Pull Me Under is a song by Dream Theater. It is the band's most well known song, jokingly referred to by the band as their Greatest Hit, and is the final unlockable song in Guitar Hero World Tour. The only way to unlock the song is to beat the game, as even the cheat code to unlock all songs will not unlock it. It is fairly difficult on all instruments and does require skill. It is first played throughout the ending credits, during which the player(s) cannot fail the song and are not scored, similar to Through the Fire and Flames in Guitar Hero III: Legends of Rock.
