While it's not likely to hit shelves, I'm always excited to see new developments for Laser Tag. One of the best annual events to showcase these is always TagFest Northwest, hosted by 1 Source Laser Tag. It's an event that, while I've still not been able to attend one in my years of laser tagging, I always look forward to. Many of my "heroes" of laser tag attend and have customized gear on hand to show and share. This "Shotgun Prototype" LTAR pictured to the left is likely that of TagFerret (who is responsible for LTTO, LTX, and LTAR development).
NOMAD to the Turreted LTX setup, there's a lot of neat devices and customized gear that turn heads. While not nearly as active/publicized as Nerf modifications, Laser Tag modifications certainly have their own level of complexity as far as electronics are concerned.
More news should trickle in about this event and I hope to learn more about the new gear unveiled at TagFest!
