Back in March, Niantic finally added the mythical Pokémon Mew to Pokémon GO with the introduction of research quests. These come in two different forms: Field Research and Special Research, and provide you with regular rewards for completing objectives.

A Mythical Discovery was, at the time, the only Special Research quest available in Pokémon GO, and it's the quest you have to complete to get your grubby little mitts on Mew. Completing it requires you to work your way through a series of eight different objectives, which can prove pretty time-consuming.

In this guide, we're going to try and make this as easy as possible for you. We'll list all of the requirements for each stage to help you to plan ahead. Certain steps you can only perform when you unlock them, but there's many that you can prepare for ahead of time.

How To Catch Mew In Pokémon GO

To catch Mew in Pokémon GO, you have to complete the Special Research quest A Mythical Discovery. This is located in the same place as your Field Research quests. Tap on the binoculars icon, then visit the 'Special' column.

Complete all of the objectives for the Special Research Quest and you'll collect Mew at the end. Now, here's how Special Research Quests work in Pokémon GO.

Special Research Quests Explained

Special Research are story-driven quests that require you to perform eight different stages of objectives, which generally cover all aspects of the game from evolving Pokémon to battling in raids. They aren't to be confused with Field Research quests, which offer quick-fire daily quests for a little reward.

While you have to complete objectives at the point you unlock them, you can prepare for certain tasks ahead of time. Good examples of these are earning medials, reaching a certain level, or evolving certain Pokémon.

To help you prepare, we've got a list of every single objective, organised by stage, below. So go ahead and check what you have to do to beat the quest. We'll pop an asterix (*) by the quests you can work on ahead of time so you can instantly recognise them.
