Trial of the Sand Colosseum Location

Located in the desert, access this Colosseum from the Desert: Center access point. Zoom out your view and look to the right for an orange diamond-shaped structure. A machine guards the entrance, but it poses no threat. Completing Rank S rewards the Destroyer Outfit (A2).

Gambler's Colosseum Location

Start at 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 your right. Circle around the building to the left, finding a Resistance member guarding the entrance. Bribe them with 1,000 G to enter and begin the Gambler's Colosseum quest. Rank S completion grants the Revealing Outfit (2B).

Underground Colosseum Location

This Colosseum is accessible only as 9S.

Begin at the Forest Zone: Center access point. Follow the forest's left edge until you find machines training near a large waterfall. Pass through the waterfall to access the Underground Colosseum. Achieving Rank S unlocks the Young Man's Outfit (9S).
