Those looking to get a Halo 3 Xbox 360 console for free should participate in the Goozex Facebook program. The online video game trading site has announced a Facebook member sweepstakes for the month of October, giving away the aforementioned special edition console to four lucky winners.

The promotion is open only to US and Canadian residents who are members of the popular social networking site. Members will need to download and share the new application developed by Goozex. Winners will be selected based on the number of active friends they invite and who use the application. The Goozex-developed application allows users to share their own game reviews, ratings and personal libraries with their friends and other users of the website.
