Hitman 2: Silent Assassin

Description :

Hitman 2 features mission-based gameplay. On each level, the main character, known only as 47, is given a set of objectives to complete. Most levels require the assassination of one or more people. However, how missions are completed is up to the player, and there are almost always a variety of ways to complete missions. Instead of simply running and gunning through the mission, one can set sneaky traps, like poisoning a drink, to terminate the target in silence. Once again, it's up to the player to decide how he or she will kill the target.
