Just a friendly reminder: This is your last chance to enter to win one of five codes for the upcoming Defiant map pack for Halo: Reach. If you win, you will have access to this downloadable content one day before the rest of the world! (Maps hit on Tuesday, 3/15...but we hand out the codes on Monday when we get them from Microsoft.)

Here's how you enter:

1.) Follow us on Twitter.

2.) Tweet this out to your followers:

3.) Put your Twitter name and a link to your Tweet in the comments HERE (*not* below in this post) as proof. (Find that link by clicking on the Tweet's date stamp.)

NOTE: When commenting, you must be registered on Bitmob with your real, full first and last name and a valid email address or else we won't count your entry. To register, click the link in the upper-right corner of the site.

On Monday, 3/14, when we get the prizes in hand, we will draw five winners at random and send them the codes via the emails they registered with on Bitmob (make sure @bitmob.com will get through your spam filters).
