Released in its original beta form all the way back in October 2011, No More Room in Hell has had quite a storied history. A co-op first-person zombie shooter, No More Room in Hell was developed by Matt "Maxx" Kazan as a mod for Half-Life 2. The game was eventually given a standalone release on Steam in 2013, where it continued to grow a sizable cult following. Three years later, No More Room in Hell 2 was first announced.
