At the top of the Leaderboard for this current Boss Event is someone who has supposedly racked up a total of over 3 and a half MILLION points. Just imagine how many Levels you would need to clear, how many Energy Boosts you would need to buy, how many Morale Boosts as well, to achieve that score. Quite apart from that, just think of how much time it would take. And apparently there are 20 people with a total over one million!

Why do they do it? Is it really just for that one extra UR unit?

Who are these people? Do they really exist?
