v3.1 Beta is now available for public testing!

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.

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.

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!
