Level powers: of course it is the neon was the ISS power I had preferred so I was glad to find it in this DLC.
The special power (activated with one button at bottom) is not the same as Delsin. The both of them are extras.
Important point to address: the existence of a battle mode. There are actually 3 Arena and two battle modes (save hostages and survival).
If you played ISS you can play in the arena not only as Fetch but also as Delsin (so we can use all the powers of Delsin, smoke in concrete).
2 only flaws I blame the game:
- Lack of choice / no karma bar.
- The life of the story too short; Fortunately there was the arena to let off steam!
