As previously reported and now confirmed, EA Access will be free for Xbox Live Gold subscribers from June 12 until June 22.
This coincides with the company's E3 EA Play event and will allow you free access to all the games in the vault and those available for free trial.
“Want to share EA Access with a friend who couldn’t make it to EA Play? All Xbox Live Gold members can check it out for FREE from June 12-22, 2016. All they have to do is download the EA Access app on Xbox One to get started.”
Given that EA Access will be free around the same time EA Play starts on June 12, it could be that there will be a big announcement relating to the service.
Maybe we're getting all previously released Xbox 360 EA titles such as the Mass Effect trilogy for free. That's just our guess though.
