Since I don't use the steam forums, might as well ask here:

Finally got around to play this game (thanks again Cyrax), could anyone tell me if (a) completing challenges, playstyles and whatnot and (b) finishing the game on higher difficulties do anything other than getting the achievements? Do you unlock any extras or get something new storylinewise?
