Mystery Rocker is in Fact King Diamond

Probably not much of a surprise, but inspection of the Guitar Hero: Metallica trophies list reveals one for "Rock Out as King Diamond," meaning he's a playable character in the game.

Gene Simmons is thrilled. Lars Umlaut is readying his own C&D letter. Guitar Hero: Metallica is out March 29 in the U.S., May 5 in King Diamond's native Denmark and the rest of Europe.
