I stumbled upon this game while browsing Gamespot and was quite surprised to find that it is developed by IO-Interactive, the developer behind the Hitman series and Kane & Lynch. Here is the link to the official site and you can download the demo there if you're interested.

I played the demo myself and found it interesting and fun. Controls needs some getting used to but it's good once you get it. There is a stealth portion, but it's a bit useless since the level design itself is pretty linear and the only way to the other side of the map is to fight them (Since this is a demo, it's too early to make any judgements. Hope the full game have better levels). The writing is witty, especially the part where the instructor makes fun of the enemy's intelligence as they've burned down the bridge leading to the village during the assault.
