Trial of the Sand Colosseum

This Colosseum is situated in the desert. From the "Desert: Center" access point, look to the right (facing the direction you entered) 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

Located in the Flooded City, access this Colosseum from the "Flooded City: Coast" access point. Follow the path towards the coast (the same path used to guard the resource ship). At the end, find a waterfall and circle around the building to the left. A Resistance member guards the door; bribe them with 1,000 G to enter. Rank S completion grants the Revealing Outfit (2B).

Underground Colosseum

This Colosseum is accessible only as 9S. Start at the "Forest Zone: Center" access point. Follow the left edge of the forest to find machines training near a large waterfall. Pass through the waterfall to enter. Completing Rank S rewards the Young Man's Outfit (9S).
