Armored Core 6: Underground Exploration - Depth 3
Below you'll find an overview of the Main Mission called Underground Exploration - Depth 3. We'll provide a brief Walkthrough, an Objective Log, details of any Collectibles, and any additional information you might find useful.
Having cleared Depth 2 and beaten the Enforcer (tough, isn't it?), you'll be onto the final layer: Depth 3. Head through the blast doors out of the boss arena and take the detour through the rocky area and you'll catch your first glimpse of the reactor. Drop down onto the walkway, then use the metal for cover to get around the laser snipers. You can then drop down below the reactor to follow the objective marker.
You'll eventually come to a set of blast doors. Open them, follow the path to the right, then enter the chamber and destroy the mechs inside. Interact with the next set of blast doors, follow the path to the right, then destroy the target. You must now quickly go back the way you came as the reactor explodes. However, once you enter the previous chamber, the door will shut and you'll need to beat Ephemera. Now under a two-minute time limit, quickly dispose of the boss by being very aggressive with your melee attacks and filling their stagger gauge. Once they're dead, continue your escape.
Follow the objective markers outside, and a cutscene will spell the end of the Mission once you get to safety.
