with red lighting.

-Pick up the ammo and proceed down the ladder. Pick up the chamber key on the floor and make your way through the enemies there. Once you proceed forward you'll see the ladder leading to the bedroom, climb the ladder and pick up the bedroom key to exit the bedroom, afterwards you can now unlock the chamber.

-Move down to the chamber and you will encounter the final boss. (I was not able to finish this part of the game)

Thanks for playing!
