When on the left side, go to the first long platform you find. Shoot a rocket launcher to kill your opponent quickly. Go as high as possible on the Blue Team and put a regular grenade with height as 27 and throw at 80% max. It will kick two enemies off the map. If on the red team, get on the peak of the rock. Aim straight, then shoot. You will kill one person. If on the same team, go over the rock and move forward slightly. Aim a grenade as high as possible and shoot it at about 90% to kill one person.
