Diablo 4 is coming to Steam on Diablo 4 Items October 17, the same day Diablo 4 Season 2 launches.

Blizzard announced the Steam version of Diablo 4 during today's developer update. Both crossplay and cross-progression will be supported immediately, which means Diablo 4 players on Steam will be able to play with everyone on all other platforms - including PlayStation and Xbox - and continue their saves across all platforms.

It's worth noting that if you're picking up Diablo 4 for the first time on Steam, you'll still need to connect it to your Battle.net account to enable cross-platform play, same as all Blizzard games. Otherwise, you'll be able to play the previously Battle.net-exclusive action RPG just the same as any other Steam game, complete with Steam achievements and full friends list functionality.

Diablo 4 devs know they've been "a bit quiet" on Season 3, but will have Diablo IV Items details to share "very soon" | MMOEXP
