Try to use your newly acquired powers and you find out that you can’t do anything. So, you decide to meet up with Reggie in an alley. After some words with him, he decides to help you, so drain the Core Relay to get the power of Invisibility. However, this isn’t going to help yet, so follow Reggie to the next one.
This one will give you a melee ability, so use it in conjunction with Invisibility to take out the DUPs. Delsin calls Eugene to find him the next Core Relay, so head there and you’ll have to take out some Akurans. Once you do, open the Core Relay and drain it to get Video Surge, allowing you to move in the air and up buildings.
The next Core Relay will get you Bloodthirsty Blades, which are similar to Phosphor Beams and Cinder Missiles. Use it to take out the helicopter coming towards you from the left, then head to the next Core Relay, which will get you the ability to shoot normal shots with R2.
Take out the DUP Agents that show up, then there will be one last Core Relay to get. When you get there, DUP will be hanging around, but you will have the help of Eugene and his demons. Take them all out, then drain the Core Relay to get Hellfire Swarm, the Karmic Bomb for the Video power. Use it on the DUP that come and the mission will be over.
