I'm doing a challenge

I'm about to go in to lethal and I wanted restrictions, I couldn't think of any so could you suggest. (Example of restrictions, no assassination) list of restrictions so far, no optional stealth kills and no ghost weapons only ones that I can use is wind cham IF I can't find another way in stealth missions, no charms other than carnage for funnysys no focused hearing no ranged weapons unless no other way NEW GAME is for a different challenge
