What do you do when you're a multi, multi, multi-million selling war simulation video game franchise looking to stoke the fires of hype before your latest big release? You bring in an Olympic champion swimmer, obviously.
Starring in the latest live-action trailer for the much-vaunted Call of Duty series Michael Phelps appears as a civilian sent to space, where he shoots some guns and stuff... we're not sure why either.
Speaking to TIME about his latest role outside of swimming really fast, Michael said: "I do play the game a fair amount… maybe sometimes too much. But it's always great, talking trash and getting a little friendly competition in there."
Call of Duty: Infinite Warfare is released 4 November.
