The Sacrifice - Chapter 3 FinaleMake sure you select
Bill before starting.
After activating the 3 generators and getting on the bridge, you will need to run back and restart the middle generator.
The only problem you might have here is actually making it off the bridge in one piece. Make sure you have a
Pipe Bomb at the ready before you jump off the bridge. It's also important that you don't jump from too high a point as you will most likely have to retry due to the three tanks spawning at the same time. The best place to jump is on the right hand side of the bridge. There will be a mounted turret right here. This is where you must jump off. Once off, lob the pipe bomb and restart the generator.
