Where I think this "secret" endgame lies, is within the Autonomous period.

I believe Triple Play had an endgame where players drove to the end of the field (extra points for getting onto another robot).

I think they added this to the autonomous as to try and encourage more programmers to have some kind of moving autonomous instead of 6 robots sitting there.
Also note they usually don't have this double option to score in Auto...
