NieR: Automata - Mysterious Letter Guide

NieR: Automata's 3C3C1D119440927 DLC unlocks three challenging Colosseums. After receiving the Mysterious Letter, you'll need to locate these arenas to earn unique rewards. Here's a guide to finding each:

Quick Links

Trial of the Sand Colosseum Location

This Colosseum is located in the desert. From the "Desert: Center" access point, look to your right (facing the direction you entered from) for a distinctive orange marker. A machine guards the entrance, but it won't pose a threat. Entering initiates the Trial of the Sand Colosseum quest.

  • Rank S Reward: Destroyer Outfit (A2)

Gambler's Colosseum Location

Begin at 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 your 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 gain access and start the Gambler's Colosseum quest.

Underground Colosseum Location

9S ONLY: This Colosseum is accessible only when playing as 9S.

Start at the "Forest Zone: Center" access point. Follow the left edge of the forest until you find machines training near a large waterfall. Pass through the waterfall to access the Underground Colosseum and begin its quest.
