Microsoft’s Xbox Game Studios is teaming up with Tencent’s TiMi Studios, developer of the wildly successful mobile hits Call of Duty: Mobile and Honor of Kings. According to a Google Translated version of the announcement from TiMi, the two companies have formed a “strategic partnership” to create “game content,” but it’s unclear exactly what that might mean or when we might be able to play anything resulting from the cooperation.

TiMi Studios is no stranger to adapting hit franchises to mobile: Call of Duty: Mobile just crossed 500 million downloads worldwide and the studio is also the developer of the upcoming mobile strategy game Pokémon Unite. Perhaps Microsoft wants to bring some of its biggest titles to mobile platforms in some way. (Not counting streaming games over xCloud, of course.)

TiMi Studios may very well be the world’s largest developer, having reportedly earned $10 billion in revenue in 2020. Its biggest title, the China-only Honor of Kings, had an eye-popping 100 million daily active users as of November, according to Tencent.
