Survey

Read MHC I 1 Reads one cell you are touching. Infected cells stay marked red for good. Clean cells turn green until they get infected. Ready Perforin & granzyme 2 Kills one cell you are touching. The tissue replaces it with a fresh healthy one. Kill three healthy cells and the run ends. Ready Release IFN-γ 3 Boosts MHC I across the whole tissue: every infected cell shows red for one turn, wherever it is. Cannot be used again for 5 turns. Ready

0 ATP collected from the tissue

A cell shows the biohazard mark the turn it is infected, then hides again. That is the virus shutting MHC I down.

Respiratory burst 3 Kills every bacterium within two tiles around you. Does nothing to a virus. Cannot be used again for 5 ticks. Ready Phagocytic reach 2 Engulf one bacterium up to three tiles away. Cannot be used again for 3 ticks. Ready Interferon shield 1 Puts you in an antiviral state for 2 ticks. No virus will target or strike you while it holds. Long cooldown, so open the window when one is closing in. Ready

Tap an adjacent tile to move, or use the arrow keys when you are not typing an answer. Viruses hunt the highest scorer within four tiles and ignore anyone under 50 points. Getting hit by a virus loses you points, but eating a bacterium within two tiles of a virus pays 50% more.
