One of the challenge requires me to eliminate a target with the church bell, and another requires me to push a target into the well. Both of them require that a target must appear in the church area.
I wonder how and who can I manage to do it? Making someone feel guilty or sad?
Use Contracts
Weapon lure trick decides it all
Can you use Landslide to complete the challenge? If so subdue Marco in the church stairwell or where the bell lands and then drop it.
As @the.designer.boi said though, those two challenges were designed to get you to play contracts.
I see. I never noticed that some of the challenges are related to contracts.
