The game uses a side-scrolling perspective with linear stage progression. You drive an armored vehicle through roads, city streets, and coastal terrain while firing at tanks, turrets, aircraft, and obstacles. At designated points the vehicle transforms into a submarine to traverse water and underwater segments. Progress is stage-based and failure generally sends you back to retry the current stage, so learning enemy placements, timing the transformation, and managing forward movement are key to survival.

No named characters

The game focuses on a special combat vehicle rather than on a cast of named protagonists or villains.

Take out fixed turrets and barricades early, since they can drain your health repeatedly while you advance. In narrow sections, avoid rushing straight ahead and move deliberately to reduce collision risk. When the vehicle transforms into submarine mode, slow down and prioritize safe positioning over speed. Surviving dense enemy fire is usually more important than forcing a fast push to the end of the stage.
