Enlarge / Spellbreak battles are full of splashy elemental explosions and floaty acrobatic dodges. Blizzard Entertainment has acquired Boston-based Proletariat, the studio behind the magic-heavy battle royale game Spellbreak. Spellbreak will shut down by early 2023 as the workers at the 100-person studio transition to work on World of Warcraft and its upcoming "Dragonflight" expansion. VentureBeat reports that Proletariat and Blizzard have been in acquisition talks since last December and that the companies have been working together since last month.
