An Xbox 360 user by the gamertag Scar allegedly obtained a copy of Halo 3 Epsilon, the near-final build of the game, and went online with the title. Busted. According to this picture at Homicidal Insomniac, the name Scar won't be able to post his Geometry Wars high scores until a time where the universe is actually threatened by power-hungry polygons.
You can read a response allegedly from Scar here. We've contacted Major Nelson to find out if there is a planned server maintenance scheduled for January 1, 10000 AD. (Which, not to concern anyone, is January 1 7990 AR, or After the Robot Revolution.)
