Yep those rascally aliens that sneak into your cloest at night and replace your underwear with a couple of facehugger eggs.

What's funny though is that Prometheus actually kind of makes the opening of A3 plausible. If the xenomorphs are just dripping with that magic goo then maybe a Queen under distress can secrete some emergency "egg goo." Who knows.![]()

Prometheus isn't canon itself anyway
