ZombieMod is a server side modification for Counter-Strike Source. The aim of the game is to conquer the attacking zombies or kill all humans depending on what side of the field you currently are. The game may be played on any map, and users join a server like any other CS:S server without any pre-requisites. The plugin was designed so that it may be run on either Windows or Linux Source Dedicated Servers with a minimal instalation time.

When enabled on default settings, the level is loaded very, very dark with fog all around. All players spawn normally and you cannot hurt anybody; Rifles and the MG are restricted.

After a random amount of time (2-10 seconds), one player is changed into a Zombie complete with model, unable to use any weapon other than the knife, and is given 5,000 health. He is changed to the (T) team and everyone else to the (CT) team to allow for an operational scoreboard. They can also run alot faster than humans, are provided with night vision and have a 125? ?Field Of Vision? instead of the regular 90?. His only goal is to infect as many humans as possible by slashing them once with the knife, each scoring him one frag. Each subsequent Zombie is given 2,500 health, moved to the (T) team and also reduced to using their knife only. Zombies are knocked backwards with each shot so their only hope of survival is attacking in numbers. A few well aimed shots to a zombie?s head and it comes off complete with blood spray!

Zombies can only use voice with other zombies, the same goes for humans.

The round ends when either all the Zombies are killed, or all Humans have been turned to zombies.

With a team of dedicated Administrators and Coders we try our hardest to get ontop of Valve updates almost instatly and hopefully in the near future no updating will be required after a Valve Steam Update. Each update is a learning process and we have almost eliminated all update quirks.

ZombieMod 3.0 CS:S OrangeBox

Yes folks you read it right, it's finally is here!

Change log and download link are below. Speed is still an issue, zombies are faster than humans but so far I have no proper way of editing the speed the same way I could before Orangebox, you can thank Valve for that 

Have fun folks, and watch the beta forums for the progress on the new features I'm beginning to think I can start to allow into the plugin 


- Fixed variables in config file, the correct variables are zombie_money and zombie_humans_jetpack.
- Fixed zombie_listclasses output, there was nothing wrong with the classes it's the speed setting that's not working correctly, I think 400 is the maximum speed.

well, to the guy up top whos talking about the mic thing. theres a little button called MUTE. Second, i love zombie mod. I play it b4 it crashed and they had to rewrite it. I thought it was more fun b4 they came out with this plugin. First, there was only 1 server, which i found by accident. 2, No1 knew about it, so the same people were coming, they wernt all litle kids, but more mature. Three, the zombie maps back then ruled. the maps today seem too weak with not enough objects to barricade with. maps like OfficeRampage6-10 and officeattack1-2. i go onto zombie mod servers now, and i dont even see those classic maps anymore. It makes me sad to see the map makers not put enough objects to block with. Like some1 else said, now every1 is playing it, but its not the same anymore.

"To reach a human in a tube, the zombies must form a line to keep the first one from being knocked back by bullets, alllowing him to progress forward and tag that human."

That never really works that well.

This mod is not only loads of fun, but highly addictive! Two thumbs up! The only problems lie with over half of the servers who change the settings in a way that ruin this mod.

The most common way is setting the weight of world objects WAY too low! This makes all the objects, despite their size, light as a feather and this makes barricades completely useless, giving the zombies an unfair advantage. They can just push down or pull out a mountain of objects down in a few seconds, that should weigh several thousand pounds.

The second way is changing the zombie_timer_max setting (which is how long until the first zombie appears after you can move at the beginning of each round), so that the first zombie appears almost instantly or too soon in each round. This completely ruins the experience, because the humans have no time to find a good spot and barricade themselves. Also, new players end up hating this mod when this happens because the round is over before they know what hit them, and they never get the chance to explore the maps, which are a LOT of fun if youre given the time to play them the way they were intended.

The authors of the zombie maps put all those objects everywhere for a REASON, to move around with your guns and barricade your self into areas, but a lot of servers are screwing the maps up in these two ways. It seems like most of the servers do this crap, and its really ******* me off, cause its ruining a GREAT mod that’s incredibly fun to play! When I can find a server that allows you to play the game CORRECTLY, then its tons of fun!

I think they're all doing it now, because I can't find a decent server. On every server I play, you only have enough time to buy you're weapons and find a spot, but not barricade it or set it up like the author of the map intended you to be able to do. You can only look at it, because a zombie is right behind you, then stand there wishing you would have had more time while staring at the spot you can't use. A lot of servers will say that the time they provite you until the first zombie spawns is plenty, but they don't take into account that a zombie runs much faster than a human player. So, they can quickly catch up to you.

I've also noticed that many people who can't play, who unfortunately are an admin are making up rules in this mod since they have no idea what they're doing. One of these rules is "tube camping". First of all, it's smart to "camp", because thats the entire idea of the game. You can't run away, you can only hide and stand you're ground. Whether you do it in a tube, in a room, or on top of a crate is no harder to reach for a zombie, if you know how to play the game. To reach a human in a tube, the zombies must form a line to keep the first one from being knocked back by bullets, alllowing him to progress forward and tag that human.

This would be a great mod, if servers allowed people to play the maps the way the authors intended them to be played.... but to be honest... these issues are really putting me off from this mod, and I'm looking for something else to play. I'm tired of admins whining cause they can't play and making up rules, servers with zombie_timer_max settings that are too low, servers that change the weight of objects so zombies can flick things around like soccer balls that should way several hundered pounds, players shooting down barricades, players blinding themselves and their team mates with smoke bombs, and the many terrible, glichy, half assed maps that are common on the zombie mod servers. I'm changing my score... the lousy gameplay has really ruined this mod for me. Plus with "No More Room in Hell" comming soon, why bother playing a mod like this with so many problems?
