The 3C3C1D119440927 DLC, included in all editions, provides optional content and cosmetic rewards. Progressing the main game unlocks a letter containing coordinates for three colosseums, each with six increasingly difficult ranks.

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 poses no significant threat. Completing the Trial of the Sand Colosseum quest rewards the Destroyer Outfit (A2) at Rank S.

Gambler's Colosseum

Begin at the Flooded City: Coast access point. Follow the path towards the coast, the same route used to guard the resistance's 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 him with 1,000 G to access the Gambler's Colosseum quest. The Rank S reward is the Revealing Outfit (2B).

Underground Colosseum

9S only. Start at 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, but only if playing as 9S. The Young Man's Outfit (9S) awaits at Rank S.
