The mobile version of first-person shooter S.T.A.L.K.E.R. will boast 3D gameplay, stealth and mini-quests. The plot will be like the PC version of the same game, with known characters, heroes, objects and locations, but will not replicate it. A unique 3D engine will be used, allowing the game to work even on weak phone models. The gameplay is "maximally realistic" with detailed hit model, bullet wounds, and real type of weaponry.
