Zombie Panic! Source is a standalone cooperative, survival-horror, first-person-shooter! Set in the middle of a zombie apocalypse, players start as a small group of survivors attempting to stay alive. Each map will have its own objectives to complete and win the round or survive by a period of time.

RSS v3.1 Beta is now available for public testing!

The major beta update features new animations, models, weapons, sound and particle effects, and much more! Including the long-awaited Linux client support. We're enthusiastic to hold one of the first ever open betas for Zombie Panic Source! This gives players an opportunity to test, provide feedback, and aid in reporting bugs for new content before it officially releases.

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!

Hell. Yes.

How do I start a local server with bots in 3.1 unstable? I set Enable bots, but in game I cannot even go to console, it won't appear when I toggle it. Or is there a different way to add bots?

The bots are not intended to be fully functional, they are only for testing purposes.
They don't even have a working AI though.

1) Set the toggles in options (Options -> General -> Keyboard binds -> Advanced -> Show console)
2) zps_solo, sv_testmode, bot_zps_add_human/zombie are your bread&butter;.

If you want to create testmode server for friends to join:
1) sv_lan 0, then
2) changelevel (any level)
3) status (get your ip)

Your friends should use
connect <IP> (without brackets).
