Space Harrier 3D — About this game
Harrier returns to Dragonland with his blaster, moving between incoming monsters, projectiles and obstacles. This separate adventure has thirteen stages followed by consecutive captain battles and the final enemy. Survival depends on reading the depth of approaching objects and changing position before a collision. Both action buttons fire, leaving movement and timing at the centre of play. The original presentation uses SegaScope shutter glasses; an unlockable 2D mode is available through a special high-score entry, rather than a normal title-menu option.
