Faces of Deat is started when you talk to a man named Nero in Badtown. He'll ask you to take pictures of the dead enemies outside of town in order to show the people in the village that the pirates can be killed, and to stir up revolt
Photograph all of the ambushed pirates.
Return to Nero with proof.
In order to complete this mission, you must take pictures of three pirate bodies that are scattered around the outside of the town. The bodies can be somewhat difficult to find, because they mini-map indicator may give out at some points, but a nice feature on the camera helps you ou some. Whenever you direct your camera a a dead enemy, the targerter changes color and becomes darker. It will also make a quick sound. Scan the ground and look/hear for these changes, and soon you will find the bodies.
You may run into enemies, but they shouldn't be too difficult; at most, there will only be five, and spread out across the area at that. Just pay attention to where they might be and you should be fine. Once you have collected all of the evidence, bring the pictures back to Nero. He will say that he needs to "analyze" the pictures alone before releasing them, and you just take your money and leave.
