Once Sir Dan has reached the Professor's Lab following his exit from the Museum, you'll then receive successive access to all the other areas in the game as he completes each area and becomes eligible to enter another. Have Sir Dan head for the Professor's desk whenever he next arrives in the lab after completing an area. On the first visit, Winston will introduce Sir Dan to the Professor, where on the first and subsequent visits, the Professor will impart valuable information concerning his most recent activities.

The inventory bench is found to the right of the Professor's bench. When Sir Dan brings a completed chalice (i.e. 100% of the requisite bad guys have been vanquished) to the inventory bench, the Professor will exchange it for a new weapon.

The projector, to the left of the Professor's desk, will show different London scenes of the places Sir Dan is currently allowed to enter, when Sir Dan steps on the left most floor plate. If there's a chalice associated with the area, the chalice will appear on the clock in the upper left corner. A red "X" will be shown upon it if you haven't yet obtained the chalice for this area, or a green check mark if you did. Press the 'Left' and 'Right' directional buttons to step through the currently accessible areas. You can press the 'Square' button to hear a briefing regarding the area being shown. Pressing 'X' will result in entrance into the area, while pressing the 'Triangle' button will cancel the display of the area.
