Galaxy Force (video game)

￼Galaxy Force (Japanese: ギャラクシーフォース Hepburn: Gyarakushi fosu) is a Space Invaders clone developed by Sun Electronics Corporation and distributed by Gifu TOKKI in 1979.

History
It seems like Sun Electronics developed two arcade games for Gifu TOKKI, G.T. Block Perfect and G.T. Block Challenger, in 1979. After that they saw the success of TAITO's Space Invaders and wanted to start making their own games.

The first one was Galaxy Force, a clone of TAITO's popular Space Invaders.
