Power High is a challenge in Ardorton Station that requires players to disable an electric force wall in order to open a loot chest. These are most often found by following the cables.
The compartment is located directly in the center of the map. As you turn to the north you can hear the electric force wall to your left.
The switch to disable is in the bandit camp to the southeast of the compartment, up the large flight of stairs and then up smaller stairs to the right.
