If you were planning on spending the weekend playing Evolve on PlayStation 4 during the game's alpha test, then we've got some bad news, as Turtle Rock and 2K have confirmed that the game's alpha has been delayed on that platform.
In a post on their website, it was confirmed that issues with the latest firmware update on PS4 are to blame. 2K confirmed they're working with Sony on finding a solution. In the meantime, 2K is encouraging PlayStation users to jump on the Xbox One or PC versions of the 4vs1 multiplayer game.
