Velonaceps Calyx (Also known as the “Husk Infection”) is a commonly feared parasite, that can kill a whole submarine’s crew if handled incorrectly. However, it is quite easy to deal with if you know what to do.

WARNING: This guide contains spoilers to some parts of the game.


Broad-Spectrum Antibiotics are a cheap solution to husk infection. Antibiotics give you the “Husk Resistance” effect, which slows down the rate at which the Husk parasite can grow.

However, Broad-Spectrum Antibiotics are bad at actually reducing the Husk infection. They require a high medical skill to effectively reduce the infection, so it’s best to use it right after you get infected by the parasite. On top of that they also cause Organ Damage, which requires Morphine to be administered some time later.


Calyxanide is a great option for killing the Husk parasite completly. If used by an inexperienced crewmember, it can have a reduced effect which could require another dose or Broad-Spectrum Antibiotics.

Calyxanide is an effective option for treating Husk, but it is also costly to both buy and make. Calyxanide can also be used as a weapon against Husks, it causes major Internal Damage when applied on one.

Other ways

If the crew doesn’t have any Calyxanide or Antibiotics on hand, it’s likely that more unusual measures will have to be taken to prevent the parastite from spreading.


If the infection hasn’t progressed far enough, Weapons can be used to… dispatch the threat. The same can be done when the Husk has taken over the host.

Medical Clinic

Husk Genes
