The Legend of Zelda: Breath of the Wild's Trial of the Sword challenge - which launched today as part of the game's Master Trials DLC pack - has been beaten already.
The 45-floor dungeon is packed with enemies that can only be defeated using gear you find inside - all of your current gear is removed when you enter.
As you might imagine, that makes it quite a tough proposition - yet YouTube streamer AbdallahSmash026 has just finished it in around four hours, broadcasting his efforts online.
The prize for this Herculean effort? SPOILER ALERT! You might want to look away now if you want to find out for yourself.
Still here? Good.
It's an upgrade for the Master Sword which keeps it fully powered at all times, removing the only negative thing about the weapon.
Here's another potential spoiler, unearthed by those keen-eared chaps at Eurogamer:
Listen closely to the music when Link receives his newly-powered Master Sword and there are a couple of definite sound cues from the last previous in the series, Skyward Sword. The Wii epic - a prequel to the rest of the series - revealed the Master Sword was inhabited by a spirit, Fi, who had therefore lived in the sword throughout every game you had played thus far. With Breath of the Wild accepted by fans as the last Zelda game in the series to-date chronologically, it's confirmation Fi is still in there, looking out for Link.
