Full Changelog 

New Official Maps

We've had a number of requests for new objective maps so for this update we've included 3 brand new objective maps: nmo_Brooklyn, nmo_Cleopas & nmo_Zephyr. Also for those survival mode fans out there we've included the survival map nms_Midwest.

New Characters

We're happy to show the three new additions to the NMRiH character family: Butcher, Badass & Roje! It's been a long time in the making and we still have a few potential characters in the works but those of you who've been following us a while know we run on valvetime.

New Weapon - FN FAL

Even with the large number of other content features we've managed to include a brand new weapon to the game the FN FAL.

New Difficulty Modes

Difficulty modes has been on our todo list for a while. Finally we've got a new "Casual" mode for players who want an easier play experience with Unlimited respawning and faster/improved respawn token system. We only made one small change to the "Classic Mode" survival game type, which is that respawn tokens persist between waves.

New Voice Sets

A very special thanks goes out to Pugman & Chippants of PugmanPlays. They created a two player lets play a little while ago (which you can watch here) and we liked it so much we decided to get in contact with them. Long story short they recorded our two newest voicesets!


Beta 1.08 Trailer

August 13th, 2014 by Xendrid

Free beta 1.08 Steam update is coming soon! It will include the FN FAL, gunshot suicides, two new official Objective maps + two community maps, difficulty levels and new player spawning! Changelog will be posted sometime next week.

Small Update

April 25th, 2014 by Brentonator We've pushed out a small update for the game. This update includes source engine updates from Valve, such as the recent server security issue most notably affecting Gary's mod.  

  • Updated to latest SDK2013 binaries 
  • Added cl_connectmethod to PlayerInfo. 
  • Added engine interface for Account IDs. (sync'd steamclient) 
  • Various checks to make sure file transfers are genuine. 
  • Restricted MOTDs to begin with http(s). 
  • Common engine crash fixes

If you own a Windows Server you'll have to update the SDK2013 Base files manually via SteamCMD: 

app_update 244310 validate

You can check if your game has been updated by running the following command (output is shown as well): sv_setsteamaccount  If you get "unknown command" your engine has not been updated.

Some servers have been having issues with users connecting to Chinatown. Users have also reported an error "Netchannel: unknown net message (42)" while trying to connect. If either of these issues are affecting you, you will need to request the server owner verify their installation. If you update with the -verify_all command it should resolve the issue.

1.07.9 Update Released

March 7th, 2014 by Brentonator

1.07.9 is finally out. It introduces a new weapon, a new survival map, a new objective map, a few dozen fixes, and an easier way to get into the game.

Camp Blood - A lakeside camping trip gone wrong, you're the only survivors left and there are rumors of a horde of zombies coming your way. Fight your way to an interesting (and sometimes hillarious) ending.
   [pictured in header]

Junction - An amazing new objective map with an exciting ending made possible by ThoughT's excellent music composition and Hypnosis' level design.

Server Tags - You can now quickly find servers where you can spawn after connecting. Click "Add common tags..." on the bottom right of the server browser and select "Spawning:Active" to list only servers where there are at least 25 seconds left to spawn.


Future Plans

We haven't talked much about the future plans of NMRiH, so let's do that real quick, shall we? Our top priority right now is useability. We realize that people are frustrated with too much downtime during death and waiting for new rounds to begin. In 1.07.9 we introduced the very first step (a small one albeit) in making the game easier to play, thus more fun. The common tags mentioned above. This is just a small thing and we have bigger changes and improvements planned. We have listened to the feedback over this, but if you'd like to further discuss it head over to our Forum!

As for second priorities, new content is always being created. We have a couple new features that are close to done, but we don't want to make any promises or tease anything until we have them actually in the game and ready.

As always, thanks for playing!

MOTY 2013 + New Maps and Weapons

December 12th, 2013 by Xendrid

You did it! No More Room in Hell was nominated for the Mod of the Year Awards 2013! So what now? Now  comes the final voting for the awards. We must call upon our awesome  community once more.


Development News

As  of right now we are working on wrapping up some major features that we  have had in the works for awhile. If you thought child zombies was a  controversial topic, wait until you see what we have planned next!  Expect a video sometime early next year.

Our level design team  has been busy updating current maps and Hammering out new ones. Here are  some WIP screenshots of two new upcoming maps:

Now Available On Steam [FREE]

October 31st, 2013 by Xendrid "Two years. That’s how long it has been since our team’s first release of No More Room in Hell, to the day. It was October 31, 2011 and we were nervous, frightened, anxious, terrified and more excited than we ever thought possible. At least, that was until today. It has been a very long and strange path from this game’s humble beginnings as a pre-emptive mod for Half-Life 2 started in 2003 by a doe-eyed optimistic young go-getter named Coleman Sweeney, to my inheritance of the No More Room in Hell name, all the way through until today: our breakthrough release on Valve’s Steam platform.

Today we are bringing to the world the best version of No More Room in Hell to date with more content than ever before. Although we believed that the anticipation and excitement we experienced during the original release phase of No More Room in Hell could never be surpassed, this new cornerstone in the games development has proven that thought very wrong. To be delivering a game made solely from passion, fandom and friendship on a premiere platform like Steam to thousands of players is both mind-blowing, and humbling.

Our game is, as always, 100% completely free. All we want is to deliver a fun experience that we hope all of our fans new and old enjoy together.

Ladies and gentlemen, my name is Matt ‘Maxx’ Kazan and as project manager it is my pleasure to present No More Room in Hell 1.07, now available on Steam."
