Crystal of Atlan x NieR: Automata collaboration runs May 21 - June 18, 2026. Features new Karmaslayer class, NieR-inspired cosmetics, and Battle of Grün world boss event. The collaboration brings outfits and weapons inspired by 2B and 9S from NieR: Automata into Crystal of Atlan, letting you bring the YoRHa aesthetic into the game’s world. If the idea of running through Atlan in 2B’s outfit is enough to get you to log back in, NVS Games is very much counting on that, and the cosmetics look sharp from what has been shown so far. The bigger gameplay addition is the Karmaslayer, a brand-new class debuting as part of the collab.
