The 21st Annual KROQ Almost Acoustic Christmas, an event hosted at the Gibson Amphitheatre in Los Angeles, CA features music from a number of popular bands such as The Smashing Pumpkins, Social Distortion, and My Chemical Romance among others. It will run for two nights, Saturday, December 11th and Sunday, December 12th. As confirmed by Rigo Cortes via Twitter, a playable build of Mortal Kombat will be available to the attendees.

Unfortunately, it appears that both nights are currently sold out. Furthermore, we have yet to determine whether this build will be the same as the one featured at previous events such as the two day Brazil Game Show on November 20th and 21st or if it will feature new, previously unseen content.

We will update the story as it develops.

Mortal Kombat is expected to be released Spring 2011 for the Playstation 3 and Xbox 360. The game marks a return to the series 2D roots and features fan favorites like Scorpion, Sub-Zero, Cyrax, Johnny Cage, and many others.
