Hitman +

Hitman is a stealth game series developed by the Danish company IO Interactive. The series is available on PC as well as several video game consoles, including the Nintendo GameCube, PlayStation 2, PlayStation 3, Xbox, and Xbox 360. The game series has since expanded into a novel, Hitman: Enemy Within written by William C. Dietz, and a Hitman film adaptation which is loosely based on the storyline of the games.
