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.

Today, we're very proud to release the 3.1 update for public playtesting! The latest changes are all available in our unstable beta branch. You can find out how to opt in to the beta on this thread.

We've created a new sub-forum in our Steam Discussions for reporting bugs and providing feedback during the public playtesting period. All of 3.1's issues, crashes, suggestions, and ideas should be directed to that specific sub-forum only. Please keep everything 3.1-related in that forum for better documentation and organization.

The following major changes are:

  • Linux Client support working for Ubuntu and SteamOS versions.
  • New recoil system, similar to Day of Defeat: Source, for each firearm.
  • New survivor's first-person and third-person animations for pistols, shotguns, rifles, explosives and phone device.
  • New sound effects, three new melee weapons, and a brand-new explosive grenade model.
  • New portable inoculator for self-heal, healing your teammates or delaying the infection (depending on the color of the inoculator)
  • New sprays from our community contest winners and development team.
  • Source code rewritten from the ground up without using any of HL2DM's code.
  • Improvements to player hitboxes and barricade hammer enhancements.
  • Biotec redesign with visual improvements and Club Zombo gameplay improvements.
  • Steam Workshop fully functional again with additional "Add-ons" menu.
  • A new 'tutorial' menu section dedicated for newcomers.
  • Glock 18c is now a fully automatic weapon, but is much more inaccurate than other pistols.
  • Updated ZPS Angelscript API documentation.
  • 30 new Steam Achievements.
  • Numerous bug fixes!

IMPORTANT: to have the new sounds work properly, you will need to remove your sound cache in your vpks. Delete the "zps_sounds.vpk.sound.cache" file located inside your vpks folder inside your Zombie Panic! Source directory.

We highly recommend backing up your personal client files before opting in to the beta in case something untoward happens. We appreciate your help in advance!

I guess you have heard about the fake HL email news right? So i just wanted to say:
"You know, even if it is a fake i still didn't give up hope
At least we still have: Operation Black Mesa, Guard Duty, Project Borealis, Boreal Alyph, HL2 MMod, Black Mesa + Xen, HL VR, Back 4 Blood, Peer Review & Decay Source and many others. Who knows what's gonna happen in the future? i won't loose hope, never."

And like i said before:
"All of you are our hopes to keep the Half-Life series "ALIVE", so please don't give up".

The destiny of the Half-Life series right now is in yours and our hands so let us all be together and wish and hope for a better tomorrow.

It will always be PvP (Human players vs Zombie players). However, there are servers who host against BOTs with modified plugins. Plus, you can solo test mode by adding BOTs (but they don't have actual AI).
