How Pokemon: Let’s Go, Pikachu / Eevee handles finding Shiny Pokemon

Something that Pokemon: Let’s Go, Pikachu / Eevee touched on at E3 is the handling of Shiny Pokemon. With members of the press having access during the NintendoVSUK this past weekend, we have clarity on this element of the game.

Shiny Pokemon will have the same exact appearance as other Pokemon in the overworld, though there is one exception. These creatures have a small glimmer – or an aura. Players can look for small star-like particles above the Pokemon, which indicates that it’s a Shiny Pokemon. Simply touch the Pokemon and catch it before it disappears from the map in order to add it to your collection.
