Rise of the Kasai

You will learn how to perform a stealth kill from above at the beginning of Mount Basuku and as such this is the perfect place to knock out this trophy. I recommend playing with Tati as this location is along the path the game wishes her to take.

From the start, head to her left and proceed to the West. You will head up some stairs where there is a small building. Go around the building and take out the 3 enemies that are on patrol. Afterwards, head to the far West side of that top area but do not jump down yet! Walk up to the edge slowly and the camera will eventually flip so that you are looking straight down. Below you there should be an enemy. Move to focus him and then press to initiate the stealth kill from above. The trophy will unlock immediately.
