Left 4 Dead 2 Demo — Tank vs Bilerate

*Bilerate is a reference to the jarate — jar based karate from TF2. This weapon is actually called bilejar, it's an injection with boomer's bile. This video demonstrates how an infected crowd can kill the Tank and he won't do anything about it. The Witch, however, will attack zombies if they are attacking her. I dunno if it is bug or not...
