Evidence Concealed Achievement
Hid 5 bodies in containers
Once you have taken out a hostile, you can hold when standing over their body to pick them up and to hide them in containers. A perfect location to start working on this achievement is in the first Mission, Safehouse. Once you are shown how Mark & Execute works and have taken out the three hostiles in the alleyway, enter the building on your right. Take out the next three hostiles and begin hiding all six bodies in the blue containers scattered around the ground floor. You can only hide one body per container, but there are four blue containers on the ground floor of the building and one in the alleyway just outside where you entered the building from.
