Pokemon Go Halloween 2023, Part 2

Article by Brian Tein

Oh boy, this is a big one!

As we say every single year, Halloween was the first major event in Pokemon Go history, and it tends to be a really important event every time it rolls back around. But oh boy, I don't think that anyone expected this year's event to go this hard. We've got new Shadows, but these aren't just any random shadows: they're game-changers to say the least! It's taken us a bit to get this post together due to just how many important pages we had to make first, but let's take a look at what Niantic has in store.

Oh, and don't worry; we'll finish the update to the site, including updating the tier lists, soon.
