Since the mission One Of A Kind in Hitman: Absolution is a short, cinematic mission, there won’t be any challenge to complete, just a few items and disguises. The next mission, Blackwater Park comes with quite a few challenges to compensate the lack of them in the previous mission.
A lot of disguises to collect and use this time: the Blackwater bodyguard disguise can be taken from the penthouse enemy, the male ones. The Blackwater Custodian is got by taking it from the janitors. the Plumber disguise requires you to take out the plumber on the ground floor; the Samurai armor can be easily obtained inside the penthouse. The other disguises, the Blackwater receptionist, manager, interior, exterior guard and tactical team member can be obtained as usual, by taking one of them out and stealing their clothes.
There are two evidence piece to collect in this mission: the first one is in the Blackwater Park grounds, in the security office close to the flooded garage. The second one is in one of the corners of the room with the skeleton, on a sofa.
You know what you must do: no one must spot you at all.
No disguise use allowed.
You must find the movie reel and start the movie on the projector: you can find the reels in the rooms next to the projector room.
To clear this challenge you’ll have to hide bodies in the laundry chute. Keep doing it until the challenge is clear
