No idea what these do, but they appear to follow the same setting system of (Easy,Normal,Classic,Impossible). More information is needed. FragmentBalance=0.25 FragmentBalance=0.25 FragmentBalance=0.25 FragmentBalance=0.25 these control the weapon fragment amounts for each difficulty. i set mine to .75 and swimming in weapon fragments now. .35-.45 would probably be closer so you have enough for projects but not a bunch extra.
