Pokémon Sun and Moon players can now get access to Mega Mewtwonite X and Y stones as part of the game’s first Mega Stone giveaway by using the Mega Mewtwo code. Mewtwonite X and Y are among the strongest Pokémon available in the game, while Mega Stones, since they are untransferrable via the Pokémon Bank, are even more valuable.

“The Legendary Pokémon Mewtwo is already formidable in battle, but when it Mega Evolves into Mega Mewtwo X or Mega Mewtwo Y it becomes even more powerful. And now you can get Mewtwo's Mega Stones in your Pokémon Sun or Pokémon Moon game via a special code,” according to the official post on the Pokémon website on Friday.

Here’s how you can get your hands on Mega Mewtwonite X and Mega Mewtwonite Y using the Mega Mewtwo download code:

You will have to use a simple code as opposed to a QR code handed out in previous giveaways in the game.

Mega Mewtwo Mega Stones code: M2DESCENT

Then, you will need to follow these instructions:

  1. Select Mystery Gift on the main menu.
  2. Select Receive Gift.
  3. Select Get with Code/Password, then Yes, and then Yes again to connect to the Internet.
  4. Enter your code.
  5. Receive Mega Stones.
  6. Speak to the deliveryman in any Pokémon Center to pick up your Mega Stones.
  7. Importantly, do save your game

Mewtwo is among the rarest Pokémon in Pokémon Sun and Moon, and almost impossible to catch in the wild. However, you can catch it by accessing the Pokémon Bank, which acts like a security deposit box for your Pokémon.

Once you have caught a Mewtwo, simply follow the instructions listed above, and give it a Mega Stone to Hold.

The Pokémon company is yet to put a word on when the giveaway ends but it's better to get your hands on the Mega Stones sooner than later.
