Overwatch puts players into two teams of six, with each player selecting their a character from a varied selection known as "heroes", with their own unique abilities and powers. The two teams work against each other to complete map-specific jobs within a short time span.[1] Blizzard 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 purchase cosmetic items.
Overwatch is Blizzard's fourth major franchise. Its origins came after a massively multiplayer online role-playing game, Titan, was cancelled. The developers of the game based it off other first-person shooters, such as Team Fortress 2. Some elements of Overwatch borrow concepts from the canceled Titan project.
A sequel, Overwatch 2, was announced in 2019, and released on October 4, 2022.
