NieR: Automata's 3C3C1D119440927 DLC unlocks three challenging Colosseums after receiving a mysterious letter. This guide details their locations and Rank S rewards.
Quick Links
The DLC introduces optional content and cosmetic rewards. The letter provides coordinates for three Colosseums, each with six increasingly difficult ranks.
Trial of the Sand Colosseum Location
Located in the desert, access this coliseum from the Desert: Center access point. Zoom out and look right (facing the desert entrance) for an orange diamond marking its location. A machine guards the entrance, but poses no significant challenge. Completing Rank S rewards the Destroyer Outfit (A2).
Gambler's Colosseum Location
Starting at Flooded City: Coast, follow the path to the coast (the same route used to guard the resource ship). At the end, locate a waterfall to the right. Circle around the building to the left, finding a Resistance member guarding the entrance. A 1,000G bribe unlocks access to the Gambler's Colosseum. Rank S completion grants the Revealing Outfit (2B).
Underground Colosseum Location
9S ONLY: Begin at Forest Zone: Center. Follow the left edge of the forest to a group of machines training near a large waterfall. Passing through the waterfall grants access (only playable as 9S). The reward for Rank S is the Young Man's Outfit (9S).
