HUD

The HUD or Heads Up Display is a graphical interface overlayed onto the screen to give the engineer information. It includes a cross-hair, compass, hotbar, the hotkey tool-tip, healthbar, and equipment status.

Compass
The compass shows the cardinal directions relative to the engineer's current facing and also indicates the directions of vehicles with an icon. It also shows the direction of waypoints from the HUB or beacons.

Hotbar
The hotbar is a list of numbered slots, similar to hotbars found in many other games. Placeable entities such as vehicles and buildings can be placed in the slots, allowing them to be selected and placed.

Tool-tip
The tool-tip menu lists several tool icons and their associated hotkeys. It seems to list the following:


 * Q - Build Menu
 * F - Demolish
 * V - Flashlight
 * C - Resource Scanner
 * X - Codex
 * Tab - Inventory
 * Z - Map

Vehicle status
This is displayed when the engineer is piloting a vehicle, and gives information about that vehicle, including its current fuel, and an unknown blue bar.

Photo mode
Pressing the "P" key will bring up the photo mode, which removes the HUD elements, and allows changing the field of view and toggling of a Hi-Res mode.
