I just finished the story of the game, after having it bought during a sale some weeks ago. I must say, what a nice game this is. The story is great, and drags you into it. The characters all have their little quirks and their conversations are quite amusing at times. The gameplay itself feels alot like Commandos in that you spend your time avoiding the view arcs of the guards. Being spotted usually means reload (if you're a perfectionist like me), but there are ways around it if you want. The learning curve is perfect and while the later missions are quite tough at times, it never becomes frustrating. Replayability is great as well, as you unlock standalone challenges (that I have yet to start with). And each level can be replayed with different character combinations, making the same level quite different due to the difference in skills of the characters. All in all, a gem of a game, and great value for money, especially if you buy it during a sale. I didn't encounter any bug at all and the game feels solid and very well made.
