Just read on the VGL site, Marty himself was there!
I also just read that their visit to Australia is still TBA... which the same as its been for the past 4 YEARS!!!!! (well, it feels like that long...)
Yet another awesome masterpiece added to Halo. :not worthy:
On a side note adding to ODST music, I was browsing around youtube and found this. Supposedley "music" from Halo 3 ODST, however it sounds cool, I get the feeling that this video is fake.
