I mentioned the hover board from this game in my Gears Post. Basically the game gives you a hover board that is only accessible in certain areas. Mainly because it would be too easy if you could out run every enemy and breeze over obstacles. That's not what bothered me. I really wished I was given a reason why I couldn't use it all the time that made sense in the context of the game. The Gears Hammer of Dawn explanation made more sense than the nothing this game gave you.
Also I hate AI partners and especially hate baby sitting them. Metal Gear Solid 3 was a good example, because you literally had to feed your companion. In Gears they were somewhat capable and only needed a pat on the back to be revived, but in enslaved your partner is a constant nuisance due to her constantly being in need of your help. On another note I had no motivation to help her, my avatar does, but I can't understand this. What happened is she puts a collar on your head that forces you to do what she says or die. I really didn't like the AI companion and I found it really frustrating that the protagonist seemed to do her bidding and take her ungratefulness in stride. Playing a game as a character who is forced to do something against their will and being submissive about it is depressing. It reminds of the indie game The Path, where you have to stray from a given path and have horrible things happen to you, with no reward other than that.
