We started it all and are happily continuing the fight!

Game is really wonky, no clear guide on how to do things, you have to learn through they key menu, Players move too slow vs zombies and controls feel slugish all around, no real instructions on how you baricade windows, and just overall fell really flat for me. I was left sitting in a corner contemplating the game as a zombie, and decided to unistall it. Left 4 Dead or the Killking Floor series is worlds better than this, also no controler support, local play, bots or etc. People's standards must be really low if they dig this.

It blinks my PC Screen and doesn't accept 1920x1080. What... and obviously, the humans camp using protection... 3 bites and death? You can easily kill a zombie with your weapons.

I play it since its first release in 2007. Damn these were good times and actually the mod was alive back. Now you will find much less servers, but the few servers are good populated. My problem is, that some servers just run cabin or church 24/7. I would love more default maps. Other than that, this mod is great and still worth the download.

This game should be more popular than that. Let my explain why.

So, you find a good server. You join the server and a new round starts. All the people press P which grants a temporary stamina boost. You're new to the game. You don't know why they're doing that so early on. (While the players character is panicking they drop all of their weapons and ammo) You take the ammo they dropped, but you notice something.
1. All the others are way ahead of you.
2. You are now a slug with all those bullets.
You encounter an player, he has an AK-47 and seems to have quite a good amount of ammo too. But he still runs faster than you. That's because you have your melee weapon still with you and a metric ♥♥♥♥ ton of bullets. Beside that, your weapon isn't the best, as it is only a 9mm pistol.
You get killed and the Zombies win the round.
Another round begins and like last time, all the players sprint off. You decide to do the same and follow them. A Zombie follows you but he can't catch up with you. Eventually, you get lost and you run out of stamina and he catches you, killing you.
Again, new round. Everybody runs off, but this time you are with them. You find numerous places where the big guns spawn. You manage to get yourself an SMG and sufficient ammo, but not to much. You notice that you are still lighter than you were with the pistol and the full ammo stock. A few survivors were killed, leaving you and another player alone against the horde. You fight with him. He runs out of bullets. He asks you for some bullets, and you share with him. But even that isn't enough. He tells you to keep them distracted and uses his panic ability again. But you are scared of the raw numbers of Zombies, and you follow him into an basement with no alternate escape route. Eventually, you are overwhelmed. So is the last survivor that you followed.
3rd round. you run of to get yourself a gun, ammo and team up. It all repeats itself. with one exeption: You fight them off this time! And you get hit a few times, but you're still not dead. While you held the Zombies off, your teammate did the objectives and you manage to escape. Congratulations!

This little story here is similiar to how I started out playing. It teaches you to share ammo, work together and communicate. It's an competitive game, you won't win by yourself. (Well...rarely)
1. Don't carry to much ammo, instead, share!
2. Learn the spots for all those goodies waiting. In the late stages of a match your pistol isn't going to do the job. (Small clip, slow rate of fire etc.
3. Don't be scared to take a few hits. "Normal" Zombies can't infect you with one exception: The Carrier (a.k.a Whitey)
He has a chance to infect players

I just realised this is more of a tutorial than a review. But hey, still shows how much fun it can be if you work together or with friends.

I want to say that I played this game for the community and the amount of fun and excitment it could generate. Sure the maps that people generally prefered got more terrible and campy but damn I loved this game. I admined for a long time in it and like to think we all shared something special by playing this unique game together. Time has passed but I'm currently downloading this to play it again in hopes that the community hasn't turned into a a collection of unskilled and overly cautious players that only play garbage maps where it sucks to play zombie. That was, in fact, the direction it was headed when I last played it years ago. Here goes nothing.
