Navigation and Mapping Unit

The Navigation and Mapping Unit, or simply Nav Unit, is a hardware attachment found in System Shock. It is a radar-mapping system that records where you have been. It records walls, doors, and other objects of interest, and is keyed to the Citadel Station’s shuttle navigational beacon. A directional indicator that adopts conventional compass directions shows which way you are going.

Usage
To use the map, press the appropriate Side Icon or "7" to activate or deactivate the navigation module’s compass feature. Select the "AUTOMAP" button in either MFD. This displays a close-up view of the map, with your current position appearing as a red triangle. As you explore, the module expands the map and the position marker moves.

The two buttons at the bottom of the MFD identify map views. Both maps have buttons that perform different map functions. The SIDE and FULL buttons switch the map to cross-section and full-view modes, respectively.

Select SIDE (lower left) for a cross-sectional view of the Station in the MFD. Once you click this button, a cross-section of the Station displays and "SIDE" changes to "ZOOM". The level you are currently on is highlighted. If you press ZOOM, a close-view of the map reappears.

Select FULL (lower right) to display a full-view map of the level and a menu of map options. This mode fills the entire screen and pauses the game. The buttons on the right perform various functions.

Entering Comments
You can enter comments in the full-view map. To enter a comment, click on a location on the map and type a text message (it displays on the bottom of the screen). Then, press "E". Select "DONE" to return to the view screen.

When you return to gameplay, each comment appears as a floating tetrahedron in the view screen, in the corresponding location in real space (if it can be reached). To read a comment, find a tetrahedron. Then, double click on it to read the message. Alternatively, open the map and left-click on a blue square in the full-screen or MFD map.
