You will begin the level as Sam Fisher. Irving Lambert will begin talking to you via your earpiece. At this point, all you can do is look around. Lambert will instruct you to look at the four red lights set up around the immediate area (one is on the wall to your left, the other is to the right, the third is located on the ground while the final one is located up in the rafters). After completing the 'calibrations test', you will be free to move around Fisher. Move forward and jump on the ledge of the pull, and push up on the directional controls to move up over the pool. After this, Lambert will explain that he'll let you run the course.
