Juno First is a kind of overhead shoot ’em up, but with a three-quarters perspective into the screen.
You move your ship along a planet surface, made up of moving dots and shoot at oncoming enemies which come at you from the horizon. It’s very simple stuff, but was an early colour arcade game from Konami and a reasonable attempt at creating something playable and different in the emerging genre.
Juno First was released into arcades in 1983 by Konami in Japan and Gottleib in North America.
