Left4Dead: Swamp Rage! (With Dino and Alien Mods)
Check out an epic vs. mode match in the classic Left4Dead campaign Swamp Fever! One of the players on our team out ran the tank and all the infected with practically no health, making it all the way to the sanctity of the safe room.
Some cool mods included as well, including the Velociraptor Dino and Alien mods.
