Marksmen weave in and out of buildings clustered on Kapolei Airsoft's barricade- and obstacle-littered fields, an expansive urban terrain that accommodates up to two indoor and outdoor bouts at a time. Under the watchful eye of trained field officials, participants clad in face protection commence contests that simulate military scenarios, urban combat, and armed square dancing. Before firing off 6mm BBs fashioned from ABS plastic at opposing teams, players run through safety instructions at pre-game briefings. Visitors can join new rounds of combat––lasting until midnight every Friday and Saturday––during walk-on contests, via membership outings, or through one of Kapolei Airsoft's party packages.
