It seems that the bots in Left 4 Dead 2 come in all forms and sizes (mental capacity) and this one was one of the stupidest I've seen in a while. Thought I'd share this small clip that made me laugh while playing. Although I've seen some other stupid stuff by bots, I don't have many of them recorded.
Remember that L4D2 is on sale with Steam. I won't list the price because the sale probably won't last much longer and I'm sure they'll have more sales in the future. The campaign here is The Sacrifice and I play as a jockey, just watch as Francis pisses off the other player.
