Laser Challenge Pro is a "laser blaster" with high-tech features, such as a "unique 'red dot' laser targeting system," according to product information, that allows users to see where they're aiming. Players score points by shooting the sensor on opponents barrels. The gun comes in two difficulties: Beginner and Pro. The beginner difficulty widens the blast beam to make hit registration easier. Play with any number of players in either team mode, in which team A competes against team B, or single-player mode, in which all players compete against each other.
