Going through some swinging gas dispensers, Cole approached the generator, and re-establishing the circuit, he was granted Precision mode, allowing him to zoom in on enemies, allowing for a precise shot from far distances. He would have to use this new power on various objects and foes, such as batteries behind rotating turbines and Reapers behind turrets.
After fighting through the Reapers, he reached the substation and powered it up, restoring power to the remainder of the Neon District.
As you make the run to the substation, remember to stick to the high ground. If you have to fight any Reapers, make use of whatever powers you have gained so far. When you are in the sewer, after re-establishing the circuit, you will receive Precision, which you must to power up some switches that are far out of reach for Cole's Lightning Bolts. It is also going to prove very helpful against the Reapers you encounter throughout, as it allows for quick kills with shots to the head. To use to move, press and just fire.
