After teasing two waves of additional content for those who purchased the $20 Expansion Pass for The Legend of Zelda: Breath of the Wild, Nintendo has revealed exactly what buyers will get this summer in the first wave of add-ons. A new "cave of trials"-type challenge, new armor, new tools, a new hard mode that boosts enemy strength, and a new option to track Link's progress on the map. Zelda.com lists everything in great detail. Here's the bit about the Trial of the Sword challenge:
When you get to a certain sacred location, you can take on the new "Trial of the Sword" challenge. Face an onslaught of enemies, one wave after another. Link starts the challenge without any equipment or weapons. When all the enemies in a room are defeated, Link proceeds to the next. Clear all the trials (about 45 rooms in total), and the true power of the Master Sword will be awakened, and it will always be in its glowing powered-up state while usable.
That sounds like a worthwhile upgrade to me, although you just know that the final room of the trial will be filled with silver Lynels or something else frustrating. Perhaps Guardians that fire on you while you fight silver Lynels. Better bring some extra fruit and mushroom skewers just to be safe. The new armor invokes past Zelda adventures such as Twilight Princess (Midna's helmet), Majora's Mask (the actual Majora's mask which could have some, um, interesting side effects), and even a Tingle outfit if you're into that sort of thing. I expect to be finished with Breath by the time this expansion releases (if I can ever finish the Yiga clan's hideout section), so it'll be a great excuse to revisit the game and pick up the new additions. The second wave of DLC (including the new story content) is slated for release toward the end of the year.
