Overwatch is an upcoming multiplayer first-person shooter in development by Blizzard Entertainment. Overwatch will feature squad-based combat with two opposing teams of six players each. Similar to a multiplayer online battle arena game, players choose one of several hero characters, each with their own unique abilities and role classes: they include offense-oriented characters with high speed and attack but low defense, defense-oriented characters are meant to form choke points for enemies, supports that provide buffs for their allies such as healing and other boosts, and tanks that have a large amount of armor and hit points to withstand enemy attacks. Players can switch between characters in-game following deaths—a mechanism which is encouraged by the game's overall design.
