Paintball is a competitive team sport where players use air-powered markers to shoot small, round capsules filled with paint at opponents. The objective is to eliminate players from the opposing team by hitting them with these paintballs, which burst on impact, marking them with paint. Games can take place in various settings, including outdoor fields and indoor arenas, often featuring obstacles and cover for strategic play. Players typically wear protective gear, such as masks and padded clothing, to prevent injury. Matches can vary in format, with different objectives like capturing a flag or eliminating all opponents. Paintball promotes teamwork, strategy, and physical fitness.
