Niantic announced a big update to its hit game Pokémon Go. Later this week, more than 80 Pokémon from the Johto compendium will appear in the game. That’s not all the generation two Pokémon, but it is nonetheless a substantial update to a game that has seen bug fixes and refinements, but limited new content since it debuted last summer.

In addition to adding a subset of Pokémon from the franchise’s Gold and Silver games, Niantic is adding new game elements including two new collectable berries, new Pokémon trainer outfits, and evolution items. Other items will be available for purchase from the in-game Pokémon Go shop.

Pokémon Go became an instant phenomenon in many parts of the world when it launched last year, but its popularity has waned substantially. It will be interesting to see if the new content released this week will reignite interest in the game.
