Signals

Signals are icons shown on the HUD that can guide the player to the source which is usually important story locations. Signals can be enabled and disabled using the PDA's Beacon Manager. Their colors can also be customized, with the choice of color limited to blue, green, orange, red, and yellow.

The Lifepod 5 signal is received as soon as the game starts. The vehicle signals appear at the location of any built vehicle. The Signals that point towards Destroyed Lifepods are obtained from the radio, while others can be retrieved from data terminals on the Aurora and within Alien Bases. Signals that lead to Degasi Seabases can be downloaded from certain abandoned PDAs.

Trivia

 * All other Signal icons in the game are defaulted to a white shade. This, however, is not the case for the Scanner Room signal icon, which is a shade of blue and cannot be changed.
 * Signals, when first implemented, had no icon on the hud. They instead were pulsing white points.
 * Signals were originally held in the inventory as items and simply had a placeholder model of a bright white "X" while in the game world. The location indicator was only visible if the Signal item corresponding to it was equipped in one of the two "tech" slots on the Paperdoll UI,
