Quick Links
The DLC introduces optional content and cosmetic rewards. Each Colosseum features six ranks with progressively tougher enemies.
Trial of the Sand Colosseum Location
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 poses no significant threat. Completing the Trial of the Sand Colosseum quest rewards the Destroyer Outfit (A2) for Rank S.
Gambler's Colosseum Location
Starting from the Flooded City: Coast access point, follow the path to 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 of the waterfall to find a Resistance member guarding the entrance. Bribe the guard with 1,000 G to enter and begin the Gambler's Colosseum quest. The Rank S reward is the Revealing Outfit (2B).
Underground Colosseum Location
9S ONLY: Access this Colosseum as 9S from 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 enter. Completing the Underground Colosseum quest grants the Young Man's Outfit (9S) for Rank S.
