In Android Assault , an alien species called the Xias have targeted human beings for extermination. They have assembled a massive fleet that has crushed any opposing ship that has been sent their way and has started to attacking colonies stationed on nearby planets with a collision course to Earth, and it is up to the player to stop them.
The gameplay is a side-scrolling shooter, similar to R-Type , where the player takes control of a space fighter that can morph into a cyborg called Bari-Arm. The player has an arsenal of weaponry, including the Thundercracker, Burning Wave, and Chase Cannon, along with picking up health and power-ups left behind by destroyed enemies.
There are several stages ranging from asteroid belts to underwater environments, each containing an enormous boss that the player must defeat to advance to the next level. There are also animated cut scenes that tell the story of Bari-Arm.
