Three rounds of fun in Halo 3 for 3 sweepstakes

We've stumbled upon another giveaway and wanted to share it with you so you could (possibly) win free swag and this little gem of a contest features Halo 3 prizes galore. This Xbox Newsletter sponsored Halo 3 for 3 sweepstakes started today and runs through October 25th in three separate "rounds". Each round runs for a few weeks and can only be entered during the period in which it is open, but each week the prize offerings get better and better. How good? Well, by the third round the grand prize will feature a Halo 3 Xbox 360, Halo 3 Zune, Halo 3 Legendary Edition, Halo 3 accessories, a Halo Graphic Novel autographed by Bungie, and a Halo 3 themed guitar. Are you seeing a reoccurring Halo 3 theme here? Be sure to enter round one today and keep an eye on the page in the weeks to come to enter future rounds. Oh yeah, this contest is only open to US residents, so good luck Halo fanboys!
