The general-purpose antibiotic. Each pill runs a five-minute antibiotic course that kills the bacteria behind colds, flu, pneumonia and cholera.
Effects
Antibiotics 5 min12 pillsTimer resets on re-dose
How to use
Take one pill and wait. If symptoms return once the five minutes are up, take another. A new pill restarts the timer rather than stacking.
Survivor advice
It does nothing for salmonella or food poisoning, and a stage I wound infection keeps growing through it. Clean the wound with disinfectant first.
Activated charcoal that binds salmonella in the gut. It works slowly: nothing happens for the first 200 seconds, then it clears the infection.
Effects
Delay ~3 min 20 sThen clears salmonella for 100 s12 tablets
How to use
Take one tablet and let it work. Taking another while one is active does nothing, so don't waste them.
Survivor advice
One tablet removes about as much salmonella as your body can hold, so a single dose is usually enough. Keep drinking, because the vomiting costs a lot of water.
Mild painkiller. It takes the edge off pain and shock effects for four minutes. It doesn't heal anything.
Effects

Effects
Chelation 5 min20 tablets
How to use
Take one tablet per five-minute course and repeat until the shivering stops.

How to use
Use it on a filled canteen or bottle, not on yourself.

Survivor advice
Test the donor's blood type first, then write the type down so you know who it can go to.
A full bag of donated blood. It still needs an IV Start Kit before you can use it.
Effects

Effects
Needs a batteryStops a heart attackCauses one in a healthy heart
How to use
Fit a battery, wait for it to charge, then use it on the patient.
Survivor advice

Medical storage
How to use
Put pills, bandages and injectors inside.
Survivor advice
A good standard kit: bandage, disinfectant, tetracycline, charcoal and codeine.
An emergency injector that floods your blood with oxygen. For 30 seconds you can survive Lantia's atmosphere without a suit, but it wears your body down while it lasts.
Effects
Breathable for 30 s-0.4 health/s-3.5 shock/sNamalsk only
How to use
Inject it just before you step into Lantia's air or when your suit fails. Another shot restarts the 30 seconds.
Survivor advice
Use it to get to cover or a suit. Chaining shots drains health and shock fast enough to knock you out.

Effects
AI ignores youUp to 45 minShorter at low healthNamalsk only

Survivor advice
Keep spare O2 tanks and batteries. If the suit loses pressure on Lantia, inject Hyper Oxygenated Blood straight away.
Critical
Each wound drains up to 20 ml of blood per second (serious wounds bleed at full rate, lighter ones at 60% or 10%). A normal wound closes by itself after about five minutes, but you usually don't have that long.
Symptoms
- Blood drops on screen
- Blood level falling
- Visible wounds
Cause
Gunshots, melee hits, infected attacks, falls and broken glass.
Cure
Survivor advice
Bandage straight away, then deal with infection. Use a sterile bandage or disinfect first, because dirty dressings cause wound infections.
Critical
A broken leg slows you right down. The bone heals itself, but slowly: about a fifth of normal speed once splinted.
Symptoms
- Limping
- Cannot sprint
- Pain effects
- Bone icon
Cause
Falls from height, vehicle crashes and heavy hits to the legs.
Cure
Survivor advice
Splint first, then painkillers so you can move. Stay fed and hydrated, because healing needs good blood, water and energy levels.
Serious
A broken arm makes your aim sway and every action takes longer. It heals over time once stabilised.
Symptoms
- Shaky aim
- Slower actions
- Pain effects
Cause
Falls, melee blows and gunshots to the arms.
Cure
Survivor advice
Your aim sways badly, so avoid hunting at range until the arm has healed.
Critical
You have 5,000 ml of blood. The screen greys out below 4,000, shock damage starts at 3,000 and you die at 2,500. Blood comes back at about 0.3 ml per second when you are well fed and hydrated.
Symptoms
- Screen losing colour
- Dizziness
- Passing out
Cause
Untreated bleeding, blood donation and hemolytic reactions.
Cure
Survivor advice
Eat and drink to speed up natural recovery. Saline is the safe quick fix. Blood transfusions are faster but the type must match.
Critical
Shock builds up with damage. Once it drops below 25 you pass out. It recovers quickly while you're awake, but much more slowly when you're unconscious or low on blood.
Symptoms
- Blurred, tunnelled vision
- Screen going dark
- Unconsciousness
Cause
Heavy hits, gunshots, low blood and the PO-X antidote.
Cure
Survivor advice
Fix blood loss first. At critically low blood, shock keeps building until you get a transfusion.
Critical
You collapse and can't move until your shock recovers. Blood recovers twice as fast while you're out, but you're an easy target.
Symptoms
- Black screen
- Heartbeat audio
- Cannot act
Cause
Shock falling below 25.
Cure
Survivor advice
Teammates should bandage and transfuse you. If you pass out in water you drown after 20 seconds.
Critical
Your body attacks the wrong blood. You lose 7 ml per second until 500 ml is gone.
Symptoms
- Rapid blood loss after transfusion
- Shock
Cause
Receiving blood of an incompatible type.
Cure
Survivor advice
Prevent it by testing blood types first. If it happens, an IV Saline Bag makes up the loss.
Critical
Health drains at 0.2 per second and shock at 2 per second until someone shocks the heart back into rhythm.
Symptoms
- Health and shock dropping
- Collapse
Cause
Being shocked with a defibrillator when the heart was fine.
Cure
Survivor advice
Only defibrillate a patient who actually needs it.
Serious
Body temperature above 38.5 °C. It is a symptom of something else and drains water while it lasts.
Symptoms
- Feeling hot
- Blurred vision
- Faster dehydration
Cause
Influenza, cholera or a stage II wound infection.
Cure
Survivor advice
Treat the underlying disease and keep drinking.
Serious
Staying cold burns through your energy and weakens your immune system, which makes colds and flu much more likely.
Symptoms
- Blue temperature icon
- Shivering
- Faster hunger
Cause
Wet clothes, wind, night, snow and being underdressed.
Cure
Survivor advice
Dry off by a fire, wear insulated layers and eat. Take vitamins after a long spell in the cold.
Minor
Too much heat makes you lose water quickly.
Symptoms
- Red temperature icon
- Sweating
- Faster thirst
Cause
Too many layers, sprinting in heavy gear, standing by fire.
Cure
No item cures this directly. See the advice below.
Survivor advice
Take off a layer, walk instead of sprinting and drink.
Minor
Wet clothes insulate badly and make you cold much faster.
Symptoms
- Wet status
- Getting cold fast
Cause
Rain, swimming and wading.
Cure
No item cures this directly. See the advice below.
Survivor advice
Dry off by a fire or put on dry clothes. Wear waterproof outer layers.
Minor
An overfull stomach makes you vomit, and you lose the food and water you just took in.
Symptoms
- Stuffed icon
- Vomiting when overfull
Cause
Eating or drinking too much in a short time.
Cure
No item cures this directly. See the advice below.
Survivor advice
Eat in smaller portions and wait between meals.
Critical
Each exposed body part builds up its own frostbite timer, and the colder you are the faster it fills. When a timer fills, that zone gets frostbite and your maximum health drops. Feet, hands and face each take 20% of your remaining health cap, head 14%, and torso and legs 8% each. Frostbite never heals. It stays until you die.
Symptoms
- Frostbite zone icons on feet, hands, face, head, torso or legs
- Maximum health permanently lowered
- Health stops regenerating past the cap
Cause
Staying cold (light-blue temperature or worse) with a body part uncovered, or covered by clothing that is ruined or at least 25% wet.
Cure
Survivor advice
Prevention is the only answer. Wear dry, undamaged boots, gloves, a face mask, a hat, a jacket and trousers. Covering a zone in time lets its timer wind back down before frostbite sets in. The LEHS suit makes you immune.
Critical
Once you are critically cold, Namalsk drains health directly: from 0.02 per second, rising to 0.22 per second as you get close to freezing solid. Your energy drains at the same time.
Symptoms
- Dark-blue temperature icon
- Rapid energy loss
- Constant health loss
Cause
Staying in the dark-blue (critical) cold zone. Namalsk makes this hurt far more than vanilla does.
Cure
Survivor advice
Light a fire, get indoors and change out of wet clothes. Freezing and frostbite usually hit together, so warm up before your gear fails.
Serious
The air temperature drops by a further 4–7 °C for roughly 15–22 minutes, including a 100-second fade in and out. Gear that kept you warm a minute ago might not be enough.
Symptoms
- Sudden temperature drop
- Frost screen effect
- Overcast sky
Cause
A random Namalsk weather event that needs some cloud cover.
Cure
No item cures this directly. See the advice below.
Survivor advice
Get to shelter and a fire as soon as the frost appears. It is the worst time to be wet or missing gloves.
Critical
Lantia's air can't be breathed. Unprotected, you lose 6.25 health and 12 shock every second, which kills you in well under 20 seconds.
Symptoms
- Muffled hearing
- Hit effects
- Health and shock collapsing
Cause
Being on Lantia outside the safe zone without a pressurised LEHS suit or Hyper Oxygenated Blood.
Cure
Survivor advice
Never cross without a suited-up LEHS or an oxygen shot ready. The safe zone at the arrival point is the only place you can breathe.
Serious
For 30 seconds after the shot you lose 0.4 health and 3.5 shock per second. That is the price of being able to breathe on Lantia.
Symptoms
- Holding breath, then exhausted breathing
- Health and shock draining
Cause
The side effect of injecting Hyper Oxygenated Blood.
Cure
No item cures this directly. See the advice below.
Survivor advice
Make sure your shock is high before injecting. Two shots back to back can knock you out.
Critical
The zone adds about 5 chemical agents per second through any unprotected slot, which leads to the vanilla chemical poisoning stages. Gas mask filters wear out quickly inside.
Symptoms
- Coughing every few seconds
- Chemical poisoning building up
Cause
Entering a Namalsk contaminated area without full chemical protection.
Cure
Survivor advice
Wear a gas mask with a fresh filter and full NBC gear. Carry spare filters, and inject PO-X once you are out.
Critical
Worse than a normal toxic zone. As well as poisoning you through the air, it opens contaminated wounds on unprotected body parts, and every open wound feeds more poison into your blood.
Symptoms
- Coughing
- Contaminated bleeding wounds
- Chemical poisoning building up
Cause
Entering the Phoenix rig's toxic area with any unprotected body part.
Cure
Survivor advice
Full NBC protection on every slot is essential. Bandage straight away when you leave, then use PO-X.
Minor
A beneficial effect. AI won't target you for up to 45 minutes, scaled down by your health when you inject (to a minimum of a quarter).
Symptoms
Cause
Injecting the VEGA.n7-PAN Enzyme.
Cure
Survivor advice
It only fools the AI. Animals and the environment will still hurt you, so don't get careless.
Minor
The first stage of an influenza infection. Mild, but left alone it can turn into flu and then pneumonia.
Symptoms
- Sneezing (attracts nearby infected)
Cause
Being cold or wet with a weak immune system, or catching it from a sick player.
Cure
Survivor advice
Warm up, eat and take vitamins or tetracycline. Once it clears you are immune for 15 minutes.
Serious
A cold that has taken hold. Frequent coughing draws in infected, and the fever dehydrates you.
Symptoms
- Coughing
- Fever
- Faster dehydration
Cause
An untreated cold that keeps getting worse.
Cure
Survivor advice
Take tetracycline right away. Once cured you are immune for 5 minutes.
Critical
The last stage of influenza. It damages your health continuously and ruins your stamina.
Symptoms
- Heavy breathing
- Constant health loss
- Stamina drains faster, recovers at half speed
Cause
Influenza left untreated until the infection is almost at its peak.
Cure
Survivor advice
Take tetracycline and keep taking it. This one kills.
Critical
A waterborne infection that drains water constantly, and every time you vomit you lose a lot of water and energy.
Symptoms
- Vomiting
- Severe dehydration
- Fever
Cause
Drinking untreated water from ponds, lakes or rivers.
Cure
Survivor advice
Take tetracycline and drink only clean water. Use chlorine tablets or boil water to prevent it.
Serious
Food-borne bacteria. Antibiotics don't work on it. Only charcoal does.
Symptoms
Cause
Raw or rotten food, and eating with bloody or dirty hands.
Cure
Survivor advice
Wash your hands after skinning or bandaging, and cook your meat properly.
Serious
Your body throws out the poison by vomiting until it is gone. No medicine speeds it up.
Symptoms
- Repeated vomiting
- Water and energy loss
Cause
Rotten or burnt food, and drinking disinfectant, gasoline or dirty liquids.
Cure
No item cures this directly. See the advice below.
Survivor advice
Don't eat or drink much until it passes, then rehydrate. Check food condition before eating.
Serious
An early infection. Disinfectant clears it instantly, but antibiotics don't work at this stage.
Symptoms
Cause
Bandaging or stitching with dirty items, or leaving a wound untreated.
Cure
Survivor advice
Disinfect the wound as soon as you feel pain after bandaging. It takes about 20 minutes to reach stage II.
Critical
A serious infection that drains health until it is cured. Antibiotics now work at half strength, and disinfectant still helps.
Symptoms
- Heavy pain
- Fever
- Shaking hands
- Slow health loss
Cause
A stage I infection left untreated.
Cure
Survivor advice
Use both: disinfect the wound and take tetracycline courses until it clears.
Critical
Toxic metals build up in your body. Only chelating tablets remove them.
Symptoms
- Shivering
- Dehydration
- Slow health loss
Cause
Contaminated food and water.
Cure
Survivor advice
Take chelating tablets and drink clean water. Stay away from the source.
Critical
Poison builds up the longer you breathe the gas. Stage III damages you by about 3 health per second and will kill you quickly.
Symptoms
- Stage I: coughing
- Stage II: coughing and vomiting
- Stage III: vomiting, heavy damage, collapse
Cause
Toxic gas zones without a gas mask and protective suit.
Cure
Survivor advice
Wear a gas mask and full NBC gear. Leave the zone, then use the PO-X Antidote.
Critical
A brain disease that makes you laugh uncontrollably and shake your aim. No medicine cures it.
Symptoms
- Uncontrollable laughter
- Shaking and aim sway
Cause
Eating human flesh.
Cure
No item cures this directly. See the advice below.
Survivor advice
Don't eat human meat. The only reliable cure is a fresh spawn.
