Animations aren't all polished and there's still plenty of balance problems to work out, however, the more recent versions are actually quite playable. While we are, in fact, stuck on this version, this version of Rack 2 is actually quite playable. So, we are stuck with version 2.12 for quite some time now. Unfortunately, that has been taking much longer than expected. As of now, the focus has apparently been on multiplayer development.
Rack 2 has been in development for a while. So, maybe add something probably worthwhile to read as well? I haven't added a journal lately and I figured it was about time I added something.
