The corporate-behemoth organism that is Blizzard Entertainment, which exists in a symbiotic state next to megaton game publisher Activision, became blurrier on Friday with a surprise announcement: It has absorbed a game studio within the Activision family, effective immediately.

Vicarious Visions, a longtime game studio that was acquired by Activision in 2005, has been shuffled out of the Activision ecosystem and pumped directly into Blizzard's veins. In a statement offered to GamesIndustry.biz , Blizzard confirmed that the 200+ staff at Vicarious Vision has been shifted to a "long-term support" team focused entirely on "existing Blizzard games and initiatives." The news also includes a mild shuffle of leadership, sending current Vicarious studio head Jen Oneal to the Blizzard leadership board as executive vice president of development.

The statement did not clarify exactly when this arrangement began, nor which of Blizzard's "existing" projects would receive Vicarious staff support in particular. (Blizzard representatives did not immediately respond to Ars Technica's questions about the deal.) As of press time, neither Blizzard nor Vicarious have published details or terms about the deal on their respective blogs or social media channels. In fact, Vicarious Visions' website is currently offline altogether.
