The action is viewed from above. Players move through scrolling battlefields, destroy enemy formations, rescue prisoners, collect weapons, and reach the end of each stage.

The available arsenal includes regular firearms, heavier weapons, and limited special attacks. Enemies arrive from multiple directions, while vehicles, environmental hazards, and bosses interrupt the advance. The arcade-style structure rewards aggressive movement and memorizing dangerous encounters.

Keep moving while firing, especially when enemies surround the player from several directions. Clear threats near the edges of the screen before advancing so that incoming fire has fewer angles.

Save powerful weapons and special attacks for dense formations, armored targets, and boss encounters. In cooperative play, divide firing directions and avoid standing in the same lane, since both players need room to retreat.
