Hitman is the game that is about social stealth. its a game about Agent 47 a contract killer working for ICA and his mission is to eliminate his targets who are mostly criminals and gangsters.
this hitman game is back to its roots that were lost by last game absolution which turn into linear action game. and its structure is more like blood money.
here in this game you have 6 insanely large sandbox type mission, you can complete a mission whatever you want, kill target anyway you want. theres multiple opportunities. you can shoot with silencer pistol, you can kill target and make it looks like accident. the game is challenging if you turn off opportunities, the disguise system is really amazing here which suck in absolution.
the level design in this game is amazing. like best in series as you can explore the entire building and outside of enviroment.
so all in all. Hitman is probably best stealth game i have played in last 10 years. last great stealth game i played that was this good was Splinter Cell Chaos Theory and Hitman Blood Money.
Its easily one of the best game this generation produce.
