Crusader Paintball safely thrills color commandos 10 and older with adrenaline-fueled paintball games set on rugged, varied terrain. Every Sunday, referees organize teams and oversee games in which paint-gun soldiers practice combat-driven abstract expressionism according to specific rules. Players may compete to take and defend a set of bunkers or fend off assassins as a VIP bodyguard. All competitors strap on protective masks and load their air-powered markers before hitting one of four wooded fields or an open speedball field. Duck behind high fences to dodge pursuers, stalk rivals along forested paths, or crouch behind wooden obstacles while silently coordinating ambushes or surprise birthday parties. Players must fill out a waiver, which a parent or guardian must sign if the player is younger than 18 years of age.
