This is a good cover based shooter, but not exceptional.
The graphics are good, the cover mechanics are good, and I appreciate the story and dialog-based elements.
A few things prevent it from achieving a higher score. First, your motion is highly limited. You can jump from core to cover but cannot freely move around. I dont consider this a major issue, however; I suspect it was a conscious design decision with good reasons behind it.
Another issue is the inconsistent difficulty. Eventually the missions can get frustratingly difficult and there doesnt appear to be a way to reduce the difficulty. Having the ability to tone down the difficulty for a more relaxed and enjoyable experience would go a long way to improve the games longevity and replayability.
If you like this type of game, check out Mass Effect Infiltrator as well as there are some similarities between these two.
