Pickaxes and the sonic resonator CBM could also break the wall/door, as could Rat mutants with burrowing.
Speaking of the sonic resonator
That isn’t how it works. It actually bashes all the tiles around you 3 times with a bash power of 110. While strong enough to destroy many objects, there exist things like mi-go furinture and walls that will never get destroyed by the sonic resonator, no matter how many times you use it.
