The soundtrack consists of the top 20 songs voted for by Iron Maiden fans on the band's official website. The US version also contained a hidden bonus track of a new vocal version of "Wrathchild" with Bruce Dickinson. The game passes through various levels, starting in London's East End before progressing to a psychiatric hospital, hell, and other various locations, all of which are lifted from the covers of past Iron Maiden albums. While the gameplay itself consists of shooting the appearing enemies with the mouse cursor, it acts as a rail shooter, meaning that the player has no control over movement apart from occasionally choosing the route he will take through the levels. In spite of this, the user can select which tracks play in the background, although only one song can be chosen for each level, which led to critics complaining about the soundtrack's repetitiveness. The Ed Hunter Tour was the tour supporting the album and was the first tour with Bruce Dickinson on vocal duties since 1993, and with Adrian Smith on guitar since 1988.
