On the peaceful planet of Tuul, evil warrior Sarlac took control using the power of the Darkstone, plunging the land into chaos. King Vlaros, Kyle Blackthorne's father, sent him to Earth just as his kingdom was falling apart. Now, twenty years later, Kyle is grown and must return to Tuul to free it from Sarlac's grasp.
Blackthorne , a platform action game for the Game Boy Advance, follows Kyle's quest to save Tuul. Played from a side-view with non-scrolling backgrounds, the game has similarities to Prince of Persia, featuring maze-like environments and exploration-based gameplay. Players control Kyle as he fights enemies using his pump-action shotgun, which can be upgraded throughout the game. Various types of bombs are also used to damage enemies, unlock doors, or destroy generators.
