Objective (Very Difficult): Create a virus to infect the virus on the substrate, and leave the plate clean.
Cells allowed: 1 inserted; no Lipocytes, Devorocytes, or Stemocytes
Notes: A non-viral parasite does not count as a solution. Imagine there is a counter for "Infected cells" and it needs to reach a certain number to complete the challenge.

This swimmer is very far from optimized. Two things create difficulties however. In one way or another, you will need to use or tap into modes 2, 3, and/or 4 in order to infect, and the substrate virus infects those modes -- it will infect your virus and put itself in modes 2-4. Second, your disadvantage is that your virus has to die off, and the other virus is trying to stay alive.
Tip: Doing fancy tricks by copying from one mode to a different mode isn't necessary. In fact, I couldn't get that strategy to work.

Hint (in very tiny print): Keratinocytes are allowed.
