The Terrain Scanner is a support tool universal to every class in the game. It is accessible by holding the Tab or M key on a keyboard, and Select on a controller. While the terrain scanner is activated, the player will be unable to move.
The Terrain Scanner will pop up on the player's screen for as long as the button is held down. The pop up reveals a manipulable, 3-dimensional interface of the surrounding terrain. In the center is the player's blip, displayed as a small arrow on the map.
Other players will be visible on the terrain scanner, the arrow representing each player changes color depending on which class they are playing.
- Driller is represented with a yellow arrow
- Engineer is represented with a red arrow
- Gunner is represented with a green arrow
- Scout is represented with a blue arrow
Remember what each color represents to identify your team mates.
The Terrain Scanner may also reveal the locations of your objectives. In Egg Hunt, all of the eggs will be visible on the Terrain Scanner as orange orbs. During extraction, the Drop Pod and its ramp is visible on the scanner as a large green cylinder and rectangle, and the M.U.L.E.'s markers leading up to the Pod will appear as small green squares. During a mission with the Haunted Cave mutator, the Unknown Horror will appear as an almost black orb. The Dreadnought Cocoon appears as a large orange ovoid. Waypoints created with the Laser Pointer tool will appear as a small dark-blue cube. The location for a Lost Pack appears as a pink star. Mini-M.U.L.E. legs appear as a pinkish/purple, while large ore chunks uncovered from a wall/floor will display as yellow pyramids. The communication uplink from Salvage Operation appears as a yellow version of itself on the mini map, while the fuel pod is a light blue cylinder.
