Utility Supplements

Optional Expansion: Adds various utility items. (Note Medical Supplements mod is required).


This mod will be used to add various additional items of varying nature that can be of practical benefit but not considered as medical or social supplements.


A genetically modified flower that gives off an awful toxic smell. It uses a localised toxic gas defence mechanism in an attempt to defend itself. This can have a poor effect on your colonists if they breath in this gas for any length of time; it can effect breathing and consciousness amongst other unpleasant things, raiders, other NPC faction members and animals (that can breathe) will equally be effected, but animals tend to flee from this plant. (Note animals following a master will not flee).

The leaves it produces are not very nutritious and highly toxic. These properties can be chemically extracted however and used in the development of other toxins.

A gas mask is provided in the mod to help reduce the effects of the toxic gas (effected by toxic sensitivity).


Tangleroot is an aggressive genetically modified vine. It has very sharp thorns that the plant can use to grapple and constrict targets that wander into its path, which in itself can be a laboured exercise. It also gives off a gaseous vapour. The alkaloids the plant uses are toxic and can be debilitating; effect consciousness and manipulation. With severe exposure the toxin has a chance to infect the target host with an illness akin to muscle parasites. There is also a chance for chemical damage in the brain. The toxin can ultimately be lethal.

The Tangleroot thorns can be harvested and used to create concentrated versions of the plant toxin. They can also be used to provide an anti-toxin in the form of Tangleroot Juice when mixed with Neutroamine.

When fully mature Tangleroot can "creep" and will sporadically invade neighbouring cells.

Tangleroot toxins do not effect insects or mechanoids.



This chemical allows you to produce a layer of foam that specifically attacks blight on plants. It is fast acting, but also depends on how long the blight has been left to take hold on the plant prior to its application. It is made using Chemfuel, Phenol, Neutroamine and Stinkroot leaves.


Plant killer foam will act against all plants except those of a medical nature that seem to offer a natural resilience to the toxins used. Made using Chemfuel, Phenol and Stinkroot leaves.


Tree killer foam is more refined than plant killer and is more selective in targeting trees and plants that are considered as weeds (Miscellaneous plant category). It is a bit more effective that plant killer and is made from Chemfuel, Phenol, Stinkroot leaves and uses Wood as an additional ingredient to provide genetic selection.


Weed killer is even more selective than it tree killer counterpart, selectively targeting only plants that are considered as weeds. Ingredients include Chemfuel, Phenol, Stinkroot Leaves and Hay (genetic component).


Filth killer foam is a very potent active detergent that can be used to passively clean areas. Made from Chemfuel, Phenol and Herbal Medicine.

(Suggest using mods that can help with cleaning zoning definitions as all the foams this mod applies can still be cleaned themselves if within the designated cleaning zones, though of course the use of the default home zone will still help here).


Insect Killer foam is toxic in nature to all "insectoids". It breaks down their epidermis of chitinous plating exposing intermediate areas and inner fluids which then reacts with the toxin in a combustible; the use of this toxin can be very effective in handling insect scenarios, but best used with caution due to the fires. Made from Chemfuel, Phenol and Insect Jelly (genetic component).


Mind killer is a concentrated liquid that releases a faster acting form of the Stinkroot Gas. It can be weaponised as a mortar shell that can be further used in an IDE trap and also as a grenade. Made from Chemfuel, Phenol and Stinkroot leaves.


Tangle Killer is a concentrated liquid of the Tangleroot plant toxin and it is much more faster acting. This can be weaponised in a mortar shell and IDE trap, also in grenade form. Made from Chemfuel, Phenol and Tangleroot thorns.


Tear Gas can be helpful in diminishing the capability of a victim (especially sight) whilst causing some painful irritation. Associated items are available as trade items, but if you have the social supplements mod loaded then you can utilise chilli peppers to make them.


A liquid foam used to help clear snow over time.



Application of the foam or use of these toxins is handled using multiple delivery methods.

"Sprayer": allows the toxins to be directly applied as foam to small areas with control. (Manual process when drafted). The sprayers also have a limited number of uses (indicators provided).

"Mortar Shells": The foams and gases can be delivered with shells using mortars.

"IDEs": The shells can be used for IED traps. (Note only Insect Killer, Mind Killer, Tangle and Tear Gas IDEs are provided as default, the other types require additional mod support.)

"Foam Poppers": Foam poppers can be setup for Blight and Insect foam , trigger is the presence of a hive in the case of insect foam poppers.

"Grenades": Insect Killer, Mind Killer, Tangle Killer and Tear Gas can be weaponised.

Applied foam to a surface will linger for a while and remain active but it will eventually disperse.



Vary base research costs by a percentage level.

The mod includes settings to tweak which plant gases are used and whether a maximum radius at full maturity. Provided in case anyone experiences any graphical performance issues with their hardware. There's also a toggle for Tangleroot creep.

The relative toxicity setting allows you to tweak how effective the various toxins and other active chemicals perform in relation to default values (percentage).



Apothecary - Allows the ability to make ammonia liquid fertiliser and plant sprayer applicator.
Remote Tech - Some of the IDEs become available for use when this mod is loaded.
RimPlas - Sprayers will use RimPlas instead of Steel in their ingredients.
Seeds Please Adds patch support to generate seeds for plants used in this mod.

Muliplayer support (beta).

(Includes custom harmony C# override process to apply only this mods filth to any fertile terrain).


Multiple research projects in own tab with bulk recipes as relevant.

Save compatible and mod friendly.

To remove the mod you would have to remove all items introduced first and would expect some initial harmless error messages on removal that will subside with further saves.
