The game uses a side-scrolling perspective with constant forward movement, jumping, climbing, and shooting. Players collect weapon pickups and can store and switch between acquired guns, which adds tactical flexibility. Stages culminate in demanding boss battles, and success depends on movement control, quick target prioritization, and learning enemy patterns and hazard timing.

Learn weapon pickup locations and try to keep at least one strong all-purpose gun in storage for emergencies. Since enemy waves can arrive from multiple directions, staying mobile is often safer than standing still and firing. Before bosses, preserve health and avoid wasting your best weapon on minor enemies if a tougher fight is ahead.
