Linkin Park are reaching out to their fan base once again and if they respond to the latest call for action, the group will reveal their 'Castle of Glass' music video early. There's a catch though, as the band is directing fans to test out the multiplayer beta for the upcoming game 'Medal of Honor Warfighter' game from EA.

In the new design, best-of-the-best soldiers from around the world will battle it out in multiplayer gaming to determine who will reign supreme. When 3 million fans download the beta, the Linkin Park 'Castle of Glass' video gets unleashed. The video was a collaboration between the band and Danger Close Games, offering a unique mix of live action footage edited with gameplay recordings taken from the game itself.

Fans that download the beta from the Xbox Live Marketplace will also be awarded with 60 minutes of Double XP once the full game launches. For further info on the game, visit www.medalofhonor.com.

In other Linkin Park news, the group is also reaching out to the DJs, producers, and remixers in their fan base. The band is currently serving up the acapellas and instrumentals from their 'Living Things' album for use in making remixes. Check out the stems here.
