Airsoft

This character plays airsoft

A team game in which participants eliminate opposing players by tagging them out of play with spherical plastic projectiles shot with mock air weapons(usually powered by an electronic motor).

Although similar to paintball in concept and gameplay, airsoft pellets do not leave visible markings on their target and hits are not always apparent. Though the pellets leave bruises or welts on exposed skin (and so protective gear is recommended), the game relies heavily on an honor system in which players who have been hit are expected to call themselves out.
