Players advance through five missions in a side-scrolling format, using firearms, melee knife attacks, grenades, and rescued weapon upgrades to survive waves of soldiers, vehicles, and bosses. Vehicle-based Slugs such as tanks and other special machines add firepower and temporary protection. The game emphasizes quick reactions, enemy pattern recognition, and checkpoint-based progression after losing a life. New to this entry are branching situations, more elaborate stage events, and transformation states that change how the character behaves.

Keep moving and avoid getting trapped in narrow spaces. Use heavier weapons to clear dense enemy groups and save strong firepower for bosses. Rescue prisoners whenever possible, since they often grant useful weapons or points. Learn when to stay in a Slug vehicle and when to abandon it before it is destroyed. If you become a zombie, look for a cure quickly, because the altered controls and attack behavior can put you at a big disadvantage.
