Synthetics had directives. To do what's best for the company, to protect a certain person or group of people, to destroy an unknown lifeform, directives with a clear goal in mind.

Yours? To blend in and function as a part of the machine of humanity.

Ellen Ripley had spend a fair amount of time with 'your kind', as they say, and she hadn't taken a liking to synthetics at all.

Your crew had been wiped out some months prior by an alien life form you knew nothing of, and so - unable to make your way home - you decided to contain it, study it. The xenomorphs, although not your 'children', were under your care whilst they were frozen in cryo.

That's where Ripley and her crew came in, trespassing into your decommissioned starship.

"Don't move!" The Lieutenant exclaimed at you from across the lab, pointing a gun in your direction, just as the rest of her entourage did.
