Top quality game, although the storyline was lacking, great take on the stealth genre to provide a fresh change from some of the Splinter Cell games, and to let you live as a contract killer. Great difficulty levels to challenge first time gamers and veterans, as well as great weapon customisation.
Superb game, great satisfaction in seeing the credits rolls through at the end, even though the storyline wasn't great, the gameplay was so excellent, I spend hours simply stuffing around with the gravity gun. Game starts out great and only gets better, if you have it and have stopped without completing it; I urge you to complete it.
