Hey Levrault,
I just uploaded a new massive add-on for this character pack, which includes crouching attacks and a jumpkick (as a moving attack)
I still have some notes regarding attacks open, but the add-on actually covers a whole lot of requested animations and might be useful to you.
Check it out here:
