No More Room in Hell (abbreviated at NMRIH) is a 2011 cooperative zombie survival game on the Source Engine.
Objective maps involve completing a random set of objectives that follow a general linear pathway through a map. Items are scarcely distributed along the pathways, and occasionally respawn points can be found.
Ultimately, the gameplay in this game is compariable to games such as Left 4 Dead. The pacing is a lot slower, rather than move around a series of maps, a campaign is usually contained within a single map with a randomized series of goals. Zombies are slow, but are almost constantly spawning and can overwhelm an area quickly. Resources, like ammunition, is scarce; players are often reliant on melee weapons which must be used carefully at the cost of stamina.
Players can bleed and or get infected. Bleeding is a gradual health drain until they use a bandage. Infection will appear to a player as veins appearing on their screen, followed by steadily darkening vision until their screen is pitch black, then they will pass. Their corpse will return as a running zombie. A player can delay the effects of the infection using pills, and completely clear it / immunize themselves against it using the Gene Therapy item. Players also have the option of taking their own life with a firearm to prevent themselves from becoming a zombie.
