"NMRiH is a stand-out take on survival and the scariest multiplayer game we've ever played."

About the Game

"When there's no more room in hell, the dead will walk the earth."

A tribute to the highly acclaimed film series in which the above quote originated from, No More Room in Hell (PC Gamer's Mod of the Year 2011, ModDB's Editor Choice Multiplayer Mod of the Year 2011), is a co-operative realistic first person survival horror modification for the Source Engine. Taking inspiration from George Romero's "Of the Dead" series, the mod is set during a time in which the world is on the verge of collapsing into chaos from a disease whose origin is unknown. Many experts and organizations have their theories and ideas on how such a disease emerged and started to systematically destroy our very way of life, but one fact is clear to all. Whoever perishes from the disease gets up and kills, and the people they killed get up and kill.

The chances of you surviving this all out war of society and the undead are slim to none. Already, there are millions of the walking dead shambling about, searching for food to eat. There's no known cure. One bite can possibly end it all for you. However, you aren't alone in this nightmare. There are still a handful of uninfected survivors left in this god forsaken hellhole, and with co-operation and teamwork, you may live long enough to fight your way to salvation.


  • Teamwork: Co-operative play with up to eight players.
  • Voice and Text Communications Limited by Distance: The further you're away the harder it is for other players to hear you. Keep those walkie talkies close!
  • Dynamic Objective Maps: The next playthrough may not be the same as the last!
  • Survival Mode: Defend and maintain your shelter against the undead in the hopes of getting extracted to a safe area.
  • A Realistic Approach: In short, no crosshairs with limited "only when you want it" HUD. In addition, ammo and weapons are extremely scarce. With that in mind, aim down your sights and shoot for the head!
  • Multitude of Different Opponents: Ranging from the iconic "walking zombie" to the more contemporary "runners", NMRiH will keep you on your toes with a mix of dangerous foes to face down. However, the most dangerous enemy may not always be the walking dead...
  • Infection: One bite may be what it takes to bring you down. If infected, you must decide if you want to alert your team to rid you of your burden, or to keep quiet in the hopes of finding a cure...
  • 30+ weapons and counting, ranging from the diminutive .22 Target Pistol, to the almighty Chainsaw.
  • No pay to win items
  • No ads
  • 100% Free

Planned Features:

  • National Guard NPCs - Will they help you or see you as just another walker?
  • Full dismemberment - gibs for arms and legs instead of just the head
  • More gamemodes including a mode that mixes Survival with Objectives
  • New and varied zombie types - SWAT/Military zombies with body armor
  • More playable characters (including females)
  • Stat tracking along with Steam Achievements - With the possibility of unlockable items
  • More frequent updates with Steam support
  • More maps and overall content with Steam support

When a game mod takes about seven years to be made into a stand-alone game and have an official release on Steam, you know it's worth playing. No More Room in Hell is that mod. Starting out as a stand-alone mod for the Source engine, No More Room in Hell is a zombie outbreak simulator that is unlike any other that has ever been made. The game features a unique atmosphere, AI, weapons, and maps that can keep people satisfied during their play. Even though it may not be as exciting as other zombie games, such as Dead Rising, the game centers more around fear and survival more than just fun antics. Now, the big question is, is No More Room in Hell worth my hard drive space? If you are a die hard fan of zombies, and want to have a more realistic approach at it, I'd definetly reccommend it.

The Verdict: I give No More Room in Hell a 9.5/10 for it's deep approach at survival and realism

I would highly reccommend no more room in hell to anyone who enjoys an FPS, Horror, Action or survival. With ailments such as infection and bleeding, and other such things, makes this not only one of the best, but also the most realistic, zombie themed games ever made.

No More Room in Hell, at its simplest, is a brutal, "Romero-On-Steroids" take on the zombie apocalypse sub-genre. Intent on creating as realistic (or, in the words of the developer, "Romero-style") an experience as possible, nearly everything is accounted for in this game, outside of the usual "stamina" and "limited HUD" features. Each individual item has its own weight, and is allocated to an inventory wheel, which the player can access at any time. A shotgun, for example, will weigh more than a machete (and consequently, take up more space than that machete on the wheel). Even your total ammount of ammunition is accounted for, and thusly limits your inventory space. Don't take this to be an inhibiting feature, though. If anything, this system adds to the terrifying immersion of the game. Certain items that are normally a "given", such as the flashlight, must be picked up manually to be used at all (but can be accessed quicker than other items by the usual 'F' key once it's picked up). The zombies themselves, as they always have in Romero's movies, are generally slow, and do not pose any threat if they're alone. As you progress through the waves, however, this "lone target" situation becomes decreasingly common, and replaced with crowds of zombies, often numbered in the tens to even twenties. Unlike other horror (or even generalized co-op) games that permit cooperation but do not enforce it, No More Room in Hell sternly (but not forcefully) nudges players into a peacefully-woven experience, complete with suppressing and covering fire, shared supplies, and coordinated strategy.

tl;dr - No More Room in Hell is one of the best zombie games you'll find this decade. Play it.

A game inspired by classic zombie movies. Big variety of weaponry: from M1911 to M16A4, from machete to sledgehammer, from molotov cocktail to frag grenade; Challenging gameplay: what if you get infected or run out of ammo when cornered?; Cooperative teamplay: working as a team to survive - what else you could ask for a good zombie game? Also, it is FREE, so what are you waiting for - there is nothing to lose! (except for your time, haha)

This game is very interesting and realistic for a zombie game. It was once a HL2 mod, and the graphics are very similar to it and Garry's Mod, which is another reason I like this game. Plus its free to play, so if you're a Half Life or Gmod fan, you should give it a try.
