Pokémon Sun and Moon - Mega Latios, Latias, Ampharos, and Altaria download codes for Latiosite, Latiosite, Ampharosite and Altarianite

Following on from their initial distribution to players who took part in an earlier online tournament, the Latiosite, Latiasite, Ampharosite and Altarianite Mega Stones for Mega Latios, Mega Latias, Mega Ampharos and Mega Altaria are now available via download code distrubution.

That means four new Mega Stones added to the pile of Mega Evolutions available in Pokémon Sun and Moon, and you can read on for how to download the Mega Stones and what the download codes are for Latiosite, Latiasite, Ampharosite and Altarianite, below.

Do Pokémon Sun and Moon finally prove a weird fan theory?

Mega Latios, Mega Ampharos, Mega Altaria, and Mega Latias download codes for Pokémon Sun and Moon

Rather than using a QR code, like has been done before with giveaways like that of the mythical Pokémon Magearna, the distrubution event for Latiosite, Latiasite, Altarianite, and Ampharosite works like the one for Marshadow, with it being tackled via a download code for a Mystery Gift.

Mega Latios, Mega Latias, Mega Altaria, Mega Ampharos Mega Stones code:

• DRACHE

Here's how, exactly, to download the Mega Stones in question via Mystery Gift:

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. Watch as you receive Mega Stones.
6. Speak to the deliveryman in any Pokémon Center to pick up your Mega Stones.
7. Be sure to save your game!

When does the Latiosite, Latiasite, Altarianite, and Ampharosite Mega Stone giveaway end?

We finally have an end date for the giveaways now, and it's a little closer than we thought. All of the Mega Stone codes will stop working at 23.59 UTC on October 31st, 2017.

While the codes are live, we suggest you download the Mega Stones as soon as possible - because the Mega Evolutions for Latios, Latias, Altaria and Ampharos are definitely worth having access to anyway.

It's also worth noting that you could have had your hands on the periodically-released Mega Stones slightly earlier, if you took part in specific online competitions when they were announced.

In this case, Altarianite, Ampharosite, Latiosite, and Latiasite were first made available to players back in August, if you took part in the Weakness Cup Battle competition during July.

This is essentially the format for all of the Mega Stones: entrants into specific tournaments like the Kanto X Alola Regional Rumble Competition, or the monthly Championships, will receive downloads for the stones soon after, and those Mega Stones will then be made available to all players via download code about a month later.
