X-COM: Terror from the Deep (1995)
X-COM: Terror from the Deep is a strategy video game developed and published by MicroProse for the PC in 1995. Terror from the Deep is set in 2040, four decades after the events of UFO Defense. Following the destruction of the alien Brain on Cydonia, a transmitter remained active there which awakened a group of aliens under the Earth's seas who had lain dormant for millions of years. After awakening, the aliens proceed to terrorize seagoing vessels and port cities, kidnapping humans to perform bizarre genetic experiments on them. X-COM, which had been disbanded after the first alien war, is revived by the Earth's governments to fight this new menace as the aliens' ultimate goal is to reawaken their supreme leader, a being that cannot be stopped once revived.
