First-person-shooters have a less than glorious history on mobile, mainly due to the restrictions of using a mobile keypad to play a genre originally designed for keyboard'n'mouse.
That hasn't put Qplaze off, though. The developer is working on a mobile version of PC shooter S.T.A.L.K.E.R: Shadow Of Chernobyl. The game will be 3D, but with stealth elements alongside the all-out shooty bits. There'll also be a bunch of mini-quests to complete.
