Released on October 25, 1991 in Japan for 8700 Yen.
E.D.F. Earth Defense Force was originally released in the arcades in 1991. However, a lot of enemies and elements didn't make it to the Super Famicom port. Several enemies were removed or redesigned, such as the large fighters from the first stage. or the large ship that preceded the boss of the second stage, which was completely removed. However, the port features a lot of exclusive content (hence the 'Super' prefix) - it includes entirely new and unique levels and an exclusive final boss was added at the end of the game. Finally, the original arcade game had four weapons to choose from whereas the Super Famicom version features eight, but the two player option was omitted.
