Deathloop is a 2021 first-person shooter from Arkane Studios in which the assassin Colt Vahn is trapped in a repeating day on the island of Blackreef, learning its patterns until he can break the loop. The game's welcome-style framing became a natural shorthand for its central idea, and short audio clips from its trailers and menus have circulated among players who recognise the premise immediately. It remains useful because the loop concept travels well beyond the game itself, fitting any edit about starting over, learning from a mistake, or trying the same day again.
