I just don't think it's overly fair to SE to say they copied SCC.. They've always had an aggro-social-stealth formula.. If you've played the past Hitman games, you'd know that..
Judging by the gameplay of Absolution, they have detection arcs, cover system, and some CQC.. Right? Well - SCC was NOT the first game to have detection arcs or cover to cover.. And before SCC, Hitman has had forms of CQC moves, by using tools.. I remember caving in a guys skull with a baleen hammer oncee.. It strikes me the same as smashing an old skull into the back of a guys head..
