I think there is a timer.

Doors open after some time passes

I got back on my computer after eating dinner and two doors opened

Also some crates have certain items

There is also a puzzle
You have to find some shapes
I got stuck on the triangle

One is in a truck the other is in a building

i found the surface skull

dafuq the triangle at?

triangle is in the sewers shoot the crate outside of the fence, circle lower part of the kitchen counter, square is at the broken down truck. Skulls two in the sewers outta the fences one is in the red room next to the command nest (shoot below the lambda symbol) last one is akward since you need to get into the bathroom, if you can't try shooting the radio or maybe even the headcrab container

i found every item but i dont know what to do with them

I nocliped in to an out of bounds room were the cameras are looking at. i saw a giant donkey picture. then i killed every one there ant red text apierd on my screen that said "why?" i stopped after that because i got scared

im too stupid to get the red room skull.

引用自 Carlos Bird person：

red room next to the command nest (shoot below the lambda symbol)

doing this did nothing for me. so I drove the skull out. i now have all items but i dont know what to do with them. im too stupid
