Do you have any idea what SourceMod/MetaMod is capable of with L4D1/2?
Points system,
barricade mod,
Buy system,
5vs5, 6vs6, 7vs7 etc Versus/Scavenge,
5-28 players Coop,
various edits to special infected,
stuff like a proper director that actually adjusts the zombies on how many people play/how you're doing. No, the vanilla one does not do that.
