July 14, 2520 AD. The light emitted by a "stone-like object" excavated from the strata of B.C. enveloped the earth, destroying the human race. Only the four crew members of the space cruiser TETRA and one robonoid barely escaped into satellite orbit. ...... One year later. The TETRA is forced to re-enter the atmosphere because the ship's supplies have finally been depleted. The battle for the survival of the TETRA begins.
The battlefield is a stage with various terrains, including intricate crevices and moving containers, where enemies attack from all directions, up, down, left, and right. Twenty-three bosses await in six highly strategic stages. There are also secret bonuses that occur when enemies are defeated in a specific order, as well as hidden score items. The key to obtaining a score is to cover all of these items, build your own original attack pattern, and accurately destroy the targeted enemies. Use weapons that level up in accordance with your score to update your high score!
