This is awsome. The “Survivor Shot” revolver by Tomy is a kit for playing laser tag wherever you want. It includes a toy gun and a headband. The gun simulates as a 10 bullet revolver, and the barrel actually rotates. The headband has an optical receiver that covers 360 degrees and vibrates when it’s been hit within a range of 15 meters.
One pair of these kit will cost around $83.
