This challenge is primarily a sandbox for learning about and playing around with Virocytes. ;)

Suppose you want to infect a species that uses modes which are different than the modes of your virus? For example, you’re trying to infect 11, 12, 13, and you’re using a swimmer virus that uses modes 1, 2, 3. It can't be done. Why not? And how do you infect a species with modes that are different than your virus? ... trate?dl=0

The species on the substrate uses modes 11-15.

Objective: Use modes 1 through 5 to create a virus that transforms the Phagocyte species into Virocyte-spitting swimmers. (Five modes because your swimmers need two Virocytes to infect from one set of modes to another.)

Max cells allowed: 20

Cell types allowed: All except Devorocytes, but you try those together with a virus to see what happens.

Tips and Hints

One of the best things you can do to see how your virus is affecting another species is this: Place some of your Virocytes on top of a cell from the other species. Select that cell, hit Observe, and very quickly hit Freeze. "Load from microscope" in the Genome tab, then check the different modes of that cells' genome. Sometimes the cell won't get infected, but when it does, you can see if your virus having the effect you want or if something is going wrong. ;)

Of course, you can create an 11-15 virus, but I'm guess that being able to simply copy from one mode to another is a very common misunderstanding. It's certainly a misunderstanding that I had for a long time. So, it's good to know how Virocytes actually work. And, you can copy from one mode to a different mode if you understand Virocytes and use two of them properly.

Why can’t you infect an 11, 12, 13 species with a virus that uses modes 1, 2, 3?

Let’s say your virus is this:
mode 1: Virocyte - splits into 2, 3 with adhesion - copies from 1 to 11
mode 2: Phagocyte - splits into 1, 2
mode 3: Flagellocyte

It might seem like you should be able to copy from 1 to 11 in order to replace the other species’ genome with your own. But here’s what will actually happen:

Your mode 1 Virocyte will become the mode 11 cell in the infected species, including your Virocyte’s child settings. Your mode 1 Virocyte splits into 2, 3. Once it’s infected, the other species will have a mode 11 Virocyte that splits into modes 2 and 3 of its own genome. It will also have a mode 12 Phagocyte that splits into modes 1 and 2 of its genome. Your virus didn’t infect modes 1, 2, 3 of the other species: these cells are exactly the same as they were before. If modes 1, 2, 3 in the other species are the default Phagocytes, then modes of 11 and 12 of the infected species are going to be producing a lot of Phagocytes and no swimmers. ;)

To get the other species to begin reproducing your species, you’d have to infect modes 1-3 as well as 11-13. This will make modes 1-3 in the other species identical to yours. Then, when a mode 11 Virocyte splits into modes 2, 3 it will produce your Phagocyte-Flagellocyte swimmer.

To infect from one set of modes to another, you’ll have to use two Virocytes. The easiest way to do this with swimmers is to use five modes. This is why the challenge is to infect five modes using five different modes. As you begin to infect the species, it will produce many of its 1-5 Phagocytes and things will get a bit ugly ;) , because you haven’t infected both sets of modes in all the cells yet. Then your species will infect the 1-5 Phagocytes and will eventually infect all of those cells as well.

If you have a solution to Infection II / III, it shouldn't take much work to complete the challenge. You can also use the handicapping strategy mentioned in Squares VI.

Try things out and see what happens. ;)

Solution (spoiler)

Use one Virocyte to copy from 1-5 to 1-5, and use the second Virocyte to copy from 1-5 to 11-15.

You can create a virus with 2 Virocytes that completes the challenge like this:
mode 1: Virocyte - splits into 2, 3 with adhesion – copy from mode 1 to 1
mode 2: Phagocyte - splits into 4, 5
mode 3: Flagellocyte
mode 4: Virocyte - splits into 5, 3 with adhesion – copy from mode 4 to 14
mode 5: Phagocyte - splits into 1, 2

Ouch!!!! I got a part of the premise wrong on this one. I'll have to update with corrections.
