The Last Chance

When the Pandora Box is opened, the player becomes trapped in a dark dimension filled with evil monsters. To survive, the player must fight these creatures, retrieve the Ancient Sword hidden by them, and reseal the box. Time is running out—if they fail, the world will be destroyed by an eternal curse. "Fight, or be consumed by the darkness forever."
