Offers up to 6 different chemical agents, Inspired partially by EHA. My first full effort mod that I don't want to do as a le funny mod. You will learn to fear invisible gasses and even the slightest exposure will result in devastating conditions. Care for the exposed will require full attention from the medic. Use these carefully. ***MODIFIES VANILLA DIVING GEAR/MASK/SPRAYER***

Nerve Agents: -Treated with Pralidoxime Chloride. -A mix of speed in lethality and contamination. -Rapid in terms of progression. -Symptoms affect sight, movement, and the general capability to do tasks. -Can be delivered secretly with a disguised red paint can that is silent and unassuming. -Colorless.

Pulmonary Agents: -Exposure first then build up. -Two types of treatment, binding as pre-emptive treatment before symptoms and flushing when the symptoms kick in. -Symptoms are obvious when they appear with periods of oxygen loss and grows more as time passes by. -Can be delivered secretly with a disguised blue paint can that is silent and unassuming. -Slow but lethal. -Colorless.

Blood Agents: -Lethal dosage is given rapidly. -Kills within seconds upon inhalation. -Gas immediately dissipates within an enclosed area. -No treatments, if you survive just stay still and let it pass through your system. -Causes bloodloss, nausea, and convulsions. -Random periods of paralysis. -Colorless.

Blistering Agents: -Deterrent and quickly develops blisters, rashes, and burnt skin. -Contaminates all personnel. -Treated with binding agents with a specialized bandage. -Dark yellow-green mist. -PENDING FIX: External affliction, downright unusable, causes severe lag with AI. Will make a separate affliction and items purely for the purpose of PVP.(Make sure you have absolutely no AI crew)

Lachrymator Agents: -Immobilizes and hampers target's movements and ability to do basic tasks. -Flushed with decontaminant. -Death by minutes of continued exposure. -Bright white mist.

Psychochemical Agents: -Rapidly alters the target's perception. -Brain death at high exposure. -Colorless.

Incapacitating Agents: -Fast acting and long lasting agent used to incapacitate unprotected personnel -Asphyxiation at high exposure -Colorless

TODO: -find a way to make grenades and others with obvious smoke discharge and only when there is smoke discharge.

Other stuff: Added EHA suit compatibility, per Huntermist's request. Enjoy! https://steamcommunity.com/sharedfiles/filedetails/?id=2977226706 Added hazardous reactors compatibility patch, apologies I didn't realize that mod also modified diving suits. https://steamcommunity.com/sharedfiles/filedetails/?id=2985592425

(Gun in thumbnail is part of my other mod) Other comments from me: Idk let me know what you guys want more and I'll try to respond if it is doable. This is a personal project of mine I do for fun so I don't expect this maintained after a long time. Mod compatibility I don't know either, I could do it for the other stuff like 3 minutes if I feel like it but I'll only do it with permission from the mod authors, if you want to do compatibility for this, I give you full permission on my side, just go bother the other mod creator not me. If you see me on the undertow official discord(I mostly go on baro-modding), feel free to talk to me. Thanks to ASkeleton for helping me design the affliction icon of the Lachrymator agent exposure. Now that this mod has reached its completion, I want to thank you all for your interest towards this mod. I don't have anything else to add now. Once again read the bottom part of this mod.

[Use whatever assets and code you want from this mod to create whatever thing you want as well just credit me in the description afterwards.]
