The Reborn beta is now available for everyone to download and play. Check out the update page[www.dota2.com]
for installation instructions and to learn about a number of new technologies that we're using to improve Dota 2.
Unlike our traditional Test client, your match history, MMR, cosmetic items, and friends are shared across the two versions. However, Ranked Matchmaking is not enabled yet. We anticipate that we'll be able to turn it on in a few days, but we need more testing of the basic functionality first. Also, it is possible new items may make their first appearance in either the beta or the main client. These items may be temporarily missing from the other client while their assets are converted.
As you explore the beta, you’ll notice a few features aren’t fully functional yet, but we encourage you to play regularly and send us your feedback. We'll be updating the client frequently over the coming weeks as we bring everything online.
