Elden Ring Nightreign is a cooperative spin-off set within the Elden Ring universe, reworking its combat and exploration into a session-based, roguelike structure focused on repeated runs against escalating threats. Teams of players face off against powerful bosses under time pressure.

Its shift toward shorter, replayable expeditions distinguishes it from the sprawling single-player structure of the original game, while keeping the weighty, demanding combat that defines the wider Elden Ring world.
