Smoking Gun is a single-player, western-themed, vertical scroller shoot 'em up arcade game that serves as a spiritual successor to a classic 1990s arcade game. It challenges players' reflexes and accuracy with a fresh story and a modern game engine. Set in the Wild West, the game follows the Arizona Ranger as he rides into Hickstown to confront the notorious Red Rock Raiders gang, who are seeking vengeance after the mysterious disappearances of their members. The Ranger, armed with his trusty big iron, must navigate the dangers of Red Rock Valley to assist the Sheriff and his deputies.
