As promised, Nintendo on Thursday officially rolled out the first wave of downloadable content for Zelda: Breath of the Wild. You can pick it up for $20, which also includes another DLC pack scheduled to hit later this year.

The first DLC pack is known as The Master Trials and includes several new modes, items, and a new travel medallion that allows players to fast travel to points around the map. Nintendo has already confirmed that the new Master Mode will use its own save slots, which means your existing progress will be safe and sound.

In Master Mode, Nintendo says enemies will be more difficult to defeat. Not only will their health gradually regenerate, but each enemy will be powered up by one level. That means the weak Red Bokoblins in Normal mode are now Blue Bokoblins. And if you thought the game’s Lynel were hard, wait until you face them in Master Mode.

The DLC also introduces Trial of the Sword, a mode that pits Link against waves of enemies until all of them are defeated. Hero’s Path Mode, meanwhile, provides players with a map of where they’ve been in the last 200 hours of gameplay.

Additionally, players will have eight new armors to find, including Tingle’s Outfit, Phantom Armor, and Majora’s Mask. Nintendo is also making it easier to find the 900 Koroks hiding in Hyrule. Just find the Korok Mask and the Joy-Con controllers will vibrate when a player is near a Korok.

Remember, this is the first of two DLC packs coming to Zelda: Breath of the Wild. The other pack, dubbed The Champions’ Ballad, is set to launch later this year and will introduce an expansion to the main story.

In order to download the new content, Nintendo says players will need about 456MB of free space on the Nintendo Switch or 3.7GB of free space on the Wii U.
