- Bombing Run — Bombing run can best be described as Unreal-style American football where the player with the ball has to take it into enemy territory and score in the enemy force's goal. Players can pass to other teammates. Getting killed causes the ball carrier to fumble the ball. The ball launcher is used to carry the ball; it is not a weapon but heals the carrying player when they are at low health. Three points are awarded for field goals (shooting the ball through the goal), and 7 points are given for touchdowns (carrying the ball through the goal), although the levels are often designed such that this kills the ball carrier.
