At the start of the game, Bomberman can enter any of four anchors, which are terrariums of other planets (that were probably drained by Altair). In each anchor there are four stages. The first and third stages are adventure stages which Bomberman must navigate by solving puzzles and blasting his way toward the "Goal Arrow." The second and fourth stages are boss stages. Bomberman must fight Sirius or one of Altair's subordinates in the second stage, and he must fight the world's guardian in the fourth.
