The Worn Pendant is the thirtieth treasure that can be found in Uncharted 2: Among Thieves.
The Worn Pendant is found in Chapter 7 - They're Coming With Us . The very first treasure of the chapter can be found at any time as soon as you gain control here, but we recommend waiting until the firefight has concluded before searching. You want to head towards the entrance point of the chapter. Once there, turn around and enter the courtyard again as if you were starting the chapter anew. As you go, keep an eye out for a blown out building immediately on your right. This treasure will be sitting atop a cardboard box in the corner of this building, underneath the window looking out onto the street.
