Hit and Run is a simulant buddy that can appear in Perfect Dark's Co-op mode. He can be unlocked by completing the Carrington Villa mission in under 2:30 on Special Agent.
Hit and Run carries a K7 Avenger, and is a bearded man (resembling Grimshaw) in a Mr. Blonde overcoat. As his name implies, he will shoot at an enemy, dash away, and then shoot again. The distance he runs is increased when he is set to aggressive; when passive, he will still run after shooting, but will stay within the player's general vicinity.
