The game uses simple left-right movement and single-shot firing. The player must dodge enemy shots, use shields as temporary cover, and clear rows of aliens before they reach the bottom. As enemies are eliminated, the remaining invaders speed up, making each wave more dangerous. Scoring comes from destroying aliens, with pressure increasing as the formation thins out.
Start by clearing one side to control the formation and avoid creating awkward gaps. Preserve part of the shields instead of punching through all of them. Focus on the lowest aliens first when the formation drops close to the bottom line.
