A mysterious alien race has seized the colony of Delia IV, the solitary Terran planet among a maze of floating rocks and ice in the outer frontier arm of the Andromeda Galaxy. You are Riki Sanada, a genetically enhanced pilot with reactions 33 times faster than ordinary humans. You exists solely to fly the Phalanx A-144, a prototype strike fighter equipped with the most advanced weapons ever created. The Andromeda arm is teeming with an armada of powerful alien spacecraft. You're the only Terran pilot for thousands of light years ... that should make the odds just about even.

Phalanx is a space shooter with 8 side-scrolling stages. Features 4 primary special weapons that can be upgraded and 3 missile types.
