Overwatch is a Team Multiplayer First-person shooter developed and published by Blizzard Entertainment. Described as a “hero shooter,” Overwatch divides players into two teams of six, with each player choosing from a roster of over 30 characters, known as “heroes,” each with a unique playstyle that is divided into three general roles that correspond to their purpose. Players on a team work together to secure and defend checkpoints on a map or escort a payload across the map within a limited amount of time. Players earn cosmetic rewards that do not affect gameplay, such as character skins and victory poses, when playing the game. The game was initially released with only casual play, but competitive ranked mode. , various `` arcade '' game modes and a player-customizable server browser were added after its release.

Overwatch is Blizzard's fourth major franchise and came about after the 2014 cancellation of the ambitious massively multiplayer online role-playing game Titan. Part of Team Titan came up with the concept of Overwatch, based on the success of team first-person shooters like Team Fortress 2 and the popularity of online multiplayer battle arena games, creating a shooter hero-based that emphasizes teamwork. Some elements of Overwatch borrow assets and concepts from the canceled Titan project.
