Cunning achievement- Complete a level with the FBI

Tip- To get the FBI into the level you need to kill 2 cops

1- Choose the Halloween party with the normal guy
2- Kill the first few people using the torture traps to attract the cops
3- When the cop enters/leaves kill him with the horse, 1 down
4- Continue the level as normal untill there are 5 people left, (dont kill the cop again yet, we do this because it is easier to kill 5 people with the FBI than 15)
5- Next time the cops come kill him with the horse again, the FBI should now come
6- After killing the cop the second time go to the top right of the screen in the corner, The FBI wont see you up there
7- Kill the last few people, you will need to time your movements to avoid being caught
