Bug or feature?
Did Ubisoft do this on purpose? Since this approach seems realistic and logical, players wonder if it is a bug at all. The other walls in the game, however, have an indestructible metal boundary in the floor to prevent exactly that. It can therefore be assumed that Ubisoft did not plan this feature in this way.

In the same way, gadgets on the other side can be destroyed in this way. For example, if you destroy Mute's jammer, you can damage the wall with Hibana or Thermite.
