LaSalle, knowing that I'm an expert on Chimeran conversion technology, asked me to keep an eye out for anything that looked 'strange' to my eyes. He wouldn't give me details as to what Specter was hoping to find, but I can tell the Yanks know more than they're telling. While swimming through the Rotterdam sewer system I found a small area where the wall had crumbled away, creating an opening into what looks like part of a very old underground structure. The artefacts there look very old, and are definitely alien, though unlike anything I've seen before. I've marked the location on a map, which I'll forward to LaSalle when this mess is over.
