Thought you knew laser tag? A Singapore-based startup is taking laser tag into the 21st century using artificial intelligence, 3D printing and drones. Tag Team Inc has spent the last six years coming up with its own laser tag technologies to upgrade the existing game, which involves teams of players armed with guns that fire infrared beams. The players wear targets that are sensitive to infrared and have to run around within an arena earning points by shooting other players while avoiding being hit themselves. To expand beyond the basic concept of laser tag, which has essentially stayed the same since it was invented in 1979, Tag Team Inc has added several different features to its games.
