Pokemon GO's seasonal Halloween event is set to begin on October 17th at 9pm BST (1pm PDT).

Fans will be pleased to hear that more Ghost and Dark-type Pokemon will be temporarily available both in the wild and in raids. Some of these guys include Murkrow and Gastly. And, making its grand Halloween debut, is the Spirit Pokemon Yamask.

As usual, Team Go Rocket has been up to no good. The task of saving a bunch more Pokemon falls to you, some of which include Weedle, Kakuna, Beedrill, Electabuzz, Magmar, and Duskull.

On top of that, the Pitch-Black Pokemon Darkrai will appear in five-star raids. There are also 'frightful and fun' limited-time Field Research tasks to take on. And, to add to the general spookiness, you'll receive an odd message that tells you to check out your Special Research. In doing so, you might get the chance to face a Forbidden Pokemon.

Some of the event bonuses you can take advantage of include 2x Catch Candy, 2x Hatch Candy, and 2x Transfer Candy.

For me, though, I'd have to say this update's biggest draw are the new Halloween-themed costumes that you'll be able to collect. In raids, you'll find Charmander wearing a Cubone costume, Bulbasaur wearing a Shedinja costume, and Squirtle wearing a Yamask costume. In the wild, there's a good chance you'll stumble upon Pikachu wearing a Mimikyu costume. And, if you're super lucky, you might just spot a Shiny variant of the costumed Pokemon.

The Halloween event will run to November 1st at 9pm BST or 1pm PDT. If you're one of the five people yet to give it a shot, you'll find Pokemon GO available for download now from both the App Store and Google Play. And, for the curious, here are the full event notes.
