Hydefos

Hydefos is a single player shooter game with a science fiction theme. It was developed by Hertz and was released on December 31, 1989.

Hydefos is a shoot 'em up with smooth scrolling, a rarity on the MSX, where the scrolling is usually choppy, and a feat developer Hertz had already accomplished on a previous title, action platformer Psychic World. You pilot one of five ships through levels featuring branching paths, so two play-throughs could be different depending on where you go.
