Those aren't typos, they're pedantry Adamant, adamantite, adamantium, etc. are fictional/non-exact terms, used variously to describe metals, ores, and crystals. "Adamantite" was chosen by American Biologic Inc. (a subsidiary of Apple) in 2066 as a branding term for a new product in its "Bionic Fury" line, both for its recognizability and its appeal to comic book nerds. And yes, it's comic book-y, which is wholly appropriate for the game as it stands. It is a video game about zombies and aliens from another dimension. I think we have been over this.
If you're describing a metal, you don't want to use "ite". If it's just a brand name for something it doesn't matter much, but if you're specifically naming a metal then you don't want "ite" because that's the standard for naming a stone/mineral. It's pedantic, yes, but honestly it's pretty objectively weird to name a metal/alloy that way (nor have I ever seen the fictional metal named like that) and it's an easy fix.
After a bit of googling, it seems that "adamantite" is used by some fantasy games for naming metals, but "adamantine" or "adamantium" would still be preferable (fantasy authors don't exactly know what they're talking about much of the time).
Not sure where flu meds are referred to as antihistamines. Grep turned up nothing when searching for "antihi".
It's in bionics.cpp in the section dealing with what I believe is the blood analysis bionic. Then again, I was probably looking at the aposos source, though I have no idea why that would differ.

Chitinous helmets could use a boost, huh? I'll perk up their stats a bit. They are intended to cover the eyes, with a small slit for seeing through. The helmet's highly encumbering because it provides high levels of coverage. The armor is so encumbering because it's un-processed chunks of animal carcass sewn together.
More unprocessed than the leather you get from zombies? I figured that if you can use raw leather from undead critters to make similar-to-store-bought clothing, that the chitin is treated in some way, being boiled or cured and molded into shape somehow, which would be the most sensible thing I can figure. Besides, you're making it yourself, so the plates are suited to your frame. Also, I was under the impression that eye coverage also protects you (at least in theory) from things like harmful chemicals and vapors, which eye slits wouldn't do very much for. I could be wrong.
Really though, at 4 encumbrance I just don't see anybody using it. Melee players will want to run faster and ranged players will want to be able to shoot effectively. Motorcycle helmets aren't hard to find, and by the time you can make them you'll probably have found riot helmets as well, which are better. As for the armor, the fact that it covers the legs is useful, but that's about it; otherwise, you'll just want to use kevlar, which is both capable of being repaired and something you'll probably have already if you have high skills and can kill giant bugs successfully.
