Hermes

Thanks for your response. Have you encountered one? Do they look like a crimson queen?

Does anyone know how I can encounter the xeno empress?? I sacrificed a private to a facehugger, and he eventually turned into a crimson queen, but didn't evolve further into an empress. Did I perhaps not wait long enough? Or does the queen never evolve into an empress? And in that case how does one encounter an empress? Thanks!!
