Great game if you like story, puzzles and stealth gameplay.
Absolutely not an ideal game if you are looking for gunplay and combat.

The story is very well written and is coherent and the setting really does help in creating a narrative. But what could have made this game more fun is to reward the player for being combative rather than stealthy. This game punishes you for being combative, and it just isn't fun to not be allowed to rush and gun down your enemies. You should be able to do that especially in a first person shooter game.

Disappointed.
