Hematic Weapons

hematic, adj.
relating to or affecting the blood.

Blood captures the imagination. Weapons of blood are popular in culture throughout the ages, from mythology to modern vids and vidgames. And the rise in knowledge of bloodborne diseases (such as hemorrhagic fevers like Ebola, or HIV) in the 20th century has crystallized a human paranoia of blood. The sight of blood can be shocking, even for immortals. And of course, technology can improve the "weaponization" of blood, with medichines and nanophages improving our natural defensive capabilities, or things like Defiler exhumans with their highly acidic blood. But blood and other bodily fluids are also a vector for the Exsurgent Virus. Exposure to the blood of an exsurgent biological strain can lead to contagion. Many transhumans are conceited in their security against potential hazards, but the horrors of the Fall have made people understand certain "TITAN made" super pathogens are still a hazard. In Firewalls SOP threads on the Eye, people weaponizing exsurgent blood is called "Hematic Weapons".

Most Exsurgents are not stable enough to actually think to use their blood, or other infectious matter, in a more technical and sophisticated way. If they are driven to spread the infection, they do so usually directly, such as through physical contact or other specific infection vectors. They aren't afraid to spill a little blood (if they have any at that stage), and might do so for big gains (such as tainting air, food or water), but subtleties and technical refinement tends not to be how the infected work. The contagious period will also eventually cease in the body, though if extracted the bio-nanos will remain virulent for days or weeks. They have specific forms and purposes, and AOK hacks tend to make one aim higher, but not always. Most often you see these weapons in the hands of TITAN puppets and sleepers, those who are not themselves infectious but already on the side of the TITANs, in the hands of various Singularity Seeker or Brinker cultists who have their own twisted agenda, or occasionally by criminal elements who don't know any better, such as rendering down exsurgents for parts and finding the infectious blood useful for their purposes.

The uses are many formed, but fairly obvious; since exovirus pathogens are applicable dermally, inhaled, injected or orally. The simplest is large samples of contagious blood in a sprayer, which is basically a squirtgun. This can be done with any infected blood, not even exsurgent, and some see it as a prank or a protest (and others, bioterrorism). More serious efforts will actually load the blood into capsule or splash rounds to strike a target, hopefully incapacitating them then infecting. With range and suppressors, this can even be quite subtle as to the exact nature of the shot, some may not notice the infectious component until it is too late. Some might even go a more extreme route, loading weapons with infectious bone marrow or other substances. For area effect though, aerosolized blood in a gas grenade or seeker is a good way to go spreading it to cover surfaces or be inhaled, the bloody mist being a powerful visual image. One might also spike melee weapons, such as the wasp knife, but considering the close contact this is often excessive when dealing with infectious material.

Firewall and other X-risk agencies always try to keep contagion in mind when dealing with the ex-virus. While the hematic tactic is not widespread, it is still a serious risk along with other more traditional methods, and one which could potentially be exploited by parties other than the TITANs themselves - something Firewall is always wary of. To counteract, an immunogenic coating is usually enough to forestall an infection, even an exsurgent one, especially if it has been outside of it's host for an extended period. Preventative nanoswarms can also break down the bio-nanos and render them inert, such as in the case of a spill. Other than that, simple physics works, exposure to potent acids or alkalis, or extreme heat will neutralize the effect. Always consider carrying some bleach if you think you'll encounter such things.

(Here's another Death Stranding twist. In the game, it's the players blood which is useful against the unknowable horrors, but in another context, using "special blood" as a weapon can be quite intimidating. A good way to freak out players who may already be paranoid about infectious material)
