Microsoft was relying on EA to boost sales of its Xbox One console in the face of competition from Sony's PlayStation 4. Larry Hryb from Microsoft's Xbox team took to Twitter to reassure users there were no problems with the game itself.
"If you are having issues signing into Xbox Live, we are aware of it and actively working on the issue. This is not a Titanfall issue," he said.
Microsoft said that it was aware of the issue, a tweet on the official Xbox Support account said the issues had been fixed. Titanfall developer Jon Shiring also tweeted: "Patch is out. Things are starting to recover quickly now."
