Trainers trying to complete their Unown Pokédex collection in Pokémon GO have another chance. To celebrate the 2019 Game Developer Conference, Unown G, D, and C are appearing in the San Francisco area.

The 2019 Game Developers Conference (GDC) is one of the largest game development conventions in the world. Studios, publishers, and developers all gather together at the Moscone Convention Center in San Francisco, California to meet, network, and share information about the game making process.

Niantic is celebrating the event, releasing Unown G, Unown D, and Unown C in the same general area as the Conference until March 22 (Friday).

There’s not much time to catch them. If you’re in the area, be sure to give it a look. Otherwise, lets hope you can trade for them.
