Fans of the magazine know that we jump on Xbox Live once a month to play a game against our loyal readers. We call it "OXM vs." and it's just a chance for us to get out there and goof off with you all. We usually lose, but that's okay with us. We just like playin'.

On Thursday, December 20, the game in question is Undertow -- one of our favorite XBLA games of the year and, as the recipient of a 9.0 score, a winner of the coveted Editors' Choice award. It's a fast-paced, 16-player shooter featuring different classes, great opportunities for teamwork, and lots of surprises. If you need a little strategy advice, check out our 3X Power-Up.

To join in, log onto Live at the specified time (generally 4pm in our neck of the woods here in California, which is 7pm on the east coast) and look for one of our editorial gamertags -- Francesca OXM, Corey OXM, Paul OXM, Dan OXM, Ryan OXM, plus Gary OXM from our art department and Intern OXM from our salt mines. Not every staffer can play every time, but we try.
