After defeating the group of men and a cyborg wielding a Penetrator in a large room, go through the doors and onto a balcony with plants underneath. Use the ASP rifle to kill the two men that are attacking from below. Do not jump down to where they were as there is an very large cyborg with a multi-rocket launcher waiting for you. Instead, jump directly across from the doors you just came through and hide behind the first obstacle you find. Get out from your spot and shoot the machine with your ASP once to draw its attention so that it comes towards you. Once you get its attention, immediately get back to your hiding spot. When you hear it has stopped walking, lean out from your spot. It will not notice you, even after you start attacking. Keep shooting it until it explodes.
