Team 1 is a designation for one of the internal development teams of Blizzard Entertainment. As of November 2018, it consists of anywhere between 100–300 individuals.[1]


Team 1's existence (in terms of staff, the name was coined much later)[2] stems back to at least 1994. It is primarily concerned with box products. The original StarCraft was produced by Team 1.[3] They subsequently worked on Warcraft III.[4] More recent products include StarCraft II and Heroes of the Storm.[3]

In 2015, the StarCraft II element of Team 1 was divided into at least two sub-teams. One focused entirely on e-sports and multiplayer. The other focused on singleplayer. Other team members also worked on the Arcade.[5] As of November 2018 however, the team appears to be predominantly based around Heroes of the Storm.[1]
