I just got lucky and stumbled across that pic, for superior trollin' effectiveness.
I have no idea where it's from.
But I'm still mad.
Part of me was actually thinking that, since there's a Sulaco level, the design team realized that if a tiny incision on the finger of a single facehugger bled enough acid to burn through 2.5 decks of the Nostromo, the hordes
of Aliens you'll be blowing away on the Sulaco would easily burn clear through the entire ship after you'd killed the first one or two.
Removing the 'acid' is an easy way to explain why this doesn't happen, though even if they kept it I doubt they would shoot for this level of realism. If you were that cool, you'd just make the entire level a zero-g sequence so the massive hull breaches wouldn't matter, or give the players alternate weapons like some sort of taser web to neutralize Aliens without compromising the ship. Hell, maybe even have the players trying to lure the Aliens into airlocks to blow them out.
But no, can't have that. No fun factor there.
