Resurrected will hold a closed beta starting Friday, August 13 for players who pre-ordered the game, and an open beta starting Friday, August 20.

Beta tests will be playable on all consoles and PC, except for Nintendo Switch, according to Blizzard.com. Xbox Live Gold is required for the pre-order beta on August 13 but is not required for the open beta on August 20. PlayStation Plus is not required for either beta test. Both Xbox Live Gold and PlayStation Plus will be necessary for multiplayer features at the game's launch.

Progress will carry over between the two betas, but no progress will carry over from the beta held earlier this year. Cross-progression will be available during both beta periods, but a separate pre-order is necessary for each platform during the Early Access beta. There will be no level cap for this beta, and it's unclear whether beta progress will carry over into the main game.Diablo II Resurrected Gold

Similar to a previous beta test, only Act I and Act II will be playable. The Barbarian, Amazon, and Sorcereress classes from that beta will be playable once again, along with the Paladin and Druid classes which are new for this beta. The game will launch with two more classes, Assassin and Necromancer, but those two classes will not be available during the betas.
