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.

Going to ever let us play this without having to install the dedicated sever, which is wasted space for those of us that don't want to host them?
Everytime I go to download this, says 1600MB. However, once I click it, it starts downloading both the game, and the dedicated server, quickly taking up more space.
IF I stop the Dedicated Server download, the ZP:S one stops as well...if I stop & delete the Dedicated Server, I seemingly delete ZP:S as well.
If I let both download to completion, then delete the dedicated server, it deletes ZP:S as well.
This is the only Steamworks mod doing this to me and it's frustrating.
I realize this is probably a fault on Valves end....but still frustrating as all heck...wasted bandwidth, wasted HDD space.
Is it due to the .gcf format?
Cause like I said, Age of Chivalry doesn't suffer from a problem like this...
Anyone hear anything on the next patch?
@Dakcenturi the team just released a small patch to fix some bugs and exploits:
=====2.2.1 (02-27-2012) =====
+ Fixed Infected Bug.
+ Fixed some cases of BunnyHop.
+ Fixed joingame exploit.
+ Added filter support for game_zone_player
Oh, moving onto Source 2?
Congrats. It's a really nice upgrade. Source continues to look better and better, but the hardware requirements stay the same. Feels good.
To clarify the information that's been posted in the zombie panic news section, Tatsur0 and his Contagion team are the ones who are talking to Valve about that
ZPS on the other hand, we're staying on Source SDK Base 2007 so don't get your hopes up on a drastic engine change lol
I just tried to access the www.zombiepanic.org web site and it tells me "This site has been suspended"
I also tried to access the forums via my bookmark and I got:-
Forbidden
You don't have permission to access /forums/index.php on this server.
So whats this all about?
I think they are changing server hosts.
want it for linux64!!
Please add support for steam version installer, if possible:)
Appreciate all the support but we didn't make the cut but it was close. I believe strongly that 2012 may in fact be ZP:S's year :D Contagion did however make it in the Top100 for IOTY and we'd very much appreciate the support :)
