If you can find the Nike interactive advert on the 360 dashboard you can play a mini game from within it called Sonic X Vapor. All you can basically do is run and press "a" to jump, then "a" again to double jump... not that interesting however pretty random. Video below, gets repetitive: [video=youtube;LV14taUVPpg]https://www.youtube.com/watch?v=LV14taUVPpg[/video]
Dammit why don't they put this mini-game out on Xbox LIVE Marketplace up for download than just play from an advertisement, it's really annoying to remember that someday this will be removed from Xbox for some other advertisement. And it is pretty cool to play even though all you do is just jump around. By the way, no Gamer Picture is unlocked.
Pretty cool for an advert, it will be one of those random Sonic things people look back on in years to come.
