According to a post with cracked code information
on IncGamers, the new code replacing the 11-12-13 code read: “Nuclear winter is coming. Reserve your future home today! Call 877-260-2299.”
The phone number played the Tranquility Lane theme from Fallout 3, and contained more Morse code, but the number apparently no longer works as of today.
The Vault-tek logo is also showing on the site, and new portions of the website show “VT137-7042299-V119BST: PERMISSION DENIED BY OVERSEER.”
