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.

I want to start a fan group of this game if any one wants 2 add me so we can start a group.
Is this still getting development or has it stopped? Haven't played it for quite a while. Is there still anyone playing it?
Yes to both. Development is still going, and going well. Of course there are still people playing. Hope you enjoy :)
poop double post
Is 2.2.1 on desura? Because my steam version crashes on startup and my desura download is 2.2 a.k.a I can't play with anyone....I can't manually patch it because its just steam and desura...
Hi there. Really like the game, have had it installed for a few years now. I'm just wondering, other than fixes and updates, are there any big game changer type patches coming?
Any new classes / guns / zombies / abilities / objectives that we can look foward to? I was really disappointed when the ability to move a lot of the furniture was removed (even though I understand why) but that removed a SERIOUSLY large part of the dynamic and fun for me. This game has a lot more potential - just wondering is there anything in the pipe line or is this as advanced as the mod will get aside from hotfixes? Many thanks for the game, your efforts and any replies. Best of luck. Gary
We definitely have some big stuff planned
you copy it from steam -_-
