Note! Selecting this mission is recommended only if you follow the path of the hero, i.e. you strive for amassing good karma. It is worth knowing that starting this mission lock access to mission 17b (Kill Augustine), which has been prepared with playing, as the bad character, in mind.
The starting point for this mission is on the rooftop of a building in the Uptown district, to the North of the D.U.P. main tower. Make sure, however, that you have approached the correct marker, because the one connected with the Bad Karma mission is right next to it. After you start the mission, start by sabotaging the generator (slide your finger down the touchpad) and start firing from a safe distance, aimed at the enemies that are patrolling the balconies below, around the central building. You should especially watch out for the snipers, try to eliminate them in the first place and hide behind the generator, or the other covers, if necessary.
Do not haste too much to reach the D.U.P. skyscraper and try to eliminate as many soldiers, at a long distance, as possible. Only then, start switching into smoke and hovering in the air (the Smoke category), leaping off the roof (the Neon category) or perform a standard flying (the Video category). Depending on your preferences, you can now encircle the building and eliminate all of the remaining enemies that stay on this level, or turn to the shaft shown in the above screenshot, which has been unlocked after the generator has been destroyed. To use the shaft, you need to activate Smoke power.
After Delsin is catapulted, turn into smoke (the circle) at the right moment and access the other shaft to reach a balcony above. You need to get to the neighboring platform. Wait here for Fetch to appear and seize the situation to obtain the shard shown in the above screenshot, which used to be inaccessible, during the free exploration the Uptown district.
Wait for Fetch to unlock one of the nearby shafts for Delsin and press be circle, after you reach it, thanks to which your character will be catapulted. After you land onto the balcony above, be prepared to square off against another group of D.U.P. soldiers. During the fights along your path to the top, it is a good idea to use smoke power on a regular basis. You do not need to save it up, because you will be encountering chimneys, and the other interactive elements of the surroundings, thanks to which you will be able to regenerate your powers.
Again, you need to wait for Fetch to use her powers to unlock access to the shaft here. This time around, you will have to perform a bit harder task, because you need to leap towards the vertical element of the structure, shown in the above screenshot. After Delsin is catapulted, start rising up in the air and turn into smoke, while attempting to grab onto the first interactive ledge. Now, start jumping towards those of the ledges that are located above and finally fly towards the stable ledge.
Here, you will have to defeat a small group of D.U.P. soldiers, which you should not have too many problems defeating. It is a good idea to take, to your advantage, the fact that Fetch is using the Stasis Bubble and either to attack the armless enemies trapped in the bubbles, or use the fact that they cannot attack Delsin and fire at the other enemies. After Fetch has unlocked another shaft, run up and launch yourself into the air, towards the vertical structure that you can see in the distance. Climb to the very top and fire at the enemies at a longer distance.
Glide towards the next platform, after you get under fire again. You need to watch out here, because Delsin will not be able to use covers at first, and many of the enemies are using quite powerful abilities. Therefore, you should fire Cinder Missiles on a regular basis, thanks to which you will eliminate the opponents much faster. After you have eliminated all of them, find a new shaft in the skyscraper's wall and use it to reach the site where you fight a larger battle.
This fight, with the D.U.P. soldiers, is much easier than it might seem at first, because apart from Fetch, also Eugene, angels and demons summoned by him, will lend a hand (Eugene will appear in the form of the huge angel that you have seen before). In the initial phase of the fight, focus only on the elimination of the nearby soldiers and only after you have dealt with them, attack the enemy choppers. The good news is that the flying machines will by busy attacking someone else so, you do not need to fear their missile fire.
After you have eliminated all the soldiers, and brought all the choppers down, stop in the position shown in the above screenshot. Leap towards the vertical structure and reach it by flying up to it and changing into smoke. Climb to the very top, jump onto the ledge and fire at the elite enemy, who is occupying the ledge below (use the advantage of height and aim at the ammo boxes). After you have cleared the area, jump onto the neighboring balcony (leap off the shaft) and follow Fetch.
Follow Fetch's suggestion and switch the category of your powers. Approach the nearby antenna and press the touchpad, to drain it for energy, and activate the Video category. You can now use the Video Surge (Circle), as you run, to reach the skyscraper's rooftop. Start attacking the D.U.P. soldiers here (You can still count on Eugene for his help), and deal first with the characters that are close to (the armless) Fetch. After you win the fight, jump off the antenna (Circle) thanks to which you will reach the atrium, where you will fight the final showdown with Augustine.
