► What is Overwatch? ► Overwatch is a multiplayer first-person shooter video game developed and published by Blizzard Entertainment. Unveiled at BlizzCon 2014, the game emphasizes cooperative gameplay using a cast of various "heroes", each with their own abilities and roles within a team. The game entered closed beta in North America and Europe in October 2015, with plans to bring the beta to Asia at a later date. The final closed beta weekend began in April 2016 and primarily served as a stress test for Overwatch's servers, lasting 36 hours. The game was released for Microsoft Windows, PlayStation 4, and Xbox One worldwide in May 2016.
