X-COM: Apocalypse

Things have not gone well since the last Alien War. The world resources have been exhausted, and most of the population have been concentrated into the last hope: Mega-Primus, a self-sufficient city. Things were starting to look good until a strange portal opened in the sky, and UFOs emerged from it. It seems that the X-COM is needed again.

X-COM: Apocalypse is a sequel to X-COM: Terror from the Deep, and is the third entry in the X-COM series. It is a real-time / turn-based strategy game that features a mix of research, resource management, macro tactical combat, and micro tactical combat. At the city screen, the player controls vehicles to engage the threats (everything from rival factions to alien UFOs). If a UFO has landed or infiltration has been reported, the vehicles will land/dock at the infestation site and engage in tactical combat with the equipment at hand. Once the player managed to capture aliens and alien equipment, the scientists can research and perhaps even copy them for the player's use.
