Home XI Mystery
I haven’t seen any of these myself, I haven’t been in home for a while. Have you seen these symbols or man hole covers in Home?
My guess going off these clues is there will be a underground world of Home that you access via the man hole cover perhaps. Maybe finding these symbols scattered across Home will earn you Home money or items? Or another mini game? Hopefully we will find out soon.
There are many other Home XI videos on YouTube as well.
