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.

I'm going to try and make this a longer review, since most of the others people make for this game are 1-6 sentences average.

No More Room In Hell (NMRIH) might seem like something to pass on at first glance: after all, aren't there tons of HL2 modifications all over Steam? (and yes, this is modded off of HL2) True, there are a lot, but this does not mean NMRIH is the same as any other bad remake. In all honesty, I really do consider this game to be a hidden gem buried among bigger-name apocalyptic survival games. In my experience with apocalypse games, this easily represents the true form of a zombie takeover, how it seriously needs to be represented. A couple points on that:

- Slow zombies: Lots of other games like this make out zombies to be super resilient and fast. NO. They are slow, stupid, and ridiculously overpowered when in hordes.
- Running zombies: Yes, there are runners in this game (and quite pesky, they are).
- Realistic objectives: The objectives you must complete are perfectly plausible. In this game, you don't defend Earth from the zombie threat, you defend places like CONVIENENCE STORES from zombies, all for the sake of survival.
- Dispersal of firearms/ammunition: Again, it's pretty realistic. You are not given a huge armory to work with, you will be lucky to get your hands on a shotgun with 6 rounds.
- Child zombies: Yes, believe it or not, when zombies take over the world, there will be children zombies too! Still the only game I have seen yet to have undead children.
- Stamina system: You really can't just be swinging a sledgehammer, killing everything in your path. A couple swipes with a heavier weapon will severely tire you out, while lighter weapons take longer to do so.

But enough about what makes it realistic. Some of the most important things to note in a game:

GAMEPLAY: The gameplay is unique in the fact that it is notoriously difficult to survive. I have over 40 hours (no mean feat, when the game is so fun), and I still get murdered pretty much 80% of all the rounds. You do need some skill, and there is a system for using it: Always aim for the head with melee weapons or firearms: Time your attacks so you don't get destroyed by moving too slowly: Always shove a zombie away from you after attacking it.

The controls can be difficult to learn at first (pretty sure it took me about 1.5 hours to figure it all out), but once you have the hang of them, you are good to go. YOU WILL DIE A LOT DURING YOUR FIRST FEW ROUNDS. It helps though, as each death allows you to look for what you did wrong.

Certain maps are objective-based (do these things to be rescued), and others are survival-based (hold out against waves for a specified time). The maps can seem unusual and difficult to complete at first, but, as always, practice makes perfect. A couple full run-throughs of any map can help you pretty much memorize what has to be done and how to do it. The you will realize that the maps have a switching system that randomizes the orders of events, and you will learn it all again.

Your average zombies are absolutely everywhere. They are ridiculously slow, but nevertheless you will end up getting grabbed by one and murdered. Runners are fast and furious and extremely weak. And kids...don't even get me started on the kids. Well-timed and aimed attacks will take them all out easily,especially with the backup of your teammates.

Health is lost in large amounts when you are injured, and medical supplies are rare. In addition, there is also the risk of bleeding (slowly losing health), and being infected (yer done fer, even Phalanx won't stop it forever). Again, this system adds challenge to the game, making health management very crucial.

For the people who find survival against the hordes overated, go casual! Lots of servers host instant-respawn, infinite ammo, and gun selection menus. For all your zombie-killing needs!

MULTIPLAYER: Yes, the game is multiplayer, which makes it all the more fun. What's the point of surviving the apocalypse alone when you can do it with up to 7 more people? And as your teammates are picked off and succumb to infection one by one, you can laugh as you kill the zombies they become, knowing that you are so much more experienced then they are.

But really, having friends makes the game a great deal easier. It is important to have people watching your back and willing to fight in your place when you run out of ammo. The game is also microphone-compatible, which allows people with mics to communicate easily with the others. For people without mics, there is still a voice command system, allowing you to communicate the important things in the game, such as: Need ammo, injured, help me, follow me, etc.

You will probably quickly learn how it feels to be the only guy on the team who was not able to get a gun: It feels empowering. I love using melee, knowing that I am so much braver then my friends, since I charge in to fight while they hang back and shoot.

Overall, multiplayer is the feature that really helps make the game what it is. Without it, the game just would not have succeeded.

GRAPHICS/PERFORMANCE: I don't exactly know very much about computer processors and such, so I'll just go with what I know: The game is not demanding on systems and runs pretty darn smoothly on any PC I know of, and probably most laptops as well. I mean, it runs fine on my $300 bottom-of-the-line 2-year-old laptop.

As for the graphics, I find them to be pretty good. Not the best, but not bad, either, just somewhere in between. You should not be expecting super high-quality graphics from a free-to-play game like this anyways.

COMMUNITY: As much as I hate to say it, the NMRIH community is a bit lacking. Doesn't seem like much ever goes on here. However, it i understandable, as the game does not have too much popularity. (SO YOU SHOULD GET IT TO INCREASE ITS POPULARITY) Howver, I find that there are always players in-game, no matter what time of the day. There are way more servers than needed to handle the traffic, but you can always find some that are either half-to-mostly full.

(Reinforcing above point, I sometimes find people that have 900-1,000+ hours in this game. Seriously guys, you're kind of over-doing it.)

REPLAYABILITY: Technically, the game does not qualify for "replayability", as the maps are always changing and such. I'm talking about how long one can play it before becoming increasingly bored. The answer: Probably about 10 hours. At least, that's what I see most people do. They average about 10 hours, complete some maps, earn some achievements, and just abandon the game entirely. THIS IS NOT WHAT YOU SHOULD DO, REVIEW-READER. I would recommend playing 45 min. - 1 hour a day, it helps sustain your interest over a long period of time.

Going back to the thing about the maps changing. There are lots of maps available to try out (I still wish there were more, I can never get enough). If you don't like the survival maps (like me), just switch to the objective maps. THE MAPS CHANGE THINGS AROUND. You might think you have completed a certain map completely: Nope, there are still randomized sections you have yet to see. I think this fact really helps sustain one's gameplay. If you don't find that very interesting, then I don't know... try out different characters? ...use different voices? (Yes, you can change your character's voice set)

OVERVIEW: All in all, I think NMRIH really fills the shoes of a well-made, realistic zombie game where teamwork is the key to success. Work together or you die alone. I love the game overall, and I'm sure if you tried it, review-reader, you would too! But seriously, if you are still not convinced... the game is FREE, for goodness' sake! Download it, try it, and if you hate it (which you won't) just uninstall it!

I hope this review helped you decide. Good luck surviving the apocalypse!

I just realized how long this review is...

This game-actually, lets not call it a game, lets call it an IDEA for a game- is cancer. At first it was great but all of a sudden, it just stopped working. It felt like I played a demo of a game for only 1 hour and then it was like "WELP YOUR PLAYTIME IS OVER". Haven't been able to play it since.

Things I like about it
- The IDEA of this seems great, but its really only an idea to me because it obviously NEEDS work.
- The artwork
- The fact that I didn't have to pay money for this garbage

Things I don't like
- I can't play the damn thing
- ♥♥♥♥s with my computer making it unusable for a good amount of time until I can close the game (which takes a lot of effort apparently)
- I have to restart my whole system in order to exit the game, I can't just CTRL+ALT+DEL or anything like that.
- It exists

This game honestly surprised me. I, myself am not a free to play type of person, in fact I think most, 90% of free-to-plays are absolute ♥♥♥♥ designed to try and suck money out of me. Not this one, this is up there in some of my favorite f2p games, and yes, I'll admit, this game isn't without it's flaws but it's one game that has semi changed my opinion on Free-to-Play.

Let me start with the good, for a Source Game, an engine of 10+ years, this game looks great, apart from zombies looking like they came out of a low budget B-movie horror flick and the no texture bug which appears on the eyes of some characters (I laugh this one away and think of it as an intended bug for immersion) it's pretty good. In some of the settings, they've hidden away a few graphics options that are experimental such as Lens Flare but is worth enabling. NMRiH really immerses you into the thought that you are a survivor and must get through this with it's graphics, the vanilla maps have been designed very well for immersion in mind. The lighting creates this bleak atmosphere that not many other Survival Horror games create, Left 4 Dead (yes the lighting is still very good but not like NMRiH in any way), DayZ to name a few. It keeps to a certain design framework that really wants to keep you immersed and constantly on alert as every dark corner there may be undead lurking. It emphases the use of Flashlights which are possibly one of the best utilities seen in any game I've played.

Away from the Atmosphere and the Graphics, the combat matches this very well. Ammo for guns is rare, something that really does fit a realistic scenario of such a thing happening and it requires you to make every shot count. Melee combat is interesting too as it has an invisible stamina meter, requiring you to time your swings and make every bit of your energy count. Weapons like Sledgehammers, FUBARs and Shovels drain it more but with the chance of one hit kills and possibly killing multiple zombies, other weapons, like Machetes, Hatchets, don't do as much damage but use little stamina, keeping you on in the fight. That moves me onto the next great thing about this game, the variety of weapons and how they each have a destined purpose. Pistols are great, they're all different and have their own specialties. The Beretta M9 is a 9mm Pistol and the ammo is rather common, it's a 2 hit kill and my favorite pistol due to the sights being better than that of the other 9mm, the Glock 17 which has a larger ammo capacity but worse sights, again in my opinion. Weapons are so varied with it's uses that they're all worth trying to match your game style. Would you like to pick up the M16 or would you rather take a more recyclable approach with a Compound Bow.

Other mechanics in this game away from combat is the ability to become infected and must be warded off with Phlanx Pills (a reference to one of my all time favorite novels by Max Brookes - World War Z) or Gene Therapy, which completely cures you. You can barricade entrances with a claw hammer and some wooden planks, end your teammates (or yourself) to rid them of the burden that may encumber you later in game and more. You can even change your character and his voice. I'm not going to go much more in detail with the other mechanics, these are the best ones, so you'll have to encounter some of the other ones in game yourself.

This section is dedicated to the AI and the Level Design. I'm not gonna lie, the AI really needs patching up, it's ♥♥♥♥ing ♥♥♥♥♥♥♥♥ and needs some work. However it's predictable and unpredictable nature (yes the AI is both) keep you on constant alert. An infected teammate has gone down, where the hell could he be? Well he's glitched out running in circles around where you turned. That's one major issue with the game. Away from AI, the levels are really good. If you're playing slowly, they can sometimes take up to 30 minutes to complete and can be quite the blast if you're last man standing. The maps, each and every one of them are unique and require different objectives and many of them have different paths for different playthroughs. Not major though, but something to change up gameplay each time.

All in all NMRiH is a great F2P game, a slightly cancerous community as I've encountered many annoying little kids in my mere 30 hours of gameplay but overall pretty damn good. 8/10.

+ Runs with different Windows, Mac systems.
+ Looking nice.
+ Soild allaround game. Especially F2P, so u can check this game out. Its wort it.
