The Legend of Zelda: Breath of the Wild - The Master Trials

The Master Trials is DLC to Breath of the Wild, which adds new gameplay modes, features, and items. In the Trial of the Sword challenge, Link fights through around 45 successive rooms of enemies, and must finish each room before proceeding. The character begins with no armor or weapons, but is ultimately rewarded with a perpetually glowing Master Sword that does not break if they are able to complete it.
