Hitman 2: Silent Assassin

Hitman 2: Silent Assassin" is a stealth game developed by "IO Interactive" and published by "Eidos Interactive". It is the second entry in the Hitman series and the sequel to "Hitman: Codename 47" and precedes "Hitman- Contracts".
MS Windows, XBox and PlayStation 2 versions were released in 2002, and a GameCube version came out in 2003.

In the game, players assume the role of an assassin known as Agent 47, or Mr. 47. The game advances as players carry out contract killings by solving puzzles to arrange for stealthy, untraceable assassinations.

Hitman 2 features mission-based gameplay. On each level, the main character, 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 traps, like poisoning a drink, to terminate the target in silence. Some missions have assassination possibilities unique to the level.

47 can find disguises or remove them from an incapacitated person to blend in with his surroundings and access restricted areas. This plays in with the "suspicion" system; a bar beside the health meter on the HUD represents how much suspicion 47 garners. There are multiple ways to blend in more effectively; for example, the player can make sure to carry an AK-47 assault rifle while disguised as a Russian soldier.

Despite the usage of a uniform, being nearer to fellow guards will simply increase the suspicion as they would have an opportunity to more closely examine 47. Also, running, climbing and being in restricted places are other ways to garner concern.
47's cover can be blown if suspicion gets too high, and the disguise will no longer be of any use. It is possible to switch between multiple disguises throughout the level.

Chloroform for quietly taking down enemies and a Crossbow that silently kills opponents are available. And dual-pistol-wielding (Akimbo style) is also possible.
