47 kills-A mission has been completed with precisely 47 kills. 20 points

Accidents do happen... A successful accident kill has been performed 20 points

for more info on the special ratings check out this thread

Another Question. If I complete this game on professional diffiulty without playing rookie normal and expert will I get the achivemnt for all difficulties?

no you won't.

I know this from personal experience, but of course you get more points from beating it on pro

there is another secret acheivement if on "a new life" you steal the hedgecutters from that woman then kill everybody on the level, even the reinforcements, with it. i dont think it works on rookie, so just do it on normal cause its hard

whats the best level and stratergy to get the 47 kills one, and how do you manage to keep count and not die??

2 get da 47 kill's it is easyier on the theater level cause there is alot off people runin around. All ya gotta do is take every gun ya can wit ya on da mission then find a safe hidin spot and start shotin every1 ya see but keep count off how many ya hav killed and when ya get 2 47 kill's makin sure ya hav killed ur mission target's aswell but don't go any higher then 47 kill's or ya will just hav 2 start again, when done just exit da level though da doors ya started by and then ya will unlock it
