Unveiled at BlizzCon 2014, the game focuses on cooperative gameplay using a cast of various “heroes”, each with their own abilities and roles within a team. The game entered the closed beta in North America and Europe October 27, 2015, with plans to put the beta in Asia at a later date. The last weekend of closed beta began April 15, 2016 and primarily served as a stress test for the Cartel servers, lasting 36 hours. The game is scheduled to be released May 24, 2016, on Microsoft Windows, PlayStation 4 and Xbox One.
