xeno vs engineer (XvE)

from what i've seen so far, the engineers havent fared so well against xenos in the past...

considering the speed of SJs fleeing away ...the answer is the Xeno hands down :p

Xeno hardest creature in the universe ................FACT

We haven't a great deal of knowledge on the Engineers. They must have advanced weaponry, i.e plasma guns or something. If they had those, i'm sure they'd be superior to a Xenomorph.

That did kind of freak me out a bit when Janek explained that it was a military installation where they were making weapons of mass destruction. How did he know that? And if he was right, then why did the engineers not have any weapons or decontamination protocols? And why do their computer systems' user interfaces involve squishy play-doh buttons and flutes?
