Later this month, people will be able to use Facebook accounts to log in to Blizzard Entertainment computer games such as "World of Warcraft."
The move will pave the way for Blizzard game fans to use the leading social network's Live video service to broadcast play in real time, the companies said in a joint release.
California-based Blizzard, owned by video game publisher Activision, is in the process of creating a "Go Live" feature that would let players stream on-screen action to Facebook timelines, according to the companies.
Blizzard games in line for the Facebook streaming capability included freshly released "Overwatch."
The collaboration will add social features to Blizzard games while highlighting Facebook as a platform for sharing, viewing and discussing play, the companies said.
"Our collaboration on 'Overwatch' demonstrates Facebook's commitment to partnering with AAA game companies, while further empowering Blizzard gamers to connect and share the content they're most passionate about with the friends they play with around the world," said Facebook global games director Leo Olebe.
"Overwatch" is a team-based shooter game played online.
Facebook earlier this year ramped up its challenge to Twitter-owned Periscope with upgrades to the social network's live video broadcasting feature.
A new featured was added to the Live streaming feature at Facebook to let people "broadcast: to groups at the social network or in scheduled "events."
Facebook Live launched in the middle of last year and was initially limited to celebrities but recently opened to a wider audience of broadcasters.
