Core problem: You got infected. Pills only reset the timer, they do not cure you. Gene Therapy requires two activations on the same player to actually work. Most players die because they burn pills early, use Gene Therapy once and holster it, or stay silent until they collapse and reanimate on the squad.

1Confirm You Are Actually Infected

Hits while below ~50% HP raise infection chance. Lower HP means higher chance. Failed grapples and no-stamina grapples can infect you outright. Rotten "fart cloud" zombies infect more often.

Infection Timeline (rough, from community reports)
Early
Mid
Late
First blur / white lines Coughing + echo Veins = last 30s
Tell the squad as soon as you cough. Console players missing text chat get ordered to pill too late and turn mid-animation. Call it out the moment you hear the first echo.

2Phalanx Pills: Buy Time, Do Not "Cure"

Phalanx Pills 3 doses per bottle
What they do: Reset the infection timer to the start. The virus is still in you. One bottle = 3 doses.

Exact timing players keep repeating:
If veins are already up and you have Gene Therapy in hand: still take a pill first. The cure does not finish fast enough to save you from the turn without a pill bridge.

3Experimental Gene Therapy: The Real Cure (Must Use Twice)

Experimental Gene Therapy Cure + immunity
One kit, two activations, one player. After the second shot you are cured and immune for the rest of this match. You can use it even if you are not infected yet. Immunity does not carry to the next mission.
If you drop the kit after the blood draw, the sample progress resets. Do not drop it. If someone dies after only the first use, another player can still pick the same device up and finish the sequence.

4Key Decisions

SituationWhat to do
Coughing, no veins, no Gene Therapy Keep looting / pushing, but do NOT waste a pill yet. Ask if anyone is holding a spare bottle.
Veins on screen Pill NOW. Then extract or finish the Gene Therapy sequence.
Gene Therapy in inventory, already late-stage Pill first, then start the two-step inject. Do not start the 30s bar at veins with no pill.
Multiple infected, 1-2 bottles total, mission not almost done Share doses, then early extract (red bunker boxes on the map). Empty-handed extract beats a lost Responder.
No pills, no kit, far from extract Call it. Run the nearest early extract. Last resort is self-sacrifice so you do not reanimate on the squad.
Give Gene Therapy to whoever is already infected unless you want to pre-immunize before a nasty fight. One kit = one person.
