So 1.08 is set is planned to come out later tonight if testing goes well. For those of you who can't wait a few hours we have a beta branch live up on steam which you can find out how to access here.

While you wait we've compiled a list of a few features you can expect to see with this update.

  • 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 a 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!

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

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

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

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
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.

It's a free game, so I expected it to be a quick 30 minutes of fun... But after initially playing it non-stop of a few hours, I soon realised that this is a real gem of a game. It stays true to the classic zombie genre with the slow walking zombies but it has it's fair share of "runners" too. The atmosphere is very dark and gritty, it's perfect for zombies and I love it. There's dozens of weapons ranging from guns to melee. There's always room for trying new strategies for the hordes of undead. There's a modest number of maps but each map has a changing structure that makes it different each playthrough. And both objective and survival gamemodes are equally fun. But as a personal opinion, objective maps are too easy as sometimes you can pretty much speedrun your way through the map and leave everyone behind with the zombies. Overall, it's a perfect zombie game and hearing the accompanying "pop" when you blow a zombies head off is pretty damn awesome. Compared to the L4D series, I'd say NMRIH is more realistic so it gets my preference in this genre. Give it a try, it's worth many hours of zombie killing.

At first this game will frustrate you, it seems virtually impossible to kill more than 10 zombies without dying yourself, and you find yourself walking around with empty guns. But after a while you learn the range of different weapons and you might actually complete an objective map! Tip: start with Toxtet, that is the easiest level to complete.

You can also play survival maps, which is the standard "kill all zombies in a wave" affair. I think the easiest level to start survival is "Night of the living dead".

Objective maps are best played with a few friends because cooperation is key in this game. Another golden tip is to kill as few zombies as possible, run run run and shove shove shove! It is possible to reach the extraction point without even kill one zombie in this game mode (and an achievement: pacifist).

Overall a nice game with a steep learning curve.

There is, I must admit, a niche for games that are harder than hard. A game which is not gentle, that does not have a learning cure so much as a learning cliff. A game which shows nothing but brutality to it's players. This game is a labour of love, with many, many hours obviously put into it to make as best a game as the developers could. They knew what they were going for, a semi-realistic zombie apocalypse that shows no mercy and they went for it.

Of course, this introduces problems.

Let's start with the learning curve. As mentioned before, this game has not so much a learning curve as a learning cliff, so you might expect a short moment on how to explain game mechanics, or at least, hints and tips while the game loads for you? Reasonable to expect, isn't it? Well, no. You don't get that at all. There is no kindness, no compassion, no one or nothing to give you a holding hand; this game chucks you in the deep end, then expects you to know breast stroke. Now other games have done this, Dark Souls being the most infamous, but Dark Souls took a moment to explain what was going on. It told you how to raise your shield, explained how to equip, and how to use the bonfies. No such luck here. You're in a bulding that is secure, and the moment you walk out that door, zombies. Lots and lots of zombies.

Now having one or two zombies at first to get used to them, to know how to deal with them, again, would be standard fare. Nothing wrong with being exposed to a new enemy type slowly, to let you understand and get used to. Not so with this game, oh no. Try a few dozen. And you don't know what to do beyond kill. You might have a few weapons, but they float through the air, seemingly not connecting to anything, which means that you have to spend a few swings getting used to weapons. And in a game this lethal and unforgiving, those few practice swings will cost you dearly. And you will die.

Now one mechaninc that you might know is that being grabbed can only be resolved by pushing (which is V by default). What you may not know is that zombies can grab through wire fences and windows (wether or not this is a bug is something else entirely) and if that happens, you are beyond all hope. Another thing that you might guess that being grabbed and then bitten is bad, and it is, but being bitten is not well shown. Beyond the zombie jerking a bit, you may not even know you've been bitten until you begin to show the signs. And if you are bitten, death is inevitable. You have two minutes. Spend them well by either finding pills to buy you more time (no cure here), jump off a ledge, or simply beg someone to kill you.

Now the inventory may take some getting used to. You have two inventory wheels, one for ammo, one for weapons. The bigger, bulkier, and heavier something is, the more space it takes, and you don't have many pockets. So of course you need to manage inventory space, which is perfectly fine, this is a horror survival game after all. Nothing wrong with that. In fact, I applaud it. I don't want to be carrying two rifles, three pistols, and a big ♥♥♥ sledge hammer. I'm not a ♥♥♥♥♥♥♥ space marine here, and this isn't the game for them. Ammo is counted in weight and mass as well, which makes sense.

And, of course, the zombies. Oh, the Zombies. These are standard Romero-Zombies. Undead who feel no pain, fear, or emotion and operate entirely on instinct. Woth noting, hwoever, that the eyesight of a zombie is perfect. I'm not kidding; they have perfect, near 360 degree awareness of everything that not even you or I should be able to see. Two stories directly overhead? They can see you. Small dot on the horizon in a darkened room? They know you're there. Pitch blackness? Sure as ♥♥♥♥ they know you're there.

And while this does make for a fun and entertaining horror game, there is one more flaw. Multiplayer. Now, I know what you're saying: But Left 4 Dead and Payday did it perfectly! How can this be possible!? Well here's why. For starters, Valve knew that players can't communicate well with strangers on the other side of the world. They knew that coordination was next to impossible. They knew that players naturally deviate from each other at all times. So how did they solve this? Simple. You always knew, at a glance, how your fellow players were doing, and where they were. They had glowing outlines that showed at any distance, and maps were linear to prevent fanning out by players. Maps in valves games were funnels, and even Overkill understood this by making the map around easy to navigate and open buldings made as simplistic as possible.

Multiplayer is a mess. Players do not communicate well with others over large distances. Most players don't even have microphones, so that idea with walkie talkies where players far away can't talk without them? A waste of time since text speech does not work with walkie talkies, so you must be right next to them to work. Maps are cramped, narrow things that while linear, often curve in on themselves and encourage exporation. Again, not a problem, except that players naturally do not drift together, they drift apart because they have no sense of surroundings at the best of times and are given no way to drift back together.

This game strikes me as a single player game trying to do the work of multiplayer. It just can't work. It doesn't work. Bad bugs (or bad mechanics, that's unclear), an extreme difficulty curve beyond any sane resembelance and poor combat mechanics and jerky, overwhelming numbers of undead at all times mean that players will only have an experience of death, more death, and of course death, all without any real progression. This game isn't just hard, it's near unplayable through it's obscene diffculty spikes and poorly designed multiplayer maps.

This is not to say that it's bad, heck, I had loads of fun playing it, but it is very much a niche game. If you don't want to play this sort of game, skip it over, but I reccomend playing this game just for the experience.
