EA Games has launched the first Closed-Beta for Mirror’s Edge Catalyst, which will be released for the PC, Xbox One and PlayStation 4 on 24th May, 2016.
The beta page suggests that it will be available on Origin for PC, along with Xbox One and PlayStation 4. It will require a persistent internet connection too. You can sign-up for the beta here.
There’s been no release date set for the closed-beta, but it should be happening fairly soon with the games date set for 24th May, 2016.
