I have played the game completely through and I am wondering if there is any difference in the way you complete a mission. If you do it completely unseen do you get any sort of offset in XP for all the missed take downs knock downs? Does it have any impact on the story line like
Does it alter the scene where you save Jacks and he sees you kill all those people if you did not kill them?
I guess I am wondering if there is any replay added to the game other than personal challenge if I were to try a completely stealth/knock down only play through vs my last one where leaving people standing just appeared to give me less XP.
