Someone has figured out a way to host 16-player co-op in Left 4 Dead 2 on the PC, and as this video shows, it is pure mayhem, with survivors outnumbering infected during some parts of the game.
Plus, I mean, god damn, look how long it takes for everyone to get in the safe room.
Here's another video. I love the beginning, everyone running one after the other to the weapons table. As awesome as this looks, I bet it's pure hell to play. We're seeing the reason Valve capped this at four to a side, I think.
