The Secret Project Cobalt Vault beneath Nuka World- Fallout 4 Lore

John Caleb Bradberton is the creator of both Nuka Cola and the CEO of the Nuka Cola Corporation. The man behind Nuka World. However despite this, little is known about him. We find mention of him only in passing, even in the deepest parts of the park. However, a quest we are given at the very beginning of the DLC helps us discover more. The quest is Cappy In a Haystack, and is given to us by Sierra Petrovita, a Nuka Cola enthusiast from the capital wasteland in Fallout 3. After collecting all the hidden cappys, we can enter Bradbertons office, and from here, piece together the real purpose of Project Cobalt and LEAP-X, and what happened to John Caleb Bradberton.
