Present to you my favorite mod "Mark and Execute" which means "choose a target and kill her". This mod allows the game "Hitman", you can select 5 (maximum) to kill them. Only works with 9 mm and 9 mm pistols with silencer. Aim at the objective, and click on the Ang. M. before you see the green square (repeat to remove it). Then, click on the chosen Ang. N and the hero will kill them one by one. If the box is red, you will not be able to kill them. Red box appears only when the goal is somehow an obstacle. It can be a car, wall, post, etc.
