XCOM started as a sequel to a popular, but regionally distributed, game from England called Laser Squad created by Julian Gallop. Julian and his company, Mythos Games, had produced a series of revolutionary and one-of-a-kind turn based fantasy and sci-fi games. Laser Squad, Rebel Star and Lords of Chaos all had a hand in the evolutions on the way to creating the first XCOM game. Mythos’ big break happened when they partnered with MicroProse to release a game, which as of that time, didn’t even work.
