THE WORLD'S LARGEST INDOOR LAZER TAG....and we built it. This facility is located in Schiller Park, IL a few doors down from O'Hare Airport and Allstate Arena. The world class facility features 2 playing maps inside about 20,000 sq. ft. Both fields have a mezzanine level and the very latest and greatest in laser tag equipment and gaming. L3DFX served as the GC on this project handling everything from the master planning through construction.
