Trial of the Sand Colosseum Location

This Colosseum is situated in the desert. From the "Desert: Center" access point, look to the right (facing the desert entrance) for an orange diamond-shaped structure. A machine guards the entrance, but it poses no significant threat. Completing Rank S rewards the Destroyer Outfit (A2).

Gambler's Colosseum Location

Located in the Flooded City, access this Colosseum from the "Flooded City: Coast" access point. Follow the path towards the coast (the same route used to protect the resource ship). At the end, locate a waterfall to the right. Circle around the building to the left to find a Resistance member guarding the entrance. A 1,000G bribe unlocks access to the Gambler's Colosseum. Rank S completion rewards the Revealing Outfit (2B).

Underground Colosseum Location

9S ONLY: This Colosseum is accessible only when playing as 9S.

Starting from the "Forest Zone: Center" access point, follow the left edge of the forest until you encounter machines training near a large waterfall. Pass through the waterfall to access the Underground Colosseum. Completing Rank S rewards the Young Man's Outfit (9S).
