All round great game!
Without giving away too much for those yet to play this awesome game; out of the characters I must say that Haggard is by far the funniest out of the squad, with Sweetwater and Redford assisting with jokes.
The actual gameplay is superb, a large number of twists in the 'deep-but-easy-to-follow' story adds to a game that would have been more than good with just a basic story. The fact that you are in a squad full of army rejects on a quest to nab some mercenary gold before the main army does, give the game an essence of... sneakiness.
You can play this game as however you like; either as a stealth or a guns blazing FPS. Either one you choose doesn't really take much away from the story as the most of the time you are finding increasingly fun ways to blow your enemies away.
In all, a brilliant game that no-one who regards themselves as a FPS player/lover should miss out on
