Zombie Panic: Source is a co-op oriented Survivor Vs Zombie multi-player survival horror modification for HL2. While our main priority is to make the mod as fun to play as possible, ZP:S plans to greatly expand on the core features of "Zombie panic" For HL1, with the obvious new features, impressive visuals, and of course atmospheric maps. More importantly ZP:S will not force players to fend against dumb and predictable AI, but instead keep the same intense thrill of surviving against intelligent and persistent player controlled zombies as the original.

We would like to start this announcement off by announcing our intended Full Release date: April 11th, 2014

Yes this means we plan to have Barlowe Square, Pioneer Express, All new mocap animations, all new sounds, new features, and a proper balancing and polish phase all done in roughly 1 1/2 months. This also includes an all new Main Menu/UI/Hud and sometime between now and then updated characters, each character with a complete voice set, localization for numerous Countries across the globe, and our Release Trailer plus quite a bit more.

All our hard work will start pouring out to those who already own a copy of the game and we will continue to release builds after Full Release which are not just the Free DLC we promised time and time again. The SDK will be released soon after Full Release and prior to release Server Hosts will have the options they require to host their servers as they wish (no ETA on Sourcemod/Metamod just yet but it is being worked on).

Today we released some significant changes and fixes as well as a new weapon and will continue to release new content and share via our social networks unreleased content more rapidly starting today.

"Early Access" Build 4366 - Changelog:

  • Fixed mp_roundlimit command so it now works
  • Adjusted spawning order for players, fixing spawning near same players each round
  • Fixed phone screen glitching when you or other players are on a ladder
  • Fixed nav-mesh commands to allow better debugging of the navmesh for broken areas
  • Fixed floating-roar glitch for zombies
  • Optimised update text loading to lower number of main-menu freezing issues
  • Added new Wrench weapon, first of the Kick-starter melee weapons
  • Fixed infection effects copying over to other rounds when not infected
  • Fixed crouch and jumping as a survivor stopping automatic weapon firing sounds
  • Fixed nail-gun looping sound and glitching issues
  • Adjusted overall spawning system for players, better and faster calculations, as well as more spawns
  • Zombie player jumping now limited by both stamina and delayed when taking damage
  • Optimised player think timers to alternate per frame, less server load
  • Added new, more detailed glass textures with the ability to shatter
  • Fixed missing player zombie sounds, zombie players to use same system as AI (Roar and Grapple)
  • Fixed GPS path sometimes not updating on dedicated servers
  • Fixed AI survivors missing sometimes missing when using GPS on dedicated servers
  • Fixed broken calculation of "Top Hunter"
  • Added new windows to Roanoke and Aurora
  • More advanced reverb system for weapon firing indoor and outdoor
  • Added fade effects when spawning and dying
  • More glass in RPD is now breakable
