With the release of cross-play, all players will need to create a Battle.net account to link to their console accounts. Additionally, everyone who logs in to Overwatch by the end of 2021 will receive a “Golden Loot Box” to celebrate.
Cross-play will launch in the beta phase. The Overwatch development team will be monitoring feedback and look to make improvements on the feature moving forward.
