Left 4 Dead Content?

http://l4dmapdb.wikidot.com/

^^ A good site about user made mods for Left4Dead. This game is going to have a HUGE mod community it looks like. As for Valve im not sure when they will do there own add ons, but im fine with user made content until then.

*Also this one aswell http://www.l4dmods.com/*

I think we'll see a Nice Boom of Mods when the SDK become available,

the most people can do at the moment is Maps.etc, but we need the L4D SDK be able to do any big time Mods

User mods are what is going to make L4D shine ... ther are already insanely cool levels being developed and since the program used to decide where zombies spawn (cant remember the name) is adaptive it easily fits into any custom level. So expect to see some insane levels and mods appearing soon from users.ColdfireTrilogy

Wait..so if it is a custom system thats kind of lame that we didn't get a few more campaigns..
