Left 4 Dead 2 DLC The Sacrifice Finale Gameplay (Bill's Death)

After long anticipated wait...ITS HERE. Here is a gameplay of the Finale with a random group shortly after downloading. The campaign was pretty straight forward. At the end, I remember hearing about generators that need to start up. After the hitting the switch on the bridge, the bridge itself stops halfway and Zombies will keep coming as well as those 3 tanks behind them. I knew then, that was my cue.... Bill Forever!
