There is a small box on top of another box just outside the bottom entrance of the building with RC-XD/Zipline near Core Foundry. If you hit the box with normal melee you can hear a unique(?) sound but nothing happens. If you have melee machiato and punch it, the box shatters.

I haven’t gotten any dialogue or been able to find another box like it on the map. This worked in standard and cursed.

Is this known to be part of an easter egg already I am unaware of?

This is not the Richtofen Barrel but close to it, and has worked with all characters I tried to punch it with.
