Blizzard just announced Diablo 3's Open Beta weekend. If your anxious as I am to give Diablo 3 a try before its worldwide release on May 15, here's our chance. As long as you have a valid Battlenet account, you can join in on the open beta this weekend.
You can start downloading the client now and start playing Diablo 3 this weekend. You'll have access to all classes but only able to progress up to level 13.
The open beta is from From Friday, April 20 at 12:01 p.m. PDT (noon), until Monday, April 23 at 10:00 a.m. PDT.
This for me is considered a demo of the game since the game is less than a week away from release.
