GameBattles integration was first introduced in Call of Duty: Infinite Warfare in May of this year. The integration allowed players on PS4, Xbox One, and PC to link their GameBattles to the game itself, and then find GameBattles matches within the private match screen. GameBattles used dedicated servers for all of their matches in Call of Duty: Infinite Warfare.
SHG first mentioned GameBattles feature during gamescom, saying the feature would be available in the game. Now it’s confirmed to be available on Day 1.
