yep it does work in vs, i showed 3 of my friends, and we invited friends to be infected, by the end, they all were saying they didnt want to be our friends, and that we didnt deserve to play with them, then when we all got to da choppa alive, they rage quit....alltalk was on...they were literally screaming at us and we were laughing sooooo hard...best l4d experience ever... B T W, i found an additional exlploit.
~ BECAUSE the tank cannot get to u, it becomes an NPC that will charge in after the player loses the control....if u stand in the right spot...he falls through the elevator shaft and dies....easy as pie...not one of us took any damage from 2 tanks and all those mobs....and i dont know of any sites, this is a result of me and my friend hitting a minigun for 4 hours, Enjoy
~Each gun exploit is EXTREMELY different.....every place you hit it will send you in a different direction, if the hits are even one centimeter off of the target you will shoot either straight up, or off the building, or into a wall....there is also an exact number of bashes to do, its a extremely involved process :P
