Community:Fallout 76 Easter Eggs

Alien
In the AVR Medical Center, one can find a Jangles the Moon Monkey doll lying on a stretcher with a toy alien attached to its face on the first floor, reminiscent of a facehugger from the Alien franchise.

Albert Einstein
Inside the doghouse of the Isolated cabin is a mathematical formula written in chalk: $$R_{\mu \nu} – \tfrac{1}{2} R g_{\mu \nu} + \Lambda g_{\mu \nu}  = \frac{8 \pi G} {c^4} T_{\mu \nu}$$. This is an Einstein field equation, first published by Albert Einstein in 1915.

Breaking Bad
Just north of Sugar Grove, there are several partially buried blue barrels with money on top of them and a skeleton nearby in a lab coat. This references the scene from Breaking Bad in which Walter White buries barrels full of money in the desert.

Distant Drums
The memetic "Wilhelm Scream" is briefly heard in a promotional video for Fallout 76.

Doom
A set of wooden blocks in the apartment building with the Nuka-Cola billboard on the east side of Morgantown spells out "BFG," a reference to the weapon first appearing in the Doom franchise, published by Bethesda Softworks since 2010.

The Elder Scrolls V: Skyrim

 * The raid decals used by the raiders are strikingly similar to the Shadow marks used by the Thieves Guild in Skyrim, down to sharing the "loot" and "empty" marks.
 * On a path west of Vault 96, there is a carriage carrying three dead settlers that resembles the intro scene of Skyrim. It is a possible location to wake up at after drinking Nukashine.
 * One question in the Medic Pioneer Scout exam involves a patient that has been shot in the knee. One incorrect answer is to "advise Ricky to give up on adventuring," a reference to the memetic line "I used to be an adventurer like you, then I took an arrow to the knee."

Fallout: New Vegas
One of the raider tribes that previously existed in Appalachia was the Gourmands. This appears to be a reference to the White Glove Society and their restaurant The Gourmand, that previously appeared in New Vegas, given the preference of both groups for eating human flesh.
