It's almost obligatory to take this mission after finishing the previous one, because Delsin, despite unlocking a Video category, doesn't have any skills in it and can't switch onto different categories. Head for the first Core Relay in the northern part of the Lantern District. When you get there, watch a cut scene and wait for Reggie to unlock the access to the core. Draining energy from the core gives you the first Video power: Shroud of Invisibility. This power makes you temporarily invisible (L1 button). Check it out.
Follow Reggie who takes you to the haven in the northern west part of the Lantern District. Gain the energy from the core, so you unlock the melee attacks (Square). Notice that a group of DUP soldiers appear so you can test out your new powers. Launch the invisibility to approach enemies and then attack them using the melee attacks.
Remark: using the invisibility (and powers described later on) drains the power bar of Video. You can regenerate them by draining the energy from TVs, antennas and computers (blue dots on the minimap).
Delsin wants to head for the next Core alone, so you have to get rid of Reggie. Launch invisibility (L1) and then head off your brother. Try to hide somewhere after using the invisibility. After that Reggie should resign. When the conversation ends, head for the southern west part of Lantern District. Use attack to destroy the core's cover and drain energy to obtain Video Surge.
Video Surge is used for quick moving around. You have to use it for the first time in a moment because Delsin will be hunted down by several snipers. Use the wheel to launch it. Using it, you can easily get on the roofs, get high up in the air while next to the small antennas and fly in the air. For the time being, focus on using your new power to reach and eliminate each sniper.
Listen to the conversation and head for the northern part of Downtown, where you can find the fourth Core Relay. Use the latest power from Video Surge to get onto the skyscraper's roof (the one with flying demons) and destroy the cover of the Core Relay. Draining power from this Core gives you Bloodthirsty Blades.
This power activates after pressing R1. It requires Heavy Ammo. While using it, you summon three blades firing at the chosen target and dealing huge damage (if you miss, you waste ammo). Use it to take down helicopters. Try also be mobile to avoid rockets and, in case of need, get to the blue dots on the map to regenerate Video energy.
It's high time to head for another Core Relay which is in the southern west part of the Uptown. After draining energy, you unlock the standard attack (R2) Video Torrent. This power is identical with angel's attack which you know from the previous missions. But remember that you have to hold R2. Use this power and other offensive ones to deal with a group of DUP soldiers.
The last, sixth Core Delay is in the southern west part of the Rainier. When you get there, join demons fighting DUP soldiers and eliminate them. You can blow out the cover of Core and drain its energy. This gives you a special Video attack - Hellfire Swarm. To use it, you need proper Karma Streak, but it shouldn't be a problem for now on. Press the down on the D-pad and relax as all enemies will be eliminated without your activity.
Now you have another choice to make:
- If you play as a hero for Good Karma choose the mission 13a - Flight of Angels.
- If you play as a villain for Evil Karma choose the mission 13b - Hunting the Hunters.
