well, mine unlocked after i'd shot lenny in the head for like the 20th time, so maybe you dont have to finish the level then. you dont have to finish the level for challenges, ive quit/restarted checkpoint a lot doing these challenges and they all still count, so maybe its the same with headshots.
EDIT: also ive just found a little rubber duck just sat on a crate(the 'hitman' rubber duck, like my gamerpic
). i didnt want to start a new thread for it as it probably means nothing, but i just think its pretty cool.
