It is a pretty challenging game, yes a few things are a little broken. But it's got a good story and a lot of stuff to do. I actually enjoyed the gear system, because you have to constantly adapt to your enemies. The stealth aspect is amazing, and it can get pretty intense when your trying to sneak around people or robots. To me this game is worth about 4 stars. I hope they add more to the game and fix certain bugs that are in the game. But that will only happen through time.
