A first-person view of a player moving through a dimly lit industrial corridor, firing a weapon that emits green laser beams and causing an enemy to explode in a burst of orange light, then transitioning to a different area with a large green energy shield and a weapon with a glowing blue barrel, before the screen cuts to a scoreboard showing team rosters and a separate clip of a bald man in a suit shouting in an office.
