When Nintendo confirmed therumors ofTwilight Princess HD, it also teased thatthe game would feature brand new content not seen in the original 2006 release. While Nintendo has yet to make any official announcements, it looks like Amazon France has let the cat out of the bag, revealing all the new content that will be available inThe Legend of Zelda: Twilight Princess HD.

It appears as though the biggest piece of new content slated forThe Legend of Zelda: Twilight Princess HDis a brand new dungeon that Nintendo has developed for the game called The Twilight Cave. The bad news is that the only way to unlock the dungeon seems to be by using theWolf Link amiibo, which is sure to be difficult to find come launch.

Hopefully Nintendo makes it possible to unlock the dungeon in-game through other means, or allows Wii U owners to purchase it as DLC from the eShop. Unfortunately, both scenarios seem unlikely, and it is probable that users will be forced to purchase the Wolf Link amiibo to experience the new dungeon.

The game’s other amiibo functionality is far less substantial, however. The other Zelda amiibo, such as theToon Link and Sheik amiibo, will allow players to do things such as regenerate hearts and arrows instantly. It’s unknown which Zelda amiibo does what, but expect Nintendo to clarify within the next couple of months.

Luckily, not all of the new content found inTwilight Princess HDwill require amiibo to experience. The Amazon France leak confirms that players will be able to manage Link’s inventory using the GamePad’s touchscreen, and that Hero Mode will be included as well. For those unaware, recentZeldagames, such as theWii U version ofThe Wind Waker, have added Hero Mode as a way to give veteran players an extra challenge. In this mode, enemies require more hits to kill, and Link has less hearts. Hero Mode will be an option from the outset inTwilight Princess HD, and will not require players to unlock it.

It may disappoint some that Nintendo is locking content like new dungeons behind amiibo paywalls, but considering the sales success of the figures, it’s hard to blame them. Consumers have been buying amiibo like hotcakes, and so Nintendo has responded by increasing the importance of the figures in games. This seems like a trend that’s likely to continue moving forward, so Nintendo fans should be prepared for more games to require amiibo to unlock significant content.

The Legend of Zelda: Twilight Princess HDwill be available March 4th, exclusively for the Nintendo Wii U.
