About Hitman: Codename 47

Hitman: Codename 47 sets a new standard for thinker-shooters. As Hitman you must use stealth, tactics and imagination to enter, execute and exit your assignment, getting minimum attention but maximum effect! You have access to the most devious devices, but it will cost you – how you use them will determine if you retire as a millionaire, or get retired! Hitman is no ordinary hired killer – he’s a versatile forensic artist using stealth, disguise, intelligence, advanced weapons, poison and raw power to accomplish his kills. But he is also haunted by a troubling past of deception and brutal genetic engineering. The intriguing story evolves over five chapters of riveting action. But the success of a contract killer depends just as much on a fast mind as a quick shot.

Hitman: Codename 47 on Wikipedia

Hitman: Codename 47 is a stealth video game developed by IO Interactive and published by Eidos Interactive exclusively for Microsoft Windows in November 2000. It is the first entry in the Hitman series. The player controls Agent 47, a genetically enhanced human clone who is rigorously trained in methods of murder. Upon escaping from his testing facility, 47 is hired by the International Contract Agency (ICA), a global contract killing organization. His missions take him to locations in Asia, Europe, and South America to assassinate wealthy and decadent criminals, at first seeming to share no connections with each other, but who are soon revealed to have all played a role in a larger conspiracy. The gameplay revolves around finding ways to stealthily reach and eliminate each target; to this end, players can make use of various tools, including disguises and suppressed weaponry. However, some levels are more action-focused and do not feature stealth as a possibility, instead playing like a traditional third-person shooter.
