Awesomenauts just launched patch 2.3 dubbed The Secrets of Space. This patch is one of the largest the game has seen. This patch has some balancing tweaks for each character, some graphical tune-ups, and the usual bug fixes.
But the biggest addition is for those who have the Starstorm DLC/expansion. They get access to a new character, Penny Fox, a mobile melee character who relies on earning charges to unleash her powerful specials. She joins Ted McPain as a Starstorm exclusive. Along with some new custom match options and the promise of new characters and features to come, I can now recommend whole-heartedly dropping $9 on the expansion at this time.
