Fans of Pokemon Go may be disappointed to find out the new Pokemon Meltan will only be available through a mystery box mechanic.

Players will have to catch a Pokemon in Pokemon Go and send it to Pokemon Let’s Go to obtain a chance at Meltan. Once the box is opened, it goes on a timer for the next available opening. And top open it again, you’ll need to go out and catch another Pokemon in Pokemon Go.

Friends will be able to send you Pokemon to allow you to open your own box as well.

The linking of Pokemon Go and Let’s Go is a good idea considering the likeness of the two games, but if this description of the mechanic is accurate Meltan is basically behind a 60 dollar pay-wall in Pokemon Go.
