We just released the third Open Beta (version number Beta 5A) for Awesomenauts 3.3: Rise of Galactron on Steam!
The new Beta includes the all-new Fan Art gallery, improved performance, and resolves a large number of connection issues and other problems players encountered. If you ran into problems with the previous Betas, please test out the new Beta to see if they've been resolved and let us know about it!
In addition to the improvements, the new Beta also features several new balance changes that we're planning to release in Update 3.3. For the full patch notes and list of balance changes, head over to our official forums: http://www.awesomenauts.com/forum/viewtopic.php?f=19&t=46832
Thanks for testing! If all goes well, we might be starting to run more tests in the 'live' environment soon, which will mark a new phase in the release of this massive update!
