It takes place in 2497 if I'm not mistaken.
So we can dream about a lot of Alien movies between 2104 and 2497. :)

Interesting find! I am not familiar with the compound. Based on the periodic table, I believe fluorine is in the same group as chlorine? I have noticed inconsistencies with how that blood reacts throughout the series LOL! Aliens comes to mind although I love it nonetheless.
All said, if it is a strong acid for blood, an effective weapon would seem to be one that could penetrate the body with a basic solution to neutralize the acid? Gotta brush up on the ol' chemistry classes. I do know that experimenting with hydro chloric acid and water as a kid yielded nasty results. Boring summer days with swimming pool water maintenance duties- what could go wrong lol!

I work with HF, It is friggin nasty ****, but Alien blood it is not.
Hydrofluoric Acid is ridiculously corrosive to organics and metals, but is considered a 'weak acid' due to its low dissociation constant.
Essentially it penetrates skin and flesh, strips calcium from the bones then works it way back. If you've watched Breaking Bad season 1 where they dissolve the body in a bathtub slowly over a week until its a goopy liquid mess.....HF.
Wipe or wash it off and it keeps burning!! Calcium Gluconate is needed to stop the reaction. Nasty, nasty ****!!
Hydrofluoric Acid also attacks silicates, which seems to go against the chitinous exoskeleton of the Xenos.
Science *****es!

ooooooooooooo some calcium gluconate needed for those burns me thinks lol
