In that game, you are a cowboy, with a colt and you have to kill the bad guys. For that purpose, you have to target the badies who appear at windows, in the street or on the roofs, by pointing with the mouse on them, and clicking to shoot. But take care! Don't shoot at the innocent who sporadically appear also... You have a limited number of bullets and only 3 lives. At the begining, you can choose to practice by clicking on "practice mode". If you want to play, click "Play game". The first part is in town. If you go further in the game, you will discover other places. Have fun!
