Angry Birds Evolution, the odd adult-aimed offshoot of the series that spawned an animated kids film, gets a little bit stranger on October 18, when a bird based on the undead mascot of venerable metal band Iron Maiden arrives in the game. Huh.

GWAR has done it. Slayer has done it. KISS went off the goddamn chain to do theirs. And now, Iron Maiden is joining in on the metal band comic trend -- or, more specifically, its longtime mascot Eddie is.

Zero points for guessing who's behind the soundtrack.
