My L4D2 have so many mods that it hardly resembles L4D2. Tanks is Kool-Aid and Survivor are MGS low-poly Snake, Rayman, RE5 Jill and a soldier. Also all zombies are skeletons, Charger is Dio (with another mod to have a rainbow effect left behind), Boomer is Robotnik that even scream "Pingas!", Spitter is Kazooeie and a lot of items are custom too, like Zero Saber, Bob-omb, Soda cans, some posters are Sonic, Final Fantasy fanfare when you enter the safe area... xD
