Splinter Cell: Conviction was one of the most heavily anticipated Xbox 360 releases this year. This game was in development by Ubisoft for over four years. The outcome of all their hard work was a great game. It offers several different ways to play the game. The single player campaign is about 10 hours of mostly stealth action, but the new Mark and Execute command let's you truly utilize a master spy's power. Mark and Execute unlocks every time you perform a hand to hand stealth takedown. Once you have a mark and execute point unlocked you can target several enemies at once, and when you have them all in your sights you will instantly shoot all targeted enemies in face. This is a very productive skill that the game leans heavily upon. The game can be found very cheap now, do yourself a favor and check it out!
