The basic idea of Zombie Panic! Source is to create a solid gameplay 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 a 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 hiding and seek a survivor who just sits still will also start to glow red through sheer terror of the unknown.


We want the game 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 game 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.

Holy crap, I had no idea this was still being updated. I used to be super involved with the forums way back in like 2009, making maps and stuff. Maybe I'll download ZPS again and see if people are still playing on Cabin. The worst map.

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.
