“This is the definitive sleeper pick for "Favorite Co-op Game with Friends" This isn't exactly a new game, nor is it a game at all. This is a modified version of the GoldSrc engine, also known as the Half-Life 1 Engine.…”

“Quite broken at times, lots of error entities straight out of GMod, but very silly and worth playing with friends for a while. Glad to see there are people active on this game.”

““Half-Life… but with friends. Which makes it 10× funnier and 3× more chaotic.” Sven Co-op is the magical experience of trying to survive a serious sci-fi disaster while your friends do the absolute dumbest things possible. One guy is solving puzzles. One guy is shooting…”
