Patch 1.09 is now out!

Before we start

Before we go any further, Server Owners please join this group for server specific announcements and help, click on this sentence to go there.

The new app ID for NMRiH dedicated server is: 317670
Starting with the next update (1.09.0) you will need to use 317670 instead of 224260 to get the latest and greatest server files.

If your game crashes click on this link and follow the directions.

Oh and let's not forget about our super duper remastered soundtrack! It will be on sale on Bandcamp and Steam Music within this week. The game itself will always remain free with no charge.



Originally I wanted to write a nice news post for this update but our Website decided it was time to spit out Error Code 503, so here's the update with no muss and fuss; happy halloween!

Below is the finalized Changelog and a description of some important

Important things that got added/fixed

Radio menus for third-party plugins
Radio/vote menus for things like SourceMod should function correctly, it only took us 3 years to fix!

Native Vote Menu
By default a TF2 style vote menu is enabled, users can choose to restart the round(the best thing about this update), change map, set the next map, and kick griefers.

CVARs are similar to the TF2 ones, so you can turn off voting/kicking if you want.

Updated SDK2013 code
We merged in the latest code from Valve that should fix any engine related bugs, the game as we know it checked out to be stable but if there are any side effects on the server end let us know

National Guard zombies
After years of having inconsistent Character Artists we managed to crank out our first new zombie type, these guys have body armor and helmets which are more resistant to most ammo types (with the exception of the high caliber rifle rounds), and have the chance of dropping some ammo or weapons.

Medical Items are fully animated
You can now equip our medical items! By mousing over them, you'll have them in your hands and if you tap your Primary Fire key (left click), you'll be able to use them; gotta be careful when you want to heal up

  • Changed version number to 1.09

  • Fixed VR mode, and is now a video option.

  • Added nms_arpley.

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

"No More Room in Hell feels uniquely more like a horror game than an FPS."
PC Gamer

"...it has enough brains under the hood to make the most sated zombie ask for seconds."

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
No More Room in Hell is a Half-Life 2 Zombification. The mod was founded in 2003. It switched hands and a new team took over in 2009. Beta version 1.0 was released on Halloween of 2011. A full list of the No More Room in Hell Team and contributors can be found on the about page of our website: www.nmrih.com.

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...

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

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.

This game is a good slow paced tactical co op zombie game
Ammo is a luxury, and a good gun is as well.
This game shows an apocalypse like it is- not only is mommy and daddy a zombie, but little Tim and Gabby are as well, so it has this creepy element to it with the children zombies. Oh and it's actually free and there are 0 microtransactions, and the devs should keep it that way.
Overall good game

This is such a good game, with great gameplay! You won't survive without teamwork, well you'd need a decent team at least, and sometimes you'll be the last one alive or you'll be making a sacrifice for your fellow comrades.

My advice for this game:
Stay away from nine year old mic spammers
Don't be a hero
Stick together at all costs
Learn that if you get bit that you still can hold some zombies back
Don't hog all the decent weapons and ammunition...
Be careful where you fire your SMG or throw your grenade
And don't bloody kill your team-mates.

This is how you build the foundation for a great coop zombie experience. No more room in hell is a free game which started out as a mod and puts most games like L4d2 and every early access zombie game to shame. If the creator and his team were funded a quarter as much as AAA game or did a kickstarter this game could easily hold the title of top zombie game.

With that said this is all free so while it has amazing ideas it is held back by an aged source engine and lack of funds to keep it well polished. Hitboxes are inconsistent with melee shots, guns sometime wiff at point blank, and the graphics and audio is limited. However if you can look past some of its faults it is a very fun and terrifying survival game where you can die at any point and watch your poor friends have to fight and claw there way to the end if they can make it! When you die you come back as a zombie AI and try to put any humans left down. The gore is satisfying especially when you hit one of those fast little ♥♥♥♥s in the head. Or ya there's zombie kids. 2 Kinds of map types objective with a L4d type mission to escape the city only it doesn't suck. Also survival mode where waves of zombies come after you in crazy enviorments. The game is updated every so often but still sufferes from bugs here and there.

In the end this is a game you and a group of buddies will deff want to screw around in. It's free go try it!

Final score 7/10

When I first started playing this game, I was a little bit sceptical about the engine it was running on.
As you all may know, it is running on source engine, the same which is present in half-life and the counter strike franchise (and many more games). The problem is, the game at first felt a little ‘’stiff ‘’. It is definitely nothing like Dead Island, and the gameplay mechanics are not fluid. However…..
After few tries, I definitely did get used to it. If you ever played counter strike or any other game running on source, you will have no problems with this.
Now, onto the actual game. No more room in hell is a basic cooperative survival zombie game. It started off as a mod for Half-life 2.
There are a few game modes, such as the survival mode, where basically you have to hold up as long as you possibly can, fighting off the waves of undead. The objective, where your team has to accomplish a task in given time. Also the developers have promised to release more game modes in the future.
There are 30+ weapons in the game, ranging from a small axe to FN FAL or a .45 revolver. You can use a hammer and wooden planks to board up an entrance, in order to keep the zombies out. You can actually get infected by a zombie that bitt you. There is also voice chat for easier communication with other players. The graphics are surprisingly good and I have not encountered any server issues or lags during my short game play. Even though at its early stages, NMRIH (No more room in hell) is a very polished game. If you have ever played DayZ….don’t worry, this game is actually playable in its standalone form 
Overall, this is a brilliant zombie survival game. It has a really gloomy feel to it and descent soundtrack, like any zombie game should have, cool looking maps and plenty of features to keep you busy kicking undead ♥♥♥. I thoroughly recommend it to all zombie fans out there. Definitely worth checking out and playing with your friends.

For a source game it is really realistic. This game is about teamwork and coordinating objectives with your team. This game is impossible to solo. Getting cut off from your group is suicide, as walkers will swarm you and eat your brains out. Remember wen you had all this ammo and you were blasting people apart, not caring about running out of ammo? In this game, you'll be lucky if you find a pistol. It makes you rely alot on melee weapons, making it fun and challenging to fight the undead horde, instead of easily brushing them away with a machine gun. If you do get a gun, ammo is very scarce, so you never waste it. Always always always go for headshots. (Mainly because the esplosions of blood are really cool) Zombies are also able to infect you, giving you limited time until you turn into a shuffling corpse. You can take pills to supress it temporarily. You can also get a supply drop every few rounds making it helpful to get more supplies. And for the P2W shop and perks, forget it. This game is 100% free to play. If you're playing pn an official server, there isn't a single cent to be spent. This game is awesome, and I recommend it to all people who like zombie games
