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.
Replaces sound files of the Hunter with phrases from Mario and sound effects from the Nintendo 64 generation of Mario games such as Mario 64 and Mario Kart 64 as well as some classic sound effects from the NES generation to fill out the package. Almost every single sound is replaced except unused Hunter sounds.
If you're wondering why it says "It's a me mario" so many times in the video preview is because the survivors are killing many hunters and I'm spawning them constantly. Those are the sounds they make when they spawn. So far I've eliminated most of the noise and it should play smoothly in regular games. Although it is a little less alarming to hear "Ahh mama mia", beware, hunters are still just as deadly as they were before, except now they have an audio applied poor Italian stereotype about them.
