What is "q-zar"

Q-ZAR (called Quasar in the UK, Ireland, and called LaserGame in Sweden) is a type of laser tag that was developed by Geoff Haselhurst and Omnitronics in Perth, Western Australia. The rights were later sold to Leisureplex Ltd, a company based in Ireland which in turn sold them to Q-ZAR International based in Dallas, Texas.
