The Joker as he appeared in Mortal Kombat vs DC Universe!In 2008, Mortal Kombat faced threats from the DC Universe in a crossover title that brought two unlikely worlds colliding together. Now, thanks to our friends at Warner Brothers Interactive Entertainment, members of Mortal Kombat Online have the chance to take control of the other universe once again; this time in the latest game bringing the chaos of the most famous (and dangerous) city in comics to the realm of online multi-player!

Gotham City Impostors lets players choose between order (Bats) or chaos (Jokerz) as they emulate the path of either the Batman, or the Joker! Boasting up to 1,000 levels of player advancement, upgrades, and a system designed for maximum customization, this is the ultimate chance to enter the streets of Gotham City and make an impact on Xbox 360, PlayStation 3 or PC!

Making an impact is what it's all about! We want you to come back to Earthrealm when you're done, though! Mortal Kombat Online is giving away three beta codes to kommunity kombatants -- granting members ground level access to the Xbox 360 Beta experience!

To enter the random draw for this limited beta access, all you have to do is register and post your 360 Gamertag on the forums! By doing so, you'll join our gamertag index, helping you connect with other users on MKO for more multi-player mayhem than you can throw a ninja's spear at! Post your gamertag in the index itself, or right here.

Edit: To give you more time to spend in the beta, we're bringing the winners draw up to January 28! That means you've got mere hours to post your gamertag before we draw winners! Don't waste any time, Jokerz (or Bats)!

To be eligible, you must enter before February 4. Winners will be notified via e-mail and/or on the forums. For more questions, post a comment and join the MKO kommunity! Keep up to date with competitions and more by following us @MK_Online, or like us on Facebook!
