Well would you look at that: The announcement for next week’s Rock Band DLC has arrived over 12 hours early, and it’s a biggie: Tuesday will see the release of Megadeth’s seminal Rust in Peace album in its entirety. So now you’ll get to see if all your playing of the “Hangar 18″ cover in Guitar Hero II has sufficiently prepared you for the real thing.

Megadeth	Holy Wars… The Punishment Due
Megadeth	Hangar 18
Megadeth	Take No Prisoners
Megadeth	Five Magics
Megadeth	Poison Was the Cure
Megadeth	Lucretia
Megadeth	Tornado of Souls
Megadeth	Dawn Patrol
Megadeth	Rust In Peace… Polaris

No official word on price yet, but if I had to guess I’d say the tracks will likely go for $2 apiece, and oh, let’s say $14 for the whole album? That’s what I’m going with. EDIT: Bah, I was a buck off. It’s $14.99 on PS3, 1200 Microsoft Points on 360.

The tracks should hit at the usual time next week. And if you haven’t been exposed to this prime example of early-’90s metal, the album is embedded after the break.

And by the way, in case you didn’t see it on the Plastic Axe Twitter feed, Harmonix has made that Who medley official. It’ll be called “The Who Super Bowl S-mashup,” and it’ll appear Sunday after the game for two bucks. Still no word on what songs will actually make up the medley, but I think we can come up with some pretty solid guesses.
