body mods do not seem to be part of the current build, however, they are mentioned because they are clearly a tangible good in the story which is why they are mentioned though not included.Is there a guide or some hints as to what each of the fragments do?
Also, characters keep saying about body mods, can they actually be bought or what?
As forwhat each fragments do it's hard to say, the first fragment you get gives you some ice power if you indulge in it and will slightly decrease your height with time. The second fragment lengthened the har and unlocked some ability that i think increases the amount of money you get from beating an opponent. The third fragment, at current, gives your character a more feminine voice
