Call of Duty: Black Ops 2 in-game Twitch.tv broadcasting is now live on Xbox 360.
It's coming soon to PC and PlayStation 3, but Activision and Twitch failed to mention Wii U in their joint announcement this afternoon.
The new feature means you can broadcast your gameplay directly to your Twitch channel from within the game itself without the need for additional hardware or software.
Twitch said Black Ops 2 has consistently been one of the most popular games on its video streaming service since it launched in November, so the partnership makes sense.
To broadcast, connect to your Twitch account from within the game and go ahead and go. If you want to show the world your face it's webcam enabled for picture-in-picture broadcasting with Kinect. You can share your live feed to Facebook and Twitter, too, if it takes your fancy. A video tutorial is below.
At Gamescom in August Treyarch design director David Vonderhaar told Eurogamer Black Ops 2's live streaming performance issues, if there are any, will be the result of player bandwidth and not the game itself. "It doesn't have a lot of negative at all right now," he said. "This is why it has to be in League Play, because the League Play networking is set up for it.
"Look, you can't catch me saying never, because there's one thing I don't have in our control, and that's your bandwidth. If I said to you, no, it's never going to have any performance implications and then you don't have enough bandwidth to actually upstream, that wouldn't be a fair thing to say.
"But it's not having any game impact. That's a really important part, and that's measurable, and we know that.
"For an average gamer, he doesn't necessarily understand and know the difference between when the game is performing well because of the game or because of something on the networking side. It's a rough thing to square up for people. So I say, we live stream all the time. We're testing and we're evaluating the performance on the game all the time. It's not having a negative impact on the game. But we also have lots of bandwidth."
