When your characters first reach the ferry station, its occupied by a bunch of prisoners. They're friendly at first, but then they immediately demand you hand over all of your possessions, and attack. Shortly after this, you then enter an extended rage mode, and can promptly kill them all with no problem. This is due to your exposure to some chemical weapons moments earlier while working your way through some old tunnels to get to Henderson. It reacts to the virus in your character's body and unlike poor Wayne, makes you nigh invulnerable instead of a hulking mutant.
It's not just an extended rage mode, you go completely and totallyape shit. Blood lust, Cluster F-Bomb, your character quite likely not stopping until everyone in Henderson is dead had it not run out, their little freak out when it does, the whole nine yards. A crowning moment of scary awesome.
