Sectoid (Bureau)

A slave race (who's iterations will be tied to XCOM's (and Earth's), future for years to come) under the control of the Outsiders, these Grey aliens are numberous, fairly weak, and easy targets. But, they seem to be under the more direct command of a higher intelligence, which drives them to surprsingly clever tactics, including cover fire and flanking.

Having no additional abilites, and only wielding pistols (starting with Laser pistols, and eventually upgrading to Plasma varieties), they focus more on superior numbers to swarm XCOM agents. Having small, almost childlike bodies, they need to nearly climb over their own cover to be able to fire at Carter and his team. Plus having massive heads, it's fairly easy to dispatch them with small-arms fire, or a single headshot from nearly any weapon.

Autopsy Report: Sectoid

"The So-called "Sectoids" - also called "Grays" by the field agents - are small, weak humanoids are recognizable by thier large craniums, eyes, and otherwise stunted physiques. Specimens lack visible mouths or nostrils, and exhibit only minimal respirator or digestive systems, raising significant questions about their metabolic processes.

"More curious then their anatomy, however, is the collars they are always found wearing. In addition to acting as physical restraints, these devices act as neural interface, transmitting both simple communication and basic sensations, most specifically pain.

"Through this, we infer that the Sectoids are a slave race to the Outsider, used as expendable troops and menial labor who resuire minimal nutrition or care. Whether they were a prior ocnquest or manufactures whole-cloth for this purpose, this is an ominous sign of the Outsiders' intentions for conqured reces - including Humanity."
