About Underground Survival
one of my first games that were mostly free modeled and buggy. Check for the version of the server on the top left of the screen in game! TIP: Points don't go to anyone if multiple players are shooting one enemy, so you should explore around more of the base and find enemies by yourself to get points! V9.9: Added more damage to the Starter Pistol, Added more damage to Upgraded Pistol, increased price of Knife in the shop, added Health labels to The Rake and Sonic.exe Press Q to open, and close the shop! ADDED MICHAEL MYERS, CHUCKY, AND JEFF THE KILLER! Start opening more doors and going deeper into the base to find them ;) TIP: Close doors behind you to avoid spawnkilling from the monsters! This place is mostly free models, basically all of it. I just edited it to make it different from all the other normal places. Trust me, it's different.
