Maybe the best example of the living battlefield comes in the form of the civilian vehicles lining city streets—they aren't just decoration, but are also fully operational for your commandeering pleasure. Drop a machine gunner in a truck bed and hit the road. Or you can just blow the vehicles up to take out opponents seeking cover behind them. Should you shoot the cars, you can marvel at the detailed physics engine behind the realistic way the autos rotate and bounce on their shocks when shot—right before you plug your ears from the ensuing, inevitable blaring car alarm.
