From what little I've read so far, the game system is solid and I doubt the Unarmed Combat isn't likewise solid. However, there is no details on the martial communities of transhuman society. There are no details on martial arts whatsoever, especially transhuman martial arts. Sure, there doesn't need to be that kind of information in the core rule book, but at some point you'll need to detail the martial world (and perhaps detail Freerunning/Parkour in the same book). Maybe even add a martial faction or two.
