Skrillex has a longstanding deal w/ Atlantic leftover from his earlier band From First to Last. His label OWSLA is an imprint on Big Beat, which itself is a subsidiary of Atlantic. The cost of this was probably shared between Big Beat / OWSLA, Atlantic, and the artist himself (or his management team Blood Company). These sorts of deals get pretty convoluted when major labels are involved.

Either way, a very cool interactive experience. The only criticism I have is that they completely ignored mobile/tablet/non-Flash -- it's a Flash-based game, but if you visit the site on a non-Flash device you don't even get an alternate "Sorry, your device is not supported" message.
