So this one is probably an iOS game.

Square Enix Europe has trademarked something called Hitman Sniper Challenge, a filing discovered by Siliconera has shown. This is the second such trademark registration in weeks following the discovery of Hitman Profession, leading speculation that particular name was linked to the Hitman title being made as Square Enix Montreals debut title.
Square also has IOs Hitman Absolution, set to launch later this year for PS3, 360 and PC.
