 The series ' next band @-@ centric title , Guitar Hero : Metallica , was released on March 29 , 2009 . Guitar Hero : Metallica is based on the full band experience of World Tour while offering similar features on Metallica 's history and music as found in Guitar Hero : Aerosmith . In addition , Metallica 's album , Death Magnetic , was available as downloadable content for Guitar Hero III simultaneously with the release of the album , with the content being forward @-@ compatible with Guitar Hero World Tour and Guitar Hero : Metallica . Since the PlayStation 2 version does not support downloading , three extra songs were included from Death Magnetic and are as follows : " Broken , Beat , and <unk> " , " Cyanide " , and " My Apocalypse " . A new feature in the game , where the drummer can access a mode called Expert + , has also been added . Expert + mode was implemented to allow faster bass pedal beats , fast to the point where it would normally be out of the playable range of a single bass pedal , and was intended for a dual bass pedal .
