Financials of the deal were not disclosed.
Bungie formally had an exclusive partnership with Microsoft, but the two split in 2007.
"We chose to partner with Activision on our next IP because of their global reach, multi-platform experience and marketing expertise," adds Bungie President Harold Ryan. "From working together over the past nine months on this agreement, it is clear that Activision supports our commitment to giving our fans the best possible gaming experiences."
The Halo franchise has so far brought in $1.5 billion in revenue, and Bungie has sold over 25 million units worldwide.
"Bungie is one of the premier studios in our industry and we are extremely pleased to have the opportunity to work with their talented team over the next decade," says Thomas Tippl, Chief Operating Officer of Activision Blizzard. "Bungie has developed some of the most compelling and successful games, multiplayer experiences and thriving fan communities, and this alliance underscores our long-standing commitment to foster the industry’s best creative talent. Our unprecedented partnership with Bungie will enable us to broaden our pipeline of exciting new games as we continue to strengthen our industry position and pursue long-term growth opportunities."
