Fallout 4 Cappy in a Haystack Guide

16 August 2026 | 81

Exploring the vibrant amusement park in the Fallout 4 Nuka-World DLC offers players a unique break from the bleak atmosphere of the Commonwealth. Among the various open-world activities scattered throughout the park, the Cappy in a Haystack side quest stands out as one of the most intricate scavenger hunts in the expansion. Successfully navigating this quest requires sharp observation skills and a keen understanding of the park layout.

Starting the Hunt in Nuka-Town

To begin this long scavenger hunt, players need to locate Sierra Petrovita wandering near the Fizztop Grille area in Nuka-Town, USA. Sierra is a familiar face from the Capital Wasteland who tasks the Sole Survivor with uncovering an old corporate marketing puzzle. She provides you with a special pair of Cappy Glasses that are essential for making the hidden murals visible.

It is important to remember that these clues will remain invisible if your character is wearing a full set of Power Armor with the helmet equipped. Once you have the glasses ready, you can find the very first corporate clue hidden right in Nuka-Town on a wall near a red brick bathroom building. Scanning this image grants you the letter G and officially kicks off your tracking journey across the park zones.

Uncovering the Galactic Zone Secrets

The futuristic landscape of the Galactic Zone holds two distinct hidden murals that players must scan to progress their puzzle notebook. The first image can be found tucked away directly behind the massive Starport Nuka control facility. Search carefully along the low concrete wall situated right next to the southern Employees Only gated security entrance to reveal the letter S.

The second clue in this zone forces players to scale the upper walkways near the high Spacewalk attraction entrance. Follow the elevated paths upward and check the northern wall right next to a pair of blue park trash cans. Interacting with this hidden cartoon drawing gives you the letter R and completes the local planetary sweep.

Tracking Through Dry Rock Gulch

The western-themed region of Dry Rock Gulch presents a completely different environmental challenge for tracking down clues. Players should first head toward the small, isolated cemetery grounds located opposite the Giddyup Kid attraction. Inspecting the back side of a prominent tombstone in the graveyard reveals the letter E.

After completing the graveyard sweep, head inside the dark tunnels of the Mad Mulligan's Minecart Coaster ride to find the next image. The mural is painted on the outer wooden wall of a small shack room containing scattered sleeping bags near the waterfall section. Scanning this graphic rewards you with the letter H and brings you much closer to uncovering the ultimate reward.

Accessing Bradberton's Vault

Once all ten hidden cartoon images have been successfully scanned across the entire amusement park, you will have the full password phrase ready. Return to Nuka-Town to input the code, which finally grants access to the secret office suite of John-Caleb Bradberton. Inside this hidden office, players must solve a moral dilemma involving Sierra and the preserved head of the park's founder.

Choosing to support Sierra's wishes rewards you with a unique Nuka-World jumpsuit cosmetic item. Alternatively, shutting down the power grid grants access to the powerful Nuka-Nuke Launcher weapon variant along with rare crafting ammunition recipes. Regardless of your choice, completing this trial represents a massive milestone for dedicated wasteland completionists.
