...yeah ok so the freeflow challenges are going to be a pain, with the predator ones, its just figuring out how to hit the 3 targets without dying, easy enough... the freeflow challenges, have to have massive variations (or at least 7 different move types in one combo for at least a 1k bonus at the end of the round), trying not to break the combo at all (flawless freeflow.. 1k per round), not taking any damage (as it also screws up your combo, but gives you a 500 pt per round bonus and a 5k bonus at the end if you make it the whole challenge w/o being hit). It all sounds easy enough until you factor in that if you hit any of the knife wielders without stunning them first... your combo dies, so you have to be aware enough to not do a regular punch on them, either a stun, throw or insta-takedown... and the controls are not always tight enough to not hit one accidentally. Oh and why I said all of this? It takes pulling all of this basically to get a 3 medal finish. And it takes all freeflow challenges at 3* to get to 24 to get the Freeflow Gold achievement, yikes.
