Chemical poisoning

Breathing toxic gas without a working gas mask — toxic zones, gas clouds after an artillery strike, gas grenades.

Without a mask

80 s to critical

Poisoned after ~20 s in the gas.

Critical stage

Dead in ~40 s

From full health, unless someone injects you.

Cure

PO-X antidote

Two injections in the critical stage.

Heals by itself

Light stage only

In ~16 min out of the gas.

Chemical poisoning is poison from toxic gas in your body; the game counts it as agents, up to 500. Without a mask you breathe in 5 agents per second, and every chemical burn on bare skin adds more, even with a mask on. Only the lightest stage fades by itself; from 100 agents the poison stays until you treat it.

Stages

How the disease runs in the game, stage by stage: when it starts, what it does, and whether it still heals.

  1. Light exposure

    heals by itself

    1–99 agents (of 500)

    Symptoms

    • Coughing

    One cough when it starts. In the gas you also cough every 3–5 s from the gas itself.

    Out of the gas it fades at 0.1 agents per second — gone within ~16 min, as long as your immune system is above ~15 %.

    PO-X Antidote· Clears it at once.

    Without a mask: ~20 s in the gas.

  2. Poisoned

    only with medicine

    100–399 agents

    Symptoms

    • Coughing
    • Vomiting
    • Coughing or vomiting blood
    • Losing blood without bleeding
    • Sick icon in the status bar

    A cough every 20–40 s that costs 50 blood, and vomiting every ~3–7 min that costs 250 blood and leaves your hands bloody. Sick icon. Together that is ~2.5 blood per second — more than you regenerate.

    Never by itself — from here on the poison stays. PO-X clears it at once; a transfusion of clean blood takes some out.

    Deadly: ~19 min from full blood (the intervals are random).

    PO-X Antidote· 1 injection clears it completely and wakes you up.IV Blood Bag· Clean blood removes 0.25 agents per ml — a 500 ml bag ~125.

    Without a mask: ~1 min more in the gas.

  3. Critical

    only with medicine

    from 400 agents

    Symptoms

    • Coughing or vomiting blood
    • Passing out
    • Losing health without being hurt
    • Sick icon in the status bar

    You vomit, and 4 s later the shock knocks you out; while unconscious you lose 3 health per second.

    Never by itself. One PO-X injection wakes you up and brings you back to the start of the poisoned stage; a second one clears it.

    Deadly: ~40 s from full health.

    PO-X Antidote· 1st injection: awake and back to the poisoned stage; 2nd: cured.

How to get rid of it

Inject the PO-X antidote: it cures the poisoned stage and wakes you up. In the critical stage you need two. A transfusion of clean blood also flushes poison out.

PO-X AntidoteCombat Gas MaskGas Mask Filter

How to avoid it

Go into gas only with a filtered gas mask and the full NBC suit, and leave when the filter runs low.

Good to know

  • Every chemical burn on uncovered skin lets in 0.33 agents per second, even with a gas mask on.
  • Inside a gas zone your mask filter wears down ten times as fast as outside.
  • A poisoned player’s coughs can pass some poison on to you within 3 m.
  • Other medicine, tetracycline included, does nothing here.

Not sure it is this?

The doctor asks what you notice on your character and names the disease and its stage.
