How Diablo IV Couch Co-Op Works

wowhead.com:

What better way to cut through the legions of Hell than with a friend? Diablo IV brings back the well-received Couch Co-Op system from Diablo III on PlayStation and Xbox consoles with a few improvements! Couch Co-Op will be enabled on all consoles that support Diablo IV including PS4, PS5, Xbox One, and Xbox Series X|S. Using a screen-by-screen method, players will be side by side with their friends slaughtering hordes of demons — and the best part is, this can be tested during Early Access and Open Beta Weekends! Back in the day, Diablo III's Couch Co-Op allowed players to share item drops and adventure together on one screen seamlessly.

This will carry forward into Diablo IV, with a massive, much-wanted improvement — the restrictions on only one player having their inventory open at a time have been lifted.

This makes saving progression simple for players, leaving more time to enjoy the world of Sanctuary! While Couch Co-Op will only initially support two players, those with a full adventuring party can still group up via the 4-Player Co-Op system. All players utilizing this system must have official Early Access permissions, but even with this additional requirement, party play is worth it: Players in a party will get a small increase in experience based on the number of party members!
