Double Dragon IV is a beat 'em up video game in the classic Double Dragon series, developed by Arc System Works. Released for the PlayStation 4 in 2017, the game serves as a sequel to the original arcade trilogy, taking place shortly after the events of Double Dragon III. Capitalizing on the nostalgia of the '80s arcade era, it offers a new story and gameplay in the same retro aesthetic, featuring traditional side-scrolling mechanics, a variety of combat moves, and two-player cooperative action.
