About This 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

One of the most realistic zombie survival out there.

This is like one of those good old zombie movies. Zeds ain't joking, you have trouble if you go anywhere than teh head. You'll see some runners here and there but with a good teamwork they can be dispatched real easily without taking a scratch. There are also child zombies, taking them down is a bit sad really. Overall a real hardcore experience, you'll stress out a lot. Lemme explain.

Almost all teammates are down, some were eaten by zombies, some were put down by you when their dead bodies attacked you... Not even a single bullet in the mag, only your axe and you. Shatload of zombies slowly making their way to you... And then you see the escape vehicle! Your teammate and you rush towards it but he gets grabbed at the last second.. Nothing you can do but escape while listening to the sound of flesh getting ripped off behind you... Dat feeling when you finish a campaign...

Talking about teammates... You'll have some trouble finding decent ones because oh boy.. This game has one of the worst communities I've seen. You usually run into 9 yo kids who spam mic and take all the ammo they can carry (which'll leave the rest of the team a lot less especially on objective maps where ammo is scarce) and then proceed to spend a whole mag on 1 zombie. Of course when they die, you'll find all kinds of ammunition dropped from their bodies. That is if you can GET to the body before one of the vulture players pick all the ammo clean. NO. This is not how it works. This is not L4D.

If I buy a game that I KNOW it requires teamwork, I read the guides to have an idea what I'm about to do before joining a game. Just to not make the older players sick. I might perform bad, not everyone will succeed on their first try. ESPECIALLY in this game... But not these people. Hell I'll be happy if newbies just listened to older players instead of running around wasting bullets. Sadly no. You got hoarders, spray n prayers, little kids and people who don't understand English. This is %90 on public servers. BUT if you play with your friends or find at least 3-4 people that uses mic/chat by any chance, then you can go on for hours.

I'd pay the ♥♥♥♥ out of this game just to have a decent player-base. Because it definitely has lots of content, even more than some $$ games I'd say...

The word "realism" in the context of a fantastical setting such as that of a zombie apocalypse may seem a little bit out-of-place, but No More Room in Hell is to Left 4 Dead as Insurgency is to Call of Duty. The overall concept may be similar to other zombie apocalypse co-op adventure games, but the mechanics favor a level of real-life authenticity that others lack, and it's much stronger for it.

One of the biggest differences is how rare guns and ammunition are. Finding an M-16 with a whole entire full magazine is a treasure to be coveted and a tool not to be wasted. Much more common are six-shooters, 9mm handguns, lead pipes, fire axes, and more of their ilk.

Ammunition comes in different calibers that must be matched to the appropriate weapon. 5.56×45mm NATO cartridges used in the M-16 won't fit into a .357 revolver, and .22s useful for a Ruger rifle will be rather useless when you only have a double-barrel hunting shotgun instead. It's paramount that the players share ammunition with each other to keep everyone armed, especially when someone finds ammo they can't use but know someone else can.

Melee weapons, which come in a wide variety in levels of effectiveness and inventory weight (more on this later), will be the real primary weapon for dealing with most zombies, especially when there are many players in a game (resulting in a much thinner distribution of ammo; unlike Left 4 Dead, more than four players can play together, depending on server settings). While melee weapons do indeed follow the zombie apocalypse adage "swords don't need reloading", using them comes with a significant risk: not only can players not see their own health levels and take no insignificant amount of damage with hit, and not only will zombies sometimes grapple onto victims and stop them from moving, but players run the risk of being bitten and infected.

Infection cannot be cured; only temporarily staved off with pills. Infected players can ultimately complete levels together with non-infected players, but without a steady supply of pills, they will eventually drop dead and their corpse reanimate as a fast zombie. As infection worsens, the player's vision will gradually become more obscured, until they are eventually completely blind. If friendly fire is enabled in the game, this would generally be a good time for another player to put the victim out of their misery before they have to deal with another zombie.

Players can also start bleeding out after being hit. Their health levels will slowly deteriorate over time until a bandage is applied, adding another important tool to keep an eye out for. When a player’s health becomes critically low, their vision will turn to black and white. This is the player’s urgent warning: find a medkit, find a bandage, find something or you’re toast.

There are a multitude of tools and items to be found in No More Room in Hell. Pills, medkits, grenades, guns, melee weapons, and gas cans all make an appearance in identical or similar roles to their Left 4 Dead 2 counterparts, but added are flashlights, radios (players can only hear each others' microphones if they are near each other unless they are carrying radios), welding torches, bandages, individual ammunition boxes/half-spent magazines, and more. Every map is peppered with item spawns, but the sheer variety of them can make it difficult to find the specific one that's actually needed.

It's entirely reasonable to leave an item pickup where it is because it might not be worth carrying in your inventory at the moment. Inventories are separated into two sections: guns/items, and ammunition. Both work on the same system - the item's size and weight affects how much space it takes up in your inventory. The closer your inventory is to being full, the slower the player will run. Carrying around both a sniper rifle and a pump-action shotgun may be a powerful combination, but it will also leave very little room for other equipment. It might be wiser to give one of the weapons and its accompanying ammo to a teammate, or even to simply leave one of them behind.

The zombies themselves come in the slow, shambling variety, many of whom will ignore the player if they don’t linger around for too long. They can soak up many bullets to the chest, but will crumple quickly with one or two shots to the temple. Occasionally, a fast runner - or even worse, a half-height running child - will appear and chase down the players; these enemies especially dangerous not just because they can attack the player faster, but also because they are harder to hit while being just as durable as a normal zombie. This forces the players to make a split-second decision: risk infection by trying to hit it with a melee weapon, or burn through large amounts of precious ammunition to gun it down before it gets close.

Levels come in two modes: objective and survival. Objective mode is analogous to Left 4 Dead's main adventure mode. Players must work together to travel from point A to point B, scavenging for supplies and overcoming obstacles along the way. Routes and obstacles, in a similar manner to Left 4 Dead’s system, vary randomly. However, unlike in Left 4 Dead, the different routes can sometimes be dramatically different from the others, and some levels even can be played backwards. This adds a great amount of replayability to the official levels, and there are many quality player-made maps floating about, as well.

Survival mode tasks the players with not only simply surviving successive waves of zombies, but also with defending certain zones on the map from zombies. Players will receive a supply drop at a random spot between waves containing random weapons and items, which must be found and used in enough time to return to the holdout area before the next horde of shambling monsters arrives. Both surviving every wave and protecting at least one of the zones will achieve victory, but failing in either will result in a defeat. The quality in survival maps varies; some are significantly more fun to play than others, but there are, of course, many custom maps for this mode as well. Simply put, it’s an interesting alternative to the Objective mode that some players might hate and some might prefer.

The game definitely has that distinct “Half-Life 2 mod” feel to it (which is to be expected given that that’s what it started as), so don’t expect any revolutionary graphics or animations. The gameplay is the important aspect here, though; No More Room in Hell is an excellent example of the “graphics alone don’t make a good game” argument. That said, the age of the Half-Life 2 engine does come with some limitations, namely in the netcode: a high ping to the server can make zombies significantly more difficult to hit, especially given how important headshots are.

tl;dr: No More Room in Hell is a unique take on the co-op zombie survival adventure game that puts a slower, more realistic spin on Left 4 Dead’s formula. It demands that players work together and share resources if they hope to survive, but that makes the grand achievement of simply completing the level all the more rewarding. Being a standalone version of what used to be a mod, the game is free (not free-to-play-with-strings-attached; just free), so you have nothing to lose by trying it out.

Great FPS zombie survival game. Its fun solo or with other players. Great graphics, realistic animations, interesting characters and much more. No story playthrough, although it has objectives and survival maps. Its more like a freeroam zombie apocalypse game as well. Free to play, would love to play with any friends if they download the game.

I wish more people would play this, No More Room in Hell deserves greater attention.The game is more creepy than scary and emphasizes on teamwork. At first i found it disturbing that you get to kill zombie kids, but it adds to the realism. It's not like kids, dogs, and cats would magically disappear in the event of a zombie apocalypse. I like the fact their is 8 player co-op, but sadly hard to find people to fill up the servers. Decent amount of guns, love the ironsight feature wich lets you put that precise headshot to save bullets. what is wrong this game? nothing really. Why don't people play it? well, gamers ask for realism and as soon as you gave it to them they move away complaining " it's too hard, it's not fair, it's not balanced, he's OP..." and so on., next thing you know you have a great game collecting dust. If you want the realism without the kids try Contagion. The game is free, and it has tons of content; i say give it a try and if you like killing kids...well you should get yourself checked.

This game is not a masterpiece... No way is it a 10/10 for me... But for a Free to Play title, it deserves a good 8.5/10
One thing that really is heartwarming is the lack of microtransactions, this game is purely based on luck and co-operation... You cannot do it alone, there's no way you will survive alone...
The features I love to see are:
Players don't turn into Walkers, they are entirely AI...
Infection, there is a chance you will get infected if a walker bites you, not a 100% chance, but it's still there, and once you do get infected, there is no going back, you have about 2 or 3 minutes left to live, your screen gets grey, veins start running towards the center from the sides... It's a bit freaky the first time around.
Only way you can (temporarily) stop the infection are Phalanx Pills... The secure you for another 3 minutes I believe, but after your time is up, the course starts again...
Another feature I love to see, challenging maps, they can be really hard to complete, and if your team of say, 10 people actually makes it, only about 1 or 2 people make it to the end, the rest usually die due to getting left behind, getting cornered, or running ahead...
Getting lost and seperated from your team in this game is suicide... One time I was cornered, went into a back alley with only 1 entrance, I had a gun with about 25 round, shot them all out, but the more I shot the more came into the door, I tried to run out when I saw an opening, I asked for help from my team but they didn't hear me... I got pinned and died
That is how unforgiving No More Room In Hell is...
It's a very good game... but not perfect
8.5/10 it is
Must try this title

If you go in this with the same mindset as Left 4 Dead or Killing Floor, you're going to die faster than you can say "♥♥♥♥ ZOMBIE CHILDREN AND ALL THEIR TERRIBLE HITBOX SHENANIGANS!" as zombies keep spawning out the maps ♥♥♥, and they're hungry for players, and blocking doors, and inflicting you with the sniffles.

Ammo is scarce, everyone has terrible fatigue and is in serious need of some Gatorade™, or at least some Restore Fatigue potions, you have less inventory space than Chris Redfield on a bad day, and that .exe ♥♥♥♥ likes crashing every bloody map change (best enemy).

So you and you're overly fatigued friends need to quest for annoying prop_physics and func_physbox (s) keys and other items to akwardly lug across the map, and scrape across a door, or whatever the trigger_once is hovering over....

Well enough Hammer lessons, because theres a zombie brat 5 feet away from you ready to randomly kill you in 1.5 hits because of the random nature of the game and shoddy hitboxes.

7.5/10, would not make a Resident Evil 2 mod out of it. That's what Source SDK Base Singleplayer 2013 is for.

Holy fricking moly I don't even know where to start. Let me see. The ideas used here is really really well thought out and has rather cool functionality.

I can check my ammo by actually taking the clip out, barricade doorways and windows with planks and a board, kill big horde of slow moving but deadly zeds, the infection system, melee weapons and so much more.

I wonder what else this game has to offer?
