Ares was the codename of a canceled first-person shooter set in the StarCraft universe.
The game was described as Battlefield in the StarCraft universe. Builds were constructed where players, as terran marines, could gun down zerg. Plans were made to allow for players to also play as the zerg. It was designed in the Overwatch engine, and led by Dustin Browder. It was planned as an experiment to see if it was possible to use the engine for multiple games, in order to speed up Blizzard's development cycles.
The project had been in development since 2017 according to some sources. It was canceled early June 2019. Games journalist Jason Schreier interviewed at least three Blizzard staff members under condition of anonymity as to the nature of the project. One stated that development progress had been slow, while a second said that the cancelation had come as a "massive shock." A third said that it was "looking quite good." Blizzard itself released a statement in regards to the game's reported cancelation, writing "we always make decisions about these things, regardless of the ultimate outcome or how things might be interpreted, based on our values, what we believe makes sense for Blizzard, and what we hope our players will enjoy the most." According to two staff, Ares was canceled alongside an unannounced mobile game, so that the staff could be transferred to work on Diablo IV and Overwatch 2.
