The Battlefield 4 Community Test Environment is what has effectively let DICE get proper simulations of what full fledged releases of Battlefield 4 products- such as expansion packs- will be like before they actually release, something that is sorely needed after the disastrous launch that Battlefield 4 had last year (it was only this year that the game finally got to a functional stable point).
Now this service will be coming to consoles as well, which should mean that console players get the same kind of input in the development process of Battlefield 4 that PC players do. Of course, to have that privilege, you will need to be a member of Battlefield Premium, which costs $50 a year, so… yeah.
Battlefield 4 launched last year on Xbox 360, Xbox One, PS3, PS4, and PC. A follow up, developed by Visceral and DICE, and, controversially enough, focusing on cops and robbers, called Battlefield Hardline is due out next year.
