Was hoping for the powers they teased us, and after all that work doing the paper trail it feels even worse. Maybe her neon is different than Delsin's, so if they build her powers better and add more things to do it might be good.
But I would have prefered a nice DLC with 3 extra powers, more missions (engaging ones) and more enemy types to fight against. User generated content should make a comeback. I don't see the point in having all these powers if, by the time you max them, you practically have nothing to use them on. USG solved that in IF2. I would gladly pay for something like that. There were a shit ton of bad missions, sure. But there were very good ones as well. Besides, you could easily create any kind of crazy situations for you to try your powers, from semi-civil wars between enemy factions to melee gauntlets against infected, to mini platforming sections (there was one someone made that had a tower maybe 2x the size of the tallest building in New Marais).
Even though the powers (at least one) should have been offered for free as a reward for completing the paper trail. Even though this might help flesh out Fetch's story and personality, I think they should have done this in the main game. Characters come and go and barely get any exposition, apart from delsin's relationship with his brother.
But don't worry cause they're now releasing it for you to pay! This is what I don't like.
