You have to find the small pieces from the meteor 115.

The first one is in the room you start by the downstairs window, when you look straight at the window you will see a wall to the right. It will be right there, go up to it and hold X until one of the people say something.

The second one is in the room when you go where you go up the steps by the M16. You will see it on the shelf when you go up the steps.

The last one is by the MP5K when you look straight at it. Go in the room to its right and look straight at the window to your left. It will be on a pedestal in the little room.
