Gears of War 2

After the third drop-off, your vehicle will begin to have some electrical problems at a very bad time, as three corpsers are about to surround you. As soon as power is restored, immediately target the three corpsers, starting with the one on the far right and working your way left (since they open up and become vulnerable in that order)—a shot each should do the trick. Oh, and try to do it quickly, otherwise it's Game Over.
