Best described as a live video game, laser tag is a game in which participants try to tag each other using a laser beam shot out of a hand device attached to a utility vest. Ultrazone Alhambra: The Ultimate Laser Tag Adventure bills itself as the largest laser tag facility in Los Angeles. It is a 10,000 square foot facility with a 5,000 square foot multi-level laser tag arena, three party rooms, and a video game arcade area. Ultrazone also hosts birthday parties, sports parties, school luncheons, and day camp outings. The recommended age range for the game is six years and up, particularly because of the complex nature of the maze and the eight-pound weight of the vest. Kids do love the adventure and competition. Ultrazone is a popular choice for parties; Mondays and Tuesdays are dedicated to group events and private parties only.
