You were bitten on the first day of the outbreak. Time is running out to stop yourself from turning. You are alone in the lab, and you have to make the antiviral that saves you, and humanity with you.

Collect samples

Streak samples from your own blood and from whatever you bring back from the field. Flame the loop, then draw the streaks across the plate with your own hand. A clean streak means a colony you can actually read.

Identify the virus

Read the colony under the microscope and work out its traits one by one. A wrong diagnosis does not stop you. It just makes you build the wrong cure.

Develop the cure

Mix reagents at the bench and synthesize your own core molecule, modules and syringes. Every correct diagnosis unlocks a new recipe.

Trial, Error, Victory!

Load your antiviral into the machine and watch the fight play out under the microscope. Every defeat teaches you something, and every victory teaches the virus something. Do not stop until you have the final vaccine.

Stay alive

Do not work hungry or sleepless. Tired hands shake, and a shaking hand means a ruined streak and a missed injection.
