Microsoft’s lineup of first party studios is an impressive one, to say the very least, not only because of how large it is, but also given the pedigree of so many developers that fall under the first party Xbox Game Studios wing. At the same time, however, Microsoft is also working on upcoming exclusives with external, third party partners that will be published under the Xbox Game Studios banner. In fact, currently, the company has over a dozen games in the works with external partners. That’s according to Microsoft’s Director of Live Game Operations at Xbox Game Studios, Crystin Cox, who confirmed the same in a recent video uploaded by the company (via Wccftech).
