Mining Company called "BXR"

In Halo 2 there were many different button glitches that could be used to exploit bugs in the game gain an advantage. The "BXR" (pushing the B button, the X button and the right trigger) in quick succession allowed you melee while shooting. It was a notorious glitch Bungie has included it in reach in the form of a logo of a mining company in the fiction of the game. On the two variants of the logo, the first one shows colors from the Xbox 360 controller "X", "Y" and "B".
