ArmA II

Building on 10 years of constant engine development, ARMA II boasts the most realistic combat environment in the world. It models real world ballistics & round deflection, materials penetration, features a realtime day/night cycle and dynamic wind, weather and environmental effects. The simulation of a combat environment is so effective, the engine forms the basis for training simulators used by real armies the world over. Although ARMA II is set in the fictional ex-soviet state of 'Chernarus' the gameworld is actually a 225 square kilometer chunk of the real world! ARMA II's highly detailed landscape is a meticulous facsimile of real terrain, modeled using extensive geographical data.
