This applies to everyone who owns the second game. The site has kinda dropped out over the last year. Competition from other communities, really lousy custom support, etc. The authoring tools for L4D2 are much improved. You can add zombie paths via Hammer, instead of recompiling the bsp. And there is a separate program for addon support. In short, the current TF2 staff have opted out. So I'm looking for some people interested in custom zombies, to help me bring the community back from the dead (no pun intended). Just send me a pm here or on Steam chat. And drop a line at this thread; http://forums.l4dmaps.net/thread-1092.html
