Penned exclusively for "Guitar Hero: Warriors Of Rock" which hits stores yesterday, Dave Mustaine has outdone himself with a new track called "Sudden Death". While the brand new Guitar Hero features a story-based adventure mode for the first time in the games' career (voiced by Kiss' Gene Simmons no less), players will have to master Megadeth's "Sudden Death" to win the game. You can now own the MP3 by visiting iTunes or listen to it streaming in the player here.
