Difference with wall types?

[jwaits735]

Is there any difference between the walls? Concrete vs brick, etc. Is it harder for the prisoners to break out if there were a concrete wall? I just want to know the differences between them all.

Thanks!

Perimiter wall can't be built under and I am told it takes prisoners twice as long to tunnel under it. There is no diffrence between the other walls that I am aware of, other than fence being free.

i don't think they can break through walls at all, they just dig under them. so i think the difference between brick and concrete is purely cosmetic. however, since the walls automatically created to surround your Foundations are always Brick Walls, i use Concrete Walls whenever i manually place walls, so i can tell the difference between the free walls that disappear if more Foundation is added, and the permanent walls.

i've no idea what Peremiter Wall is for though. funny how it says $200 but when you place it is says $150. but it doesn't seem to do anything Fence doesn't do, and since Fence is free...
(edit: ah! so that's it .. sounds pretty expensive for just a delay on tunneling...)

It´s nothing your prison cannot afford once it grows and has 2 or more large workshops.
I usually plan beforehand (by leaving place in the arly stages for a perimeter wall in later times) and urually surround a complex of 2 prison houses (with 36 cells) with a perimeter wall (with a 2 tile wide entrance through which I lead power and water ... and which has metal detectors, so every prisoner entering the cell complex is scanned)

well sure, but that doesn't ... i mean, nothing is unaffordable because you can just keep the prison running making infinite money. that's not really the point. one can also sandbox.

The perimeter wall includes paving stones on both sides, so that adds to the cost depending on if the adjacent blocks are paving stone or not.

Fences are free, but they don't slow tunnels at all. So for early prisons they're perfect, but for late-prisons they're awful.

Concrete and Brick are identical in everything other than appearance. They slow tunnels a little bit.

Perimeter Walls slow tunnels a lot. Placing anything but dirt on either side of a perimeter wall before you build it will stop the game from automatically placing the paving stones.

Prisoners can never break walls, ever. They only tunnel under them.

I had a couple of insane prisoners escape, not at the same time. There are no windows. There is no tunnel. They did not leave by the only exit.

Their escape led me to read this thread in search of finding a reason why. Due to the lack of apparent game mechanic I believe they unintentionally glitched through the wall. I am going to build a perimeter fence.
