 There are six or seven levels (depending on which version of the game is being played) that are split into four subsections, each with its own end-of-level boss. Between levels the story is explained and moved forward through the use of short animated cut-scenes with text on the screen. Players can often choose their own path through the level by selecting a door or arrow using the gun. Several of the home system versions feature light gun support; however, all of them allow the player to move a crosshair to target enemies. The multiplayer game is identical to the single-player experience, but the Sega Master System, Commodore 64 and ZX Spectrum versions do not feature multiplayer.
