Trial of the Sand Colosseum

Located in the desert, access this colosseum from the Desert: Center access point. Zoom out and locate the orange diamond-shaped structure to the right of your entry point. A machine guards the entrance, but it poses no threat. Completing this quest yields rewards, including the Destroyer Outfit (A2) for Rank S.

Gambler's Colosseum

Starting at Flooded City: Coast, follow the path towards the coast (the same path 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 1,000G to enter and begin the Gambler's Colosseum quest. The Rank S reward is the Revealing Outfit (2B).

Underground Colosseum

This colosseum is accessible only when playing as 9S. Begin at Forest Zone: Center. Follow the forest's left edge until you find machines training near a large waterfall. Pass through the waterfall to access the Underground Colosseum and its quests. The Young Man's Outfit (9S) awaits as the Rank S reward.
