Evolve‘s “Big Alpha” test is now live on PlayStation 4, publisher 2K Games announced, after resolving problems introduced by last week’s PS4 firmware update. The alpha event for Evolve is also being extended for all platforms — Windows PC and Xbox One included — through Tuesday.

“We believe we have addressed the majority of known issues affecting the Evolve Big Alpha on PlayStation 4 following the PS4 2.0 firmware update,” 2K Games said in a statement an hour ago. “The alpha test is now live on PS4 after a gradual roll out to registered participants. Evolve’s closed alpha test is also being extended on Xbox One, PC and PS4 through Tuesday, Nov. 4 at 3 p.m. ET.”
