Gun.Smoke is a Nintendo Entertainment System action game. Despite its name, Gun.Smoke has no relation whatsoever to the popular western series of the same name. The player controls a gunslinger as he travels through each town, killing all the bandits in his path. Power-ups can either be acquired or bought.
The game is a top-down scrolling shooter. The player can move forward, left, and right. Enemies and traps will appear at random; various power-ups will also appear randomly. Checkpoints are provided where the user can buy new weapons if he or she has acquired enough money from killing bandits.
