This Grey Alien appears within the PC simulation game known as Signal Simulator.
This alien has a standard appearance to the common Grey Aliens: a Humanoid body with an enlarged head, grey skin, and large jet black eyes. While they have never been heard speaking directly, the noises they make when they infiltrate the Control Building reveal their language sounds similar to clicks, chirps, and croaks.
Very little is known of their behavior, though they have been shown to have a stalking behavior, as one of these Aliens can be seen via a security camera spying on the player within his own home as shown In the image on the left.
The aliens arrived on Earth at an unknown time via a mothership which they buried under the ground for unknown reasons. Ever since they have been terrorizing people across the planet, probing and experimenting on whoever they find. Sometime after that, the aliens abduct to coworker of the main protagonist.
