Will we ever see a proper chess-like revamp of this legendary strategy game? Probably not. So we’ll have to settle for Firaxis’ XCOM: Enemy Unknown, which almost takes its name unchanged from the critically acclaimed original (no dash!). Like the original, you assume command of a “secret paramilitary organization known as XCOM,” toiling like Mulder and Scully, only with massive governmental resources, to fend off a global alien invasion, researching alien tech to develop your own bleeding-edge weaponry and squaring off against extraterrestrials in the game’s hybrid real-time/turn-based tactical 3D battlescapes.
