Take the role of Sam Fisher, a NSA secret agent in this sneak-em-up game. Like in the game Thief you have a light meter that show how visible you are and a set of tools the help you stay hidden. For example night vision and a silenced assault rifle. The story is about another bomb, another mad man and another Tom Clancy style USA save the world story so nothing really new. The bad part about the game is that it is very simple and linear so unlike thief there is no need to explore or to find new and fun way to do things. Walk the line and kill them when they sleep.
