Mercenary Ops (Unreal Engine)
I don't know anything about this game or if it has been mentioned here before but it looks kinda interesting. Description from their Facebook page - Mercenary Ops is the IOS version of the MMOTPS shooting game M.A.R.S developed by YingPei Games, formerly known as Epic Games China. SlideToPlay are saying that the game is due out next week.
