The first boss battle with Marcus Black is awesome, too. You shoot out the tires of his truck, causing it fall over and cause a wreck. Then he shoots out of the truck and says, "You want it? Then come over here and... Take it!" Then he uses an anti-tank rifle against you during the fight. Cue some awesome guitar riffs, boss fight and Stuff Blowing Up.
The Stage 2 boss battle with Jack Mathers. It ends with Captain Rush delivering an uppercut to Mathers, and a boxing knock-out bell during the stage clear screen.
