Call of Duty: Advanced Warfare doesn't include the new Share Play functionality on PS4 that allows players to have a friend play through their games via an online connection, one hour at a time, regardless of whether the friend owns the games. Share Play launched on October 28 with PS4 update 2.0, and in a statement to Joystiq, Activision says its team didn't have access to the feature while developing Advanced Warfare:
"Delivering a great gaming experience for fans is our top priority. We're focused on launching Advanced Warfare and ensuring that people have a great time playing it, which our fans seem to be. Share Play is a new feature that was introduced as part of the recent PS4 firmware 2.00 update. Our engineers didn't have access to it before it launched, so we haven't had a chance to evaluate it to see how it will impact the experience across all modes of play. Of course we wouldn't include a feature in our game without having the chance to test it. Once we've fully analyzed its performance, we'll determine how to support it going forward."
