Activision has told Eurogamer that Guitar Hero: Metallica will be rocking onto European shelves this May.
The publisher's comments come after a internal schedule was supposedly leaked to French website LiveWii, citing the same date.
The news is also hot on the heels of US retailer GameStop claiming Guitar Hero: Metallica will be out there on 29th March.
Metallica follow Aerosmith as the focus of a spin-off Guitar Hero game, and bring with them full drum/guitar/microphone GHWT support plus fancy sounds for the GHTunes recording studio.
In celebration of the bonkers ability of band co-founder Lars Ulrich, Guitar Hero: Metallica will also sport an Expert Plus drumming difficulty and freestyle drum fill mode. There's lots of Metallica trivia, photos, set lists and videos, too.
Guitar Hero: Metallica is in development for Xbox 360 and PS3. A full track list can be found where we last wrote it.
