Bethesda’s The Elder Scrolls and Fallout video game franchises are two of the biggest and best on the planet, offering not only great games to play but stunning fictional worlds to escape to for countless hours of wandering and adventuring.

So what happens when the two worlds collide? In a new video from director Andrew McMurray, Dovahkiin (or Dragonborn) from The Elder Scrolls V: Skyrim meets a human representation of the Vault-Tec mascot from the Fallout universe, known lovingly as Vault Boy. At the time of their meeting it’s clear they’re not being controlled by players who check to see if someone is friendly before attacking. Much blood is shed.

Click on over to the other side to see how the fight goes down, as well as a behind-the-scenes video showing how the impressive visual effects were created.

Another DLC add-on for The Elder Scrolls V: Skyrim has been announced by Bethesda Softworks.

The add-on, titled Dragonborn, will be released on December 4th, and you’ll be able to pick it up for 1200 Microsoft points.

Not much is known about it yet, but as you can see in the trailer, it involves the first dragonborn. It also looks like those dragon mounts that were rumored recently are legit, but no word on the return to Morrowind yet.
