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.

Public Beta Overview

It has been a long and difficult road during the public beta testing period for this update. Essentially, the goal of the beta was supposed to be a major code rewrite to address the unfixable bugs from v3.0.9a which would be released as soon as possible. However, as time went on, we began work on a bunch of new features and game changes that would affect other areas of the game, especially regarding game balance. This, along with community and playtester feedback, made us realize how awful some things were functioning in the game, and that forced us to continue working on these issues for a while instead of shipping what was planned at first. That also meant more things to fix, monitor, and playtest, further delaying the release of 3.1 to the public, and even more minor issues had to be shelved due to complexity, necessity, or time constraints.

We've expanded this update beyond its original scope and we're sorry for this inconvenience. Hopefully, we can continue to focus on releasing frequent quality-of-life updates in the future, rather than holding off for a huge patch that could take many months to develop. We want to thank everyone who has supported us and helped us with the beta testing of 3.1, and everyone who has provided their feedback in the forums!

Lastly, here is the list of major changes we've made since the Beta 5 release based on community feedback:

  • The new character Larry has been postponed indefinitely due to voice recording issues.
  • Major adjustments to the recoil system for rifles and pistols, removing the static pattern (on-going).
  • Removed walking and running accuracy penalties. Jumping was moderately reduced. Crouching still improves your aim very slightly (untouched since release).
  • Refined the objective list panel, now it uses the O key instead of using the phone. You can now also walk and move while in this screen.
  • Removed the "Custom Server" tab that was separating community servers from vanilla and official servers if they were running any modified plugins.
  • Reduced ALL melee hit arcs slightly, preventing players from hitting areas that they weren't really aiming at (on-going).
  • All prop_door_rotating props in official maps have had their speed increased by 150 (default) and their breakable HP tweaked.
  • Various changes to player movement values, making movement smoother for both teams (e.g. climbing ladders is faster now).
  • New optional classic ammobank adapted for v3.1.
  • Reverted both Revolver and Remmy models and textures to the stock versions.
  • Added Characters Update by Mage and Silent.

Known Issues

  • Barricade hammer still uses the new system - we're planning to revert it soon.
  • [Linux] Users may experience their main game menu to be completely blank due VGUI.
  • [Linux] NVIDIA users with Nouveau might face few problems related to anti-aliasing (AA), causing a black screen. If you're getting this, please disable your anti-aliasing to fix this issue.

You can check the FULL list of v3.1 changes in our Changelog thread.



What's Next?

We've invested quite a bit of energy and time into other stuff behind the scenes that were put on hold during the development of the version 3.1 update, but there are plans for this content and other new features to be released to the public. We'll be sharing these features with the community in the near future, and we hope that you will give your input on what sort of new content should be added to the game by responding to community threads and public surveys!

In the meantime, enjoy the update as much as you can and be sure to tell us what you think in our Steam Discussion forums!
