Airsoft
Airsoft, also known as survival game in Japan where it originated, is a team-based shooting game involving participants eliminating opposing players by shooting and tagging the latter with spherical plastic projectiles shot from low-power toy airguns known as airsoft guns. Although similar to paintball in concept and gameplay, airsoft pellets do not leave visible dye markings on their target and hits are not always apparent, though the pellets can sometimes leave small bruises or welts on exposed skin (and so protective gear is still recommended).
