Requiem comes from ULTRAKILL, the fast-paced first-person shooter known for its intense combat and striking soundtrack, and it has become a favourite among players sharing clips from the game. Fans use the track to give their videos the same sense of judgement and finality suggested by its name, especially when a hard fight or a decisive moment is on screen. As ULTRAKILL edits spread across short-form video and gaming communities, the short clip became a shorthand for high-stakes action, which is why creators still reach for it today.
