When having Charon switch from melee combat to ranged weapons, he will make a remark which alludes to the song called ' Happiness Is a Warm Gun' by The Beatles. This is an allusion to the line ' I love the smell of napalm in the morning.' spoken by the character Lieutenant Colonel William 'Bill' Kilgore in the movie Apocalypse Now.

The Vault-Tec Corporation Eye-On-You camera resembles the camera eye for HAL 9000 of the Discovery One from Stanley Kubrick's 1968 movie 2001: A Space Odyssey.

There are three references to the book Nineteen Eighty-Four: A Novel by George Orwell.
