Aaron Keller, who has replaced Jeff Kaplan as game director of Overwatch and Overwatch 2, has announced plans for cross-play in Overwatch, allowing PC and console players to play together. Everyone will also be given a Golden Loot Box when cross-play becomes available.
In order to participate in cross-play, console players will need to make a Battle.net account and link it to their console account. Details on how to do this is available on the Overwatch cross-play FAQs page.
While cross-play will be coming to Overwatch, cross-progression will not be available “at launch,” with Aaron Keller stating that “it’s something that the Overwatch team is excited to work on in the future.”
How cross-play actually works in Overwatch isn’t as quick and easy as “everyone can play with everyone.”
By default, a party of console players will play with other console players. A party of PC players will play with PC players, as well as groups that consist of both PC and console players.
If you’re a console player and you solo-queue into Quick Play with cross-play enabled, you will be matched with other console players and not with PC players. If you are a console player and you form a party with console players and PC players, you will be placed into the PC matchmaking pool and play with PC players, as well as groups that consist of PC and console players.
As a console player, if you disable cross-play, you will be match-made only with players from your particular console.
Please note that PC players cannot disable cross-play.
It is also important to keep in mind that cross-play will not be available in competitive matchmaking, meaning that they will have their own matchmaking pools. Furthermore, leaderboards will be separate between PC players, cross-play enabled console players, and cross-play disabled console players.
