UFO: Aftershock (2005)

UFO: Aftershock is the second in a three-game squad-based tactical strategy-RPG series clearly inspired by the original X-COM games, with similar themes and gameplay, but with its own post-apocalyptic horror spin on the concept. The game is rendered in isometric 3D and, unlike its turn-based predecessor, features tactical combat in real-time with pause. It is the year 2054. Fifty years after the disaster. Fifty years after the surface of Earth became uninhabitable. Retreating to the flying haven of the Laputa the remnants of humankind clung onto existence. Then a revolt against the increasingly rigid and corrupt human leadership of the Laputa escalated into a conflict that destroyed the colony. Now, the remaining survivors flee once again. Can they reclaim the Earth from the unknown forces that chased them into the skies?
