Update 2.3, which we have dubbed “Secrets of Space,” is one of biggest updates we have ever released for the Awesomenauts. In addition to the new playable character, it brings an incredible amount of balance tweaks (with all characters receiving some balance love), three new skins (including the long-awaited and oft-rumored Cynical Vinnie skin), a new in-game song, and a substantial array of improved graphical effects. The patch notes are over six pages long, and you can read up on them over here.
Let me give you the short version of it though!
