From what I read on the First website about it, it seems to be a remote-sensor. They say it can be used with universal remotes and such. First thing that comes to mind, is that you would install one of these in your garage door to be able to open it with a remote. Other possibilities could be televisions or whatever.
But a guess to what the game could be about
: Each team's human player gets a remote which can only open one door (or possibly do some other things) And they could open and close that door for whatever strategic reasons... And that's as great of a guess you're ever gonna get out of me.
