Blizzard has announced that the cross-play update is now available on Overwatch for all platforms.
To play with other platforms, you’ll need to link your console to your Battle.net account. Crossplay is sadly not available in the Competitive mode. it is however in Quick Play, Arcade, and Custom. All players that log in during 2021 will be gifted with a Golden Loot Box, which as you would guess gave me a skin I already own. Thanks for the currency I can't use until the next event.
Lastly, the update came with a new limited-time Ashe’s Deadlock Challenge event but they've made unlocking the skin take longer with it now being 27 played matches with a win counting as 2. Players can earn rewards such as player icons, sprays, and a Legendary Deadlock Ashe skin before the event ends on July 5.
The cross-play update is for Overwatch on Xbox One, PlayStation 4, Nintendo Switch and PC.
