At the end of March, Bungie will no longer handle player data for Halo games. The studio issued a statement today saying the transition process between it and 343 Industries, Microsoft’s new internal Halo studio, will be completed March 31. After then, all live Halo data will be managed by 343.

Bungie’s been ready to move on from Halo for some time. The company went private again in 2008 after being part of Microsoft following its acquisition in 2000. While the Halo franchise remains a Microsoft property, Bungie has entered into a 10 year deal with Activision Blizzard and formed Bungie Aerospace, an independent developer studio that has released an iOS game called Crimson: Steam Pirates.
