sentences:  Another player can serve as Co-Pilot/Gunner (CPG) for each side.The CPG has a targeting reticle used to fire off-center at targets of opportunity.The targeting reticle does not remain stationary relative to the player's ship, but stationary relative to the surroundings, which means that it races to the edge of the screen as soon as the player's ship makes a turn, if the CPG does not compensate.
