The headline says it all and really there's not much to add. Watching the video will show some new shots of Medal of Honor Warfighter scattered here and there, but other than that don't expect to learn why Linkin Park got into EA's other next modern war shooter. It seems Linkin Park has a tune that will somehow put the emotions of the main character to music and thus make it easier for us to feel for what he's going through. That way, when you singlehandedly take down a building full of bad guys, you'll feel justified in having done so.
The game developers work hard to give you the ability to take down bad guys in cool and creative ways. If it takes Linkin Park to make it all worthwhile then so be it.
