You push left on the d-pad to bring up the menu for building stuff and then it's under demolition

[Thatderpykv2guy]

thanks for the help and do metal flours stop them from tunneling or is it just decoration

[D11_Nat]

Nope doesn't stop them! They're persistent fellas. Floors coverings affect walking speed and aesthetics. Walls give a digging speed penalty, with perimeter walls slowing them down the most. Pipes give a speed boost. I feel like water terrain can't be tunnelled under but I'd have to double check!

I have a single water tile all around my prison perimeter and so far it seems no they cannot (at least not yet). Water is listed as impassable though which also means by you and wires emt ect so there are some drawbacks.

Agreed but the trick for wires and pipes under the water is to lay the pipes/wires first and wait for them to finish being built THEN add the water tiles.
