Game

  • Wear badge during DEF CON.
  • Earn points by firing at other people you encounter wearing the badge. Score more points for tagging more unique other people each hour.
  • Periodically scan QR code on badge screen to sync to online leaderboard.

Caveats

Not as good as real laser tag because:

  • Badge has no visible laser dot to help with aim
  • IR beam is not as narrow as real laser tag (to make up for lack of visible laser dot)
  • Scores aren't synced to leaderboard in real-time--each player needs to press a button on the badge to generate a QR code and then scan it to upload their record of hits to server
  • LVCC is not as good as a real laser tag arena due to: 1) ambient light, 2) reflective surfaces. The increased ambient light makes the maximum overall shot range less (especially around sunlight), and the reflective surfaces make it so shots at short range may "hit" even if the aim is bad.

Can I tag Laser* Tag Badge with a Flipper Zero?

Kind of...you can make the Laser* Tag Badge light up and print a message, but for fairness it doesn't count for actual points. Here is the .ir file you'll need.
