Set in the immediate aftermath of the zombie apocalypse, Left 4 Dead's survival co-op mode lets up to four players blast a path through the swarming zombie hordes and terrifying mutant monsters. Guide your survivors across the rooftops of an abandoned metropolis, through rural ghost towns and pitch-black forests in your quest to escape a devastated Ground Zero crawling with infected enemies.
This is a mod for left 4 dead in which the infected sounds have been replaced with clips of pee-wee herman. The tank theme and the mega mob theme have also been replaced. With this mod all the common infected will quote and laugh like pee-wee herman. It is a delight, and a work in progress.
