The Iron Maiden-inspired character will be available for two weeks this month.

GLOBAL–Rovio Entertainment will pay tribute to the heavy metal band Iron Maiden with a Halloween collaboration in “Angry Birds Evolution.”

Through the collaboration, Iron Maiden’s iconic mascot Eddie will be featured as a special playable character, named Eddie the Bird, within “Angry Birds Evolution” for a two-week period. However, players who successfully recruit Eddie to their team will be able to keep him forever.

Eddie the Bird will fly into “Angry Birds Evolution” on Oct. 18.
