Gun features a free-roaming environment, including side-missions that add to the story of the game. Gun is played by controlling Colton from a third person perspective, playing much like a traditional third-person shooter. Players can wield a revolver and switch between rifles, shotguns, various handheld explosives, and bows.

Throwing knives are available in Gun Showdown. Attacking and killing enemies fills up a "Quickdraw" gauge, which when activated slows down time, switches to a first-person perspective, and gives the player unlimited ammunition for a short duration, allowing the player to take on a significant number of enemies.

Gun is full of action n adventures ....Gun sets you loose in the Wild West, where you can shoot your way through a very brief but entertaining storyline and undertake some decent side missions while you're at it.

The mechanics of gameplay certainly are good, and even though there are only a few main story missions, they tend to be diverse and packed with intense action. Gun carefully walks the line between being a run-and-gun shoot-'em-up and more of a realistic, tactical shooter.
you'll also get to take on ferocious Apache warriors, play with barrels of TNT, fire cannons, and more.
