Hitman: Codename 47

released in 2000

As the enigmatic Hitman, you must use stealth and tactical problem solving to enter, execute and exit your assignment with minimum attention and maximum effectiveness. For a price, you have access to the most devious devices, but how you use them will determine if you retire as a millionaire or get permanently retired.
The Hitman is the world's most accomplished and wealthy assassin; however, he is plagued by a troubling past of deception and genetic butchery. The ingenious story will evolve over five chapters of heart-stopping action. Remember, the world of contract hits rewards a quick intellect more than a quick trigger finger.
