Overwatch is a team-based online multiplayer first-person shooter video game developed and published by Blizzard Entertainment . It was released in May 2016 for Windows , PlayStation 4 , and Xbox One .   Overwatch assigns players into two teams of six , with each player selecting one of 24 pre-defined characters , called heroes , each with unique movement , attributes , and abilities , whose roles are divided into four categories : Offense , Defense , Tank , and Support . Players on a team work together to secure and defend control points on a map or escort a payload across the map in a limited amount of time . Players gain cosmetic rewards that do not affect gameplay , such as character skins and victory poses , as they play the game . The game was initially launched with casual play , with a competitive ranked mode , various ` arcade ' game modes , and a player-customizable server browser subsequently included following its release . Additionally , Blizzard has developed and added new characters , maps , and game modes post-release , while stating that all Overwatch updates will remain free , with the only additional cost to players being microtransactions to earn additional cosmetic rewards .   Overwatch is Blizzard 's fourth major franchise and came about following the 2014 cancellation of the ambitious massively multiplayer online role-playing game Titan . A portion of the Titan team came up with the concept of Overwatch , based on the success of team-based first-person shooters like Team Fortress 2 and the growing popularity of multiplayer online battle arenas , creating a hero-based shooter that emphasized teamwork . Some elements of Overwatch borrow assets and concepts from the canceled Titan project . After establishing the narrative of an optimistic near-future Earth setting after a global crisis , the developers aimed to create a diverse cast of heroes that spanned genders and ethnicities as part of this setting . Significant time was spent adjusting the balance of the characters , making sure that new players would still be able to have fun while skilled players would present each other with a challenge .   Overwatch was unveiled at BlizzCon 2014 in a fully playable state and was in a closed beta from late 2015 through early 2016 . An open beta in May 2016 drew in more than 9.7 million players . The release of the game was promoted with short animated videos to introduce the game 's narrative and each of the characters . Upon official release , Overwatch received universal acclaim from critics , who praised the game for its accessibility , diverse appeal of its hero characters , bright cartoonish art style , and enjoyable gameplay . Considered one of the best games released in 2016 , the game received numerous accolades , including being awarded Game of the Year at The Game Awards , D.I.C.E. Awards , and Game Developers Choice Awards , as well as from numerous publications . Since its release , Overwatch has become recognized as an eSport , where in addition to sponsoring tournaments , Blizzard has announced plans to help support professional league play starting in 2017 .
