The service is out now on Xbox 360 and arrives soon on PC and PS3
While at first only YouTube was supported for live streaming output, Twitch TV has now confirmed that its own service can also be used by the game.
Twitch TV streaming is currently available in the Xbox 360 version of Black Ops 2 and should be included in the PS3 and PC editions of the game soon enough. Sadly, no mention was made about Black Ops 2 on the Wii U.
Those that want to live stream their multiplayer sessions need only to connect their Twitch TV accounts from within the game and start broadcasting.
Check out a video announcing the new feature above.
