the fact of the sign saying that the weight limit is reduced tells us that we will have to create, or be in, a certain equilibrium with the game environment. it just might be a water game where we all have to float our robots ( we'll have to see how that works out). another idea going around is that it might be a lunar/moon based theme. I was thinking that the reduced weight would be required if we were being hanged from something, as if trying to simulate zero gravity. or the theme could be an underwater astronaut training facility (just throwing that out there).
