UPDATE: November 2022
Added 2022-11-28 23:20:40 +0000 UTCDevelopment is coming along slowly, but surely!
Some new developments in Universal Fighting Engine 2 (Which is what both Blueblood games are currently using as a base) has helped improve Blueblood Breakdown. These changes to UFE2 have not yet been implemented into Blueblood Arena, but will be soon.
As you may know, there are 7 currently revealed characters for Blueblood Breakdown. I do not believe we will prioritize porting all of these characters over to Arena, our current priority is finishing Enza and Amber. Hopefully, these two will be finished fairly early on into the new year.
Amber is closest to being done, with only a few moves and poses needing to be animated, with Enza in a state where all basic animations are finished, but we're only now starting to animate attacks.
TLDR: We're workin on it!
