I've heard about it & there is one here in town. Its a building or dark large room with areas to hide behind. You wear a vest that buzzs or vibrates when an apponet aims & shoots at you. You have a similar gun with a helmit i believe. Once all hooked up your released in the room or rooms that are dark, its kinda like play Army but no one gets hurt. My bones are allbroken up keeping me from the fun. I am sure there is more Experienced people out there that can tell you more about it. Theu say its very fun!
