Power Plant

Power Plant is a challenge in Risk of Rain 2.

Repair the broken robot with an Escape Pod's Fuel Array.

Choose any character other then MUL-T, unless in multi-player, and go to the back of the pod and interact with a panel on the back and remove the fuel array. It will now take the slot of the usable equipment slot. You must hold onto it until the Abyssal Depths level use the vents in the middle of the level to jump to the top most platform and walk over to the right of the last platform to a side platform that is slightly lower. Rex is quite visible, but he is the plant in the middle standing alone.
