Pokemon Go is kicking off a new steel-type Pokemon event later this week. The "Test Your Mettle" event begins Sept. 16 and introduces a handful of new steel types to the mobile game, including Mega Aggron and Togedemaru. On top of that, two new Ultra Beasts will be invading raids, and there will be new Research tasks to complete and other bonuses.
