If you have an active World of Warcraft subscription, you can jump into a Classic server tomorrow for testing.
Blizzard is hosting a limited-time stress test for the upcoming World of Warcraft: Classic beginning tomorrow, June 19. The test is only available to subscribers in the Americas, and Oceania.
The download should go live today, and servers will follow tomorrow at 2pm PT, 5pm ET. It'll wrap up on Friday, June 21.
During the test, you'll have access to all races and classes. The level cap is 15, but you'll be able to play open-world activities as well as instanced content such as the Warsong Gulch for PvP, Ragefire Chasm, Wailing Caverns, and Deadmines.
"Please focus as much play as possible during the first three hours of the stress test. During this time, we’ll be looking for more issues to address under initial launch conditions," Blizzard wrote.
You can use the in-game tool to report bugs.
World of Warcraft: Classic launches August 27 on PC.
