The basic idea of Zombie Panic! Source is to create solid game play that is based on a classic zombie outbreak scenario. The living dead are coming for the last remaining humans, and these survivors must fight them off and live through the day.


The game works like this:

At the start of each round, players can either choose to join the human team or volunteer to be the first zombie. If no one volunteers the game will pick one human randomly, and the game begins! The starter zombie's goal is to kill the humans while the human goal is to stay alive as long as possible, complete objectives, or even wipe out all the zombies. The catch is that when a human dies he will simply join the ranks of the undead, now ready to finish off his old living teammates. The humans can't tell by the player list who is alive and who is undead.

Eventually, there will only be one survivor still standing if everything goes wrong, his back against the wall while facing the animated corpses of his former allies. In a survival round, the zombies team only has a certain number of reinforcements (lives), and when a zombie is killed they lose a life from the counter. However, when a human is killed they gain 1 life. When the zombies run out of lives, the remaining survivors win the round by killing off the remaining undead left on the map. In objective rounds, zombies get an unlimited number of lives while the humans must complete a variety of map-based objectives to win.


Human abilities and advantages:

  • Speed - A zombie can only run at about 80% of the top speed of a human player. Though, the more weaponry and ammo a human picks up, the more it will slow him down, making him an easy target for the undead. If they are carrying nothing, a human can easily outrun a zombie. Watch out so you don't get cornered...
  • Weapons - The humans have a wide selection of weapons to use for defending themselves, like firearms, explosives and melee weapons. It is essential for humans to locate weapons and ammo around the map in order to survive, since they only spawn with a random melee weapon and handgun scavenging is a must. Remember that inventory space is limited and hogging weapons will merely slow a survivor down, so sharing with teammates is a must!
  • Numbers - At the beginning of the round, there are only from 1-3 zombies, depending on how populated the server is. Everyone else is a survivor. This means that they can easily watch each other's backs and provide cover fire. However, once their ammo starts to run dry and they begin to squabble amongst themselves for the few precious clips of ammo available...
  • Communication - Instead of typing messages to each other (occupying busy hands), which can be really dangerous when the zombies are lurking in the shadows, the humans have the ability to communicate by voice commands. There is a menu with several commonly-used commands that can help the survivors to organize a defense, trade ammunition and request help.

  • Panic! - Drop everything but what is in your hand and flee! This grants a temporary speed boost, allowing for a quick getaway, but use it wisely. More often than not, panicking just staves off a survivor's inevitable doom.

Zombie abilities and advantages:

  • Regeneration - Over time, zombies regenerate hit points, making it more difficult for survivors to make the undead dead.
  • Carrier - The first Zombie of the round differ a lot from the other undead - he looks different, sounds different, and has abilities that the average zombie can only dream of. He is the Carrier! With the power to infect people (10% infection chance per hit by default) he will cause panic and paranoia amongst the living. He also has the ability to roar, summoning other zombies to his aid
  • Persistence - Zombies might seem to die often, but they won't give up. They just keep re-spawning over and over until your pistol runs out of bullets, your back is to the wall, and there is no escape.
  • Numbers - Later on in the game, as the undead ranks swell with fresh dead, the last few humans will find their superior weaponry of small comfort for the hordes of zombies closing in.
  • Zombie Vision - Zombies can't use flashlights, so they have the ability to use Zombie Vision. Z-vision works in a way that it brightens up any possible light source in a room to make it more viewable. More importantly, when humans get tired, they start to glow blood red, making it easier for a zombie to track their prey. To prevent games of hide and seek a survivor who just sits still will also start to glow red through sheer terror of the unknown.


We want the mod to feel creepy and give you a sense of desperation, and yet not take itself so seriously that you can't laugh at the way you just died. Overall, fun and playability is the priority, and while realism and horror are important, those things are just a bonus when possible. We want a mod that you can easily play with groups of any size, even with small or uneven numbers. Plus, there's a certain sense of satisfaction in tearing apart those heartless survivors who failed to protect you while you were alive, limb from limb.


See you there!

Hello Everyone,
Our team has some excited and long-awaited news to share with you! After years of delays and putting the development on hold many times, ZPS on Source 2013 is finally happening!
Before we get into the details of what this will mean for the game, we must introduce our newest programmer, who offered to do the port of SDK 2007 to the latest Source Engine version SDK 2013, and is willing to support ZPS even more: Jonnyboy0719, from BrainBread2! He has been doing outstanding work porting this game to a proper build, fixing up lots of old bugs, issues and critical glitches from the old engine and making this happen for us!

So let's get to the news and what this means for the community.

Source 2013 was released awhile ago by Valve, and we were working on a port already back in 2014, which would be the release of ZPS 2.5 that never went further because of delays and other problems that the team had to face.

Now, with this new engine running on our upcoming build, we're excited to introduce the following:

  • Better optimization, fixed memory leaks and multi-core rendering, making the game run smoother, faster and more stable, for both players and servers.
  • Proper Linux support for dedicated servers.
  • Fixes of old engine bugs and glitches that were causing the game crash or close itself.
  • Better Hit-registration and lag compensation.
  • Better Steampipe.
  • Working achievements.

If everything goes as planned, we'll be releasing these features in ZPS v3.0, along with other improvements, as soon as possible. For now, enjoy this small teaser, showcasing the alpha state of ZPS 3.0

Meet Pedro: our newest Survivor!

Pedro was in development for a long time back in 2011, by our 3D artist EArkham. He's a ex-drug dealer from Mexico before the apocalypse started, and we'll make you guys finally meet him in-game sooner than you think! Here are some previews of what he looks like:

New Engine means major changes!

Since this is a totally new engine port, basically rewriting the game from scratch, Jonnyboy will be doing his best to make everything work how it is supposed to be working in ZPS. However, like we mentioned above, some things had to be changed, which will affect some custom content that was compiled for the Source SDK 2007.

This will affect all of the custom maps and content as they will in compatible with the new engine. The major changes on the port is a flip of the names/numbers that determine how your map reads the Teams (Human, Zombie and the Spec). Technically speaking, if any map running the entities: "filter_activator_team" and "func_ladder"; and was compiled in SDK 2007, it will be unplayable in ZPS 3.0 version.

But don't PANIC! yet. if you're reading this, are a community mapper and still active, then don't worry, the changes that have to be made are small and easy to do. We'll create a guide explaining how to do these small changes on your map, recompile it properly to be compatible and ready for the future release in no time! We're informing you now so that you have time to prepare but as we are not fully done with the build, other requirements needed to make maps work on the engine may be discovered. If so, we will inform you in due time.

New Upcoming Maps!

Speaking of maps, this update will include two old, popular community maps, made official: Zomboeing and FrozenHeart! Both objective, having lots of additional details and other changes that have improved the gameplay and look of the maps. We would like to thank Ratboy and Darb Dude for doing an amazing job on bringing back Zomboeing as an fully-fledged and incredibly entertaining experience!

And also, releasing bunch of maps improvements & fixes on other stock maps, introducing our first official Hardcore map, zph_pithole, by Xufe!

Improved Server Security - The days of malicious crashes are behind us.

One of the most important changes in this update is the solution to the age-old exploit that has been used to carry out server attacks for years. This behavior is not something we want to see carried over to the new build.

To help secure the community until the new build is ready, we've set up a Server Setup and Security threads. With the help of the community, their threads will help you secure your server to deal with the attacks to the best of the current engines ability.

When will this update roll out?

After all these information, you guys might be asking yourself: update, when!?
As we've mentioned, the build is currently in Alpha state, and our team is doing our best to bring you guys this update as quick as possible. The update is focused on bringing stability and security to the game, adding a bunch of new content is something our team wishes to do but we won't let it prolong the release date of this crucial update.
Future updates, that will introduce more new content and tweaks, will be shared with you as always through our announcements.

In the meantime, share these exciting news with your old friends through Steam, Facebook and even on Twitter! Tell them that ZPS is coming back in a more secure and stable state than ever seen before.
The next announcement will be the changelog of the ZPS 3.0 build. Looking forward to it! We sure are.

And of course, the port over to Source 2013 is a fantastic step in this Mod's direction and opens up new opportunities in the game itself; I'm more excited to be receiving a new character after such a extended while, but all in all, thank you for your contributions to this Mod after so many years Community Members.

Hopefully monochrome will have the sense to go back to it's roots and make a zombie panic standalone, maybe for source 2? As long as they keep it similar to zombie panic it'll be a hit and all the old zps players will return :')

Still playing this classic mod. Still a few servers out there, but not nearly as many as there were when it was first released. Such nostalgia. I'd like to see a remastered version of Zombie Panic.
