Xenomorph/Headcrab Defence!

[Chibz]

My defense would be ... Being Overlord Laharl.

Spoiler

Whatcrabs? They DARE try to assassinate the great and mighty LAHARL?!

AH HAHAHAHAHAHAHAHAHAHA!

for Half-Life I would think the head crabs would be able to figure out how to tear off a helmet.

If you duck underneath an enormous, conspicuous shiv of spinning, sharpened metal, they will jump at all too willingly, after which they will promptly suffer a fast and thorough dose of Karmic justice exercised upon their fragile little bodies.
Hell, if you stand 10 feet above a room full of them they'll leap and leap endlessly without any regard for the stacked-up piles of boxes nearby that could give them access to your face. I know what you're saying here but, given that the intelligence of a Headcrab is limited to jumping, eating and (to a certain extent) inseminating, I really don't think they could. Duct-taping a kitchen knife to a wok and donning it rice-picker style would probably do a half decent job of keeping the little bastards off your head.

As for Facehuggers... they do bleed acid, so that's a bit trickier as the knife wok idea more or less expires (along with your skin) on impact. I dunno, some kind of large metal box? Or maybe just better training against them? Teach every Marine how to catch or avoid a Facehugger mid-jump[footnote]I'm thinking Dodgeball-esque training: "If you can dodge a wrench you can dodge a ball!"[/footnote] and that should help a lot. Probably.

Facehuggers can spit acid/blood onto thier victems, it wouldnt matter.

There is a such a thing called "acid resistant metals" you know. It may not block it 100%, but its better than nothing.

In the first few alien films I don't think humans had any kind of usable material that was resistant to the xeno acid. If I remember rightly anyway.

The Yautja had a few weapons that didn't seem to be effected by the acid in the first avp film though. So I never got why they didn't make their masks out of that stuff.

Maybe they were made of plastic or a composite. They tend to have high acid resistance.

But this is space acid were talking about, it is highly corrosive and could be way worse than anything on Earth, so having an acid resistant metal to the acids on Earth may prove terrible against the Xeno acid.

I guess developing an entire new helmet to combat a special new force in a few days with no tools to do so is pretty hard. I mean they could wear proper masks but that would probably still be burned through by the Xeno acid.

space acid =/= magical acid that burns through everything.

It still follows the same rules as other acids, and can be countered.

It can follow the same rules as acid on Earth, but still it is a strange, untested, unknown acid that probably has a lot higher lethality to it than acids on Earth. Remember in the first Alien movie when the acid from the face hugger nearly burns every single layer of the steel platforms on the sheet really quickly, I don't think any Acid on Earth can do that, except maybe Nitric Acid, but I doubt it could do it as fast and in such small amounts.

However, that metal was most likely not treated for acid. it would be absurd to treat metal for acid in all applications. It was never intended to be a battle ground for aliens.

Yes thats true but...

It is still steel, steel that must be thick, dense and strong enough to support people walking on it and to hold up various equipments and things. The outer of the ship must be strong enough to survive traversing space and planetary atmospheres, so that would be extremely strong and durable too. We could also assume that this is based somewhere between the near future and the far future considering we don't have any of the space crafts available like they do in the movie, our space ships can't just land when ever we want them too, it is all done extremely carefully. So if this is in the future it would be a pretty easy assumption that the metals and steels that are used would be stronger (if slightly) to the metals and steels we use in space ships now.

Then there is no acid, that I know of, on Earth that can easily burn through steel so quickly, some can but they take a long time, others won't at all. So basically you have an extremely corrosive acid that can burn through A grade steel in seconds and burn through layers and layers of more A grade steel. So the acid is still extremely stronger than anything on Earth therefore if soldiers were to wear helmets that acid would completely destroy them anyway, so defense from the Acid is futile unless you have something designed to resist against extremely corrosive acid that you can fit on your body, or you basically get a 2 meter thick piece of steel.

like my working shoes! lol.
eveyone! wear your shoes on your head! XD ( woo natural selection, no more people in flimsy winmsy flipflops that they dont tie the laces on XD )

and yet it had no acid treatment. Steel is not some magic metal that resists all things. In fact, it falls apart in moist atmospheres. Its a crappy alloy against corrosion, and might as well be cardboard. Steel is used because its cheap, and is strong enough for most applications. Nowhere in there does it say its corrosion resistant in any way.

except that it doesnt melt through IN ONE GO, instantly the moment a face sitter farts acid at you.
it might go through, in oh, maybe 3 hours.... and yes steel corrodes in atmosfere. the outer layer. eventually it slows down more and more and more so the core will be good for QUITE some time..
