Several FIFA players have been receiving invites to take part in a closed beta test for FIFA 15 Ultimate Team. In addition, according to EA's support site, a demo for FIFA 15 will be available soon.
Although EA has yet to announce the closed beta, the invite suggests that it will start on the 21st of August, and only a few "randomly chosen" Origin members on Xbox 360 and Xbox One will be selected. The beta will allow players to experience several features of the game, including Ultimate Team, Career Mode, Online Season, and Clubs.
"If you are selected to play the FIFA 15 Closed Beta access, you will receive an email at the address associated with your Origin Account with your Closed Beta access code on Xbox One or Xbox 360," said EA. "Beta participants are randomly chosen and contacted by email invite only."
"Don't worry, the FIFA 15 demo drops soon! Be sure to stay tuned on EASports.com, Twitter, and Facebook."
FIFA 15 will launch on the 23rd of September in North America, and on the 26th of September in Europe. More details about the game are expected to be revealed during EA's conference at Gamescom.
