Best for tense co-op horror: No More Room in Hell
Steam describes No More Room in Hell as a cooperative, realistic first-person survival-horror modification for the Source Engine. Its survival focus, scarce ammunition, and infection make it a fit for groups that want careful movement and supply management rather than a run-and-gun pace. The listing notes more than 30 weapons and co-op for up to eight players.
Steam lists the game as “100% Free (unless you buy the soundtrack DLC).” Its listed release date is October 31, 2011. That makes it the clearest pick here for a larger group seeking old-school, resource-conscious horror.

Best for mission-focused teams: Codename CURE

Best for open-ended survival: Unturned
