The ECS also offered four player game-play with the optional addition of two extra hand controllers. Four player games were in development when Mattel Electronics closed in 1984. "World Cup Soccer" was later completed and released in 1985 by Dextel in Europe and then INTV Corporation in North America. The documentation does not mention it but when the ECS Computer Adapter is used, "World Cup Soccer" can be played with one to four players, or two players cooperatively against the computer.
