Speaking of which, is kiting Tank spawns back to spawn legal (forcing AI tanks...)?
We've decided the rules in L4D1 regarding AI tanks were too ambiguous and became hard to police, most of the L4D1 community now understand the various tank spawns on every map after playing for so long, but with L4D2 being a new game and with most teams never playing confogl, we've decided to make the use of an AI tank legal, as well as infected attacking with the AI tank. Survivors can force the tank AI if they wish to lose the distance but there is no onus on the tank to keep control and infected can setup attacks around this. Teams are still required to tell the other team that the tank is AI.
@Randomtask, Sorry I accidentally originally edited your post, admin fail.
