You plunk down $6.50 for 20 minutes, then hang a brightly colored pad that resembles a flotation device around your chest and shoulders. Laser gun in hand, you step into a maze, try to get your bearings, and start firing at other players -- up to 30 at a time per session -- who also have you in their sights. Loud music (oddly enough, we heard classical piano blaring over the speakers one day instead of the usual thrashy stuff) helps the disorienting effect.
There are numerous nooks and crannies in which to hide -- or, if you're the aggressive type, from which to spring. It all ends in a flash, and a computer printout tells you how many humans you've shot, and how many have shot you. What a blast.
