Throwing it out but, Eternal Bloodlines had the wrapped exterior but as soon as you entered the building you got an immensely impressive starting facade on the inside.
The new Sprungs, atleast for IPs, seem to borrow on a similar logic to how Hollywood had it for SS747 and SS22, where they couldn’t *really do much* for the external IPs, atleast for outside the building. I imagine this is what Orlando had to figure out on immediately what’d be the start of the house.
Additionally it’s not like we won’t see the vault door, probably means they’re gonna save it as a big moment for once you get past the Massacre.
