You’re sick and tired of those kids playing football on your lawn. Time to teach them a lesson.
Right click anywhere to get your gun out and shoot the kid next to the goal. Shoot the arrow to go to the next part. Shoot all three kids, shoot the one on the right twice. Then shoot the arrow to move on.
The goalie is armored. Shoot on the arm pads first, then on the arms. Shoot both the legs, then in between the legs. When the kid is exposed, shoot him in the face to finish the job.
