2K Games and Turtle Rock Studios have deployed the Big Alpha for their upcoming 4-v-1 multiplayer romp, Evolve. At least they have for most platforms, anyway. They didn't foresee any of the issues that would suddenly pop up on PlayStation 4, which has now caused 2K to postpone the alpha on that platform indefinitely, due to issues with the recent 2.00 firmware update.
"We have some unfortunate news to share with folks planning to participate in the Big Alpha test on PlayStation 4 starting today," reads a post on the Evolve website. "Following the recent PS4 2.00 firmware update, we are experiencing difficulties with the Evolve Big Alpha on PlayStation 4. As a result, the test on PlayStation 4 is postponed. PlayStation and 2K are working together on a resolution."
2K is encouraging PS4 users to jump on Xbox One or PC to get in on this weekend's fun. Otherwise, they will offer updates as they come.
