Announcements _

We've rolled out the third patch for Zombie Panic! Source v3.1 - focusing on achievement fixes, client and server crashes, game balance and map adjustments, bug fixes, and more! Server owners must update their servers to receive the latest changes.

Highlighted Changes
New ZP Options
We've added more Zombie Panic! options based on community feedback regarding the number of door & player gibs, and the ability to toggle Zombie Teammate glow and objective notification displays. We will also be adding an option to adjust the color of the classic ammo bank in an upcoming patch.

Be sure to double-check these options and others you feel could improve your gameplay in Game Options > Zombie Panic! Options > Misc.

Game Balance
With the release of today's update, players will notice improvements to the Survivors' arsenal with respect to Shotgun spread, base damage, and damage drop off - to be more intuitive and more reliable. The Magnum has been nerfed with an increase in its damage drop off - requiring a Normal Zombie to be within about 680 hammer units distance to be killed with one headshot.

Movement speeds have received adjustments in order to better balance them. Survivor walking and panic speeds have been made slightly faster, and stamina regenerates slightly slower. There will also now be a delay before stamina begins to regenerate after pressing walk or crouch. Zombies Feed-O-Meter will regenerate faster now. Normal Zombies also got a slight boost to their base speed, to keep the Carrier from outrunning them too much.

Several official maps have also received significant balance changes. We'll continue making more tweaks based on your feedback!

Voice Proximity
This feature has been requested by a few people in past years and already implemented into the game in v3.0 for Hardcore mode. Some people would prefer to hear voice communication based on your location rather than listening to the whole team everywhere. Therefore, we decided to build on the existing option and create a separate CVAR command for server owners to set voice proximity in their servers without enabling Hardcore mode.

Now let's dive into the full list of changes below!

Update Notes
  • Added new "CBreakableProp" class which is a child of "CBaseEntity".
  • Added "CBreakableProp.SetBreakable( bool state )" to set breakable state on props.

Don't worry, we still will be accepting feedback and working at a slow pace during the holidays, and afterwards beginning to release monthly patches more consistently.

Happy gaming,
Zombie Panic! Team
