Overwatch is a team-based multiplayer first-person shooter developed and published by Blizzard
Entertainment. Described as a "hero shooter," Overwatch assigns players into two teams of six,
with each player selecting from a roster of over 30 characters, known as "heroes," each with a
unique style of play that is divided into three general roles that fit their purpose. 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
only casual play, but a competitive ranked mode, various 'arcade' game modes, and a player-customizable
server browser were added after release. Additionally, Blizzard has added new characters, maps,
and game modes post-release, all free of charge, with the only additional cost to players being
optional loot boxes to earn cosmetic items. It was released for PlayStation 4, Xbox One, and Windows in May 2016,
and Nintendo Switch in October 2019.
