Hitman: Codename 47

Hitman: Codename 47 takes place from a third-person perspective, but the control setup is similar to a first-person shooter... Although mission criteria may vary, the goal is generally to find 47's assigned target and kill them by any means possible... it is possible through various ways to accomplish the mission and approach a target directly without eliciting a violent reprisal. The game... emphasises stealth... giving the player a higher financial reward for doing so. (wikipedia.org)
