Hitman: Absolution is tough to classify. Bad game? Nope. Is Hitman good? No, sorry. Absolution, the sequel to Blood Money, was a blunder. Cutscene-heavy, linear, and without exciting gadgets, you forget you're playing Hitman.
Silent Assassin was the first time players could poison a target's food and drink, and Agent 47's dual "Baller" pistols became his signature weaponry. Hitman's levels are large and inventive, as expected.
At their very foundation, stealth games are puzzle games. I think this explains why Hitman Go is a confident adaptation. Hitman Go emphasizes stealth's systematic approach. It's stripped-down and linear, but it still offers the Hitman high.
