Bungie will complete the handover process for Halo on March 31, passing responsibility for the iconic shooter series to Microsoft's internal studio 343 Industries.
"All live Halo data will be managed by 343 Industries, and Bungie will no longer be able to update game stats and player service records, to host new user generated content, or to operate the Bungie Pro service," confirmed an official statement.
"All currently supported, Bungie-developed Halo titles will be impacted by this change. Bungie will preserve all existing historical Halo data on Bungie.net for as long as the Internet and Bungie's data storage systems remain functional."
Bungie has recently shown an interest in the mobile market and launched indie venture Aerospace, but has yet to reveal its next AAA project.
