WARNING! Carry on reading! Or you will die, even if you only looked at the word warning! Once there was a little boy called Joey, he was ten-years-old and he lived in a mental hospital because he posted a crappy copypasta onto a People Playground mod's comment section . He got so bad he went to kill all the staff in the hospital so the Feds decided that best idea was to get rid of him so they set up a special room to kill him, as inhumane as possible. And he sat there in agony for hours until he died. Now every week on the day of his death he returns to the person that reads this letter, on a monday night at 12:00 a.m. He creeps into your room and kills you slowly, by pegging you and watching you bleed to death. Now send this to ten other profiles on this one site, and he will haunt someone else who doesn't. This isn't fake. apparently if u copy and paste this to ten comments in the next ten minutes nothing will happen: sorry man i am not taking the risk

A way to disable the reactor to turn off the power would be interesting

The ICBM is an LGM-25C Titan II ICBM, with a mounted W-53 warhead.

Listen brother, can you refine this database a little so that you can turn off the lights everywhere, it will be very convenient to be honest and put a bark or drink please thank you

there is only one thing i've ever wanted added to this map and that's bathrooms in the bunker

no other map compares to how comfy this one is

Cheese Curds you have to get half life 2 episode 1 and 2 on steam and download them, Gmod will then load their assets into the game
Unequ1vocally 2 Aug, 2023 @ 4:52pm

WalbrechtGaming 23 Jul, 2023 @ 5:29am

I was looking for a map for some scenes I was trying to do. And while this isn't what I was initially after it is something else I was gonna end up needing so nice.

Also to all having errors remember it's not enough to just have the games installed they must be mounted to. It's a quick thing to do and you can do it from in gmod as long as they're installed. Just look up a tutorial.

Is there any previous version of this map like underground_III? I like this map so much and I'm interested in seeing more
Ben 15 Jan, 2022 @ 10:38am 
Map is one of the best, but I still have loads of errors. No missing textures, just errors. I've installed and mounted both HL2 episodes and CSS. If anyone else knows a solution, I'd be happy to hear it.

Will The map function with only Episode 2?
chris 22 Jul, 2021 @ 12:34pm 
To the author who created this, when I launch the map, it gets all laggy. Like I'm getting 2 FPS on a great computer with Multi-Core Rendering enabled with Medium to High settings on, but I still get a lot of lag. Is there, by any chance, a way to fix this? Thank you.
