In this game, there is a radio controlled K9 shock collar. Specifically, this one: http://www.amazon.com/gp/product/B00LVUOYSW/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
This collar is very vulnerable to replay attacks as well as easy demodulation for custom replay via gnuradio companion.
The collar responds to signals in one of four ways:
- A beep
- A vibration with intensity between 0 to 100
- A light
- A shock with intensity between 0 to 100
The game master will transmit a series of these signals at 433.825 MHz, and you the players will receive these transmissions. It is up to you to figure out what each transmission is, and if you are so bold, you will wear the collar (not around the neck) and transmit your signal. A null response from the collar is not a successful transmission; it must present one of the four aforementioned responses.
Are you game?
