You play as the sheriff of a Wild West town, tasked with stopping outlaws who are robbing banks and kidnapping innocents. Using the control pad or Justifier lightgun, you must take out the bad guys without harming those in need.
The gameplay is fast-paced, with enemies popping up on screen from different areas. If you don't shoot them before they attack, they'll use weapons against you, causing you to lose energy. You can upgrade your gun, but be careful not to harm civilians while doing so.
