Battle Unit Zeoth

"Battle Unit Zeoth" is a futuristic 2D side-scrolling shooter. You control Zeoth, who can move to the right and shoot at enemies. The odd-numbered levels are horizontally scrolling levels, while the even-numbered levels are simple "platform" levels. Each level ends with a boss battle. Zeoth can fly using a jetpack (though the player must tap a button to resist gravity) and shoot in four directions (right, left, down, and up). The basic weapons can be upgraded. The mech can take some damage before being destroyed and has only one life—but there are unlimited continues.
