A working phone number for Vault-Tec appears in Fallout 4, offering fans of Bethesda's post-apocalyptic franchise a fun little surprise if they call it.

Once gamers have finished up with Fallout 4's character creation system at the beginning of the game, players may have noticed a Vault-Tec poster hanging in their pre-war home during the title's opening sequence. While the detail is subtle, those Fallout 4 fans who took the time to look a mite closer will have found a customer service phone number listed on the wall hanging that really works when called.

Interestingly enough, the actual digits included in the fictional technology corporation's listing is two numerals longer than a real world phone number, as it reads 1-888-4-VAULT-TEC, but even so, it still leads callers on a silly excursion. As far as what happens on the other end of the line goes, Fallout 4 fans can either give the fake tech firm a ring themselves, or listen to the recording below to find out.

Some fans of Bethesda's post-apocalyptic series may recall that the Vault-Tec number appeared during the E3 2008 trailer for Fallout 3, and it was in working order back then, as well. Many other eagle-eyed fans spotted it at the bottom of the official Fallout 4 website when it finally went live after providing folks with a countdown and tease on Twitter prior to the game's launch. Nevertheless, Bethesda including the phone number in its most recent entry for the series is pretty neat, and an example of the care it takes when keeping up with continuity.

The Vault-Tec phone number is only the latest a line of many secret surprises hidden away in Fallout 4. Just recently, one fan stumbled across an homage to Ridley Scott's sci-fi movie Alien as an Easter egg in the game. As a matter of fact, it turns out that the developers over at Bethesda are fans of all things pop culture, as the studio also made reference to the Boston-based sitcom Cheers by making the series' main set The Bull & Finch Pub a place that players can visit.

Not only did Bethesda make reference to film and television with Easter eggs, but it also paid tribute to video games of yesteryear. The studio included Holotape Game versions of old titles that are playable on Fallout 4's Pip-Boy 3000 Mark IV, such as a text-based RPG adventure called Grognak the Barbarian and the Ruby Ruins, a Donkey Kong remake known as Red Menace, and even a Pitfall! re-skin called Pipfall!

At this stage of the game, fans expect nearly every developer to include Easter eggs in releases, but in the case of Bethesda, it's impressive that the studio goes to such great lengths to appease practically every demographic possible by tucking away so many treats. And even though there have been quite a few found thus far, with Fallout 4 only having been available for a little over a week, there's sure to be more.

Fallout 4 is out now and is available for PC, PlayStation 4, and Xbox One.
