Memorize the pattern the outlaws appear at the building windows (do not consider the innocents) and then shoot at the windows where the outlaws (and not the innocents) appeared. If you fail you lose a life. If you repeat the pattern without errors (in a single level) you win a life and a bonus of 5000 pts.
Instructions:
Use the aim to shoot at the windows. Use +/- to enable disable sound. Use ESC to quit to the main menu.
