The APS Underwater Rifle is an underwater assault rifle that appears exclusively in Call of Duty: Ghosts single-player. It appears in the missions "Atlas Falls" and "Into the Deep", being used by Logan Walker, Keegan P. Russ, Thomas A. Merrick and Kick. Unlike other guns, the bullets will take time to hit their targets, rather than hitting them instantly, due to water slowing the bullets down. They will also leave a trail of bubbles.
