Controls: Move Cross hair - Mouse Shoot - Left Click Reload - Space Bar Score for hits on bandits. Also watch out for bottles and dynamite. Game is over when lives run out or you get hit by dynamite. Hit a TNT barrel to take out all enemies on screen. Select Easy, Medium, Hard or One Hit difficulty to determine how many lives you start with.
Changes from Stand off include addition of a shotgun, another difficulty level of one hit and TNT barrels which take out all enemies on screen. Would appreciate feedback for any glitches found.
