Mercenary Force — About this game
Recruit up to four fighters and guide the entire group through a scrolling battlefield. Different members bring distinct attacks and individual life totals, so formation and leader choice affect both firepower and exposure. Fire, rearrange the group or change the lead as enemy patterns shift. Losing a member weakens the squad, making careful positioning more useful than treating the whole formation as one disposable ship.
