Xbox Live, Microsoft’s online multiplayer and media service for Xbox, is currently “limited” for Xbox 360 users, according to the Xbox Live service status page. And one hacker group is taking credit on Twitter.

The current outage is affecting core services and a few select apps for gamers that use the Xbox 360, including IGN, Maxim, and MLG.TV.

We've reached out to Microsoft's Xbox Live support team and we'll update this story when we learn more, and when the service comes back online.
