Mark and Execute

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 handguns and 9 mm with a silencer.

Instruction:
Aim at the target and press the Eng. M. you will see a green square (repeat to remove it). Then how to choose, click on. N GG 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 what the obstacle. It can be a car, wall, post, etc.
