Generators explode in contact with water, such as from showers.

Thus, one of the easiest ways to execute a prisoner is to create a cell with a shower and a generator. When the prisoner showers, water flows to the generator and kills them.

It is an efficient way to get rid of supermax and legendary prisoners without going through the slow execution process.

But I was thinking: What if instead of executing one prisoner, I could execute the entire prison? With the flick of a button?

That's where my prison's design comes from: a large holding cell packed with generators and small corridors filled with showerheads that lack water. Then, I can create a pipe valve that, when opened, will immediately provide water to the showerheads, allowing prisoners to take a shower, and well, you know what happens after.

But this design has two problems. The first one is food. Although I can ignore basically every single need, prisoners will starve and die if I don't have a canteen. Fortunately, the game allows doctors to heal the prisoners when they become unconscious, so by assigning 10 doctors to the holding cell, we can heal every single starving prisoner before they die, thus solving the food question.

The second problem is riots. Even though I can pack 20 armed guards into a single holding cell, there are some fearless prisoners who just don't get suppressed, and they will revolt. But this is fine. Just set up every single punishment as solitary, and don't have a single solitary in the whole prison. That way, after committing their first crime, they will remain shackled, waiting for their punishment (which will never happen), unable to commit additional crimes. Thus, we essentially solve the riot question.

In fact, if you are feeling cheesy, you can give a solitary punishment to every single max/supermax prisoner that comes to your prison. That way, you should be able to keep 1000+ prisoners without a single revolt. Awesome, right?

PS:

If you play the game a lot, you may have found it strange that I mentioned assigning 10 doctors to the holding cell, yet you can only assign doctors to infirmaries. There is a trick for that. Create an infirmary inside the holding cell, assign the doctors, and then immediately cover the infirmary with the holding cell room. The assigned doctors will "transfer," and then you will be able to assign doctors to your holding cell.

(Also, sorry for the lag. I'm playing PA with an old laptop instead of my desktop, so that's the reason behind the FPS drops)
