Well I rented it a week or two ago as I had a free rental and the games I wanted were out.
Its decent. It feels like an uncharted copycat in some senses, and not just do to voice acting. There is bascially the same set of characters, etc. Some of the enviroments reminded me of Uncharted as well.
The rocket pack thing is ok, and the story is pretty cheesy. There were a few glitches I ran into and it was annoying. I had come to the last 2 chapters and I had about 2 left I presume.. It came down to be sleeping for 5-6 hours or beating the game and sleeping for 4 hours or so the last night I had it.
I just went to bed and returned it the next day. I would normally not do that, but the game was really not keeping me into it enough to stay up.
I am guessing this is going to drop really fast.
