We all knew Mei's ice walls could be deadly as hell, but what happens when multiple Meis start placing frozen barriers one on top of the other in rapid succession?
Stacking ice walls wasn't possible in the game before, and Mitsiee believes it may have something to do with one of the game's November patches. It's fitting in a way since "Mei is a scientist who has taken the fight to preserve the environment into her own hands." What better way to to celebrate the hero than by continuing her search to better understand the world's climate and wonky physics?
Especially at a time when Overwatch's creative director is busy apologising for the character's latest holiday skin.
