Valve has celebrated the release of the Skyrim Creation Kit by releasing Fall of the Space Core, Vol. 1. The Skyrim mod places the Space Core from Portal 2 into the game, following you around as you explore.
Excitingly, the little guy is voiced by none other than video game voice actor legend, Nolan "Nathan Drake" North.
"Since Skyrim was the only major release of 2011 without Nolan North in it, you should consider this mod a patch to fix that problem," reads the mod information. "You can now feel free to include Skyrim in the 'Nolan North' section of your video game library, which is to say, your video game library."
