Well, to celebrate the release of Skyrim's new freshly-baked Creation Kit on Valve's Steam, Bethesda and the creators of Portal have joined forces and released an official mod for Skyrim. THis brings Portal 2's Space Core to Skyrim, how exciting!
To celebrate the opening of the Steam Workshop for Skyrim, Valve and Bethesda have teamed up to bring you the Portal 2 Space Core mod, which will let the aggressively space-centric little robot tag along on your adventures in Tamriel.
Also, 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. 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.
This is how you keep your fans happy on both sides of the fence, Valve and Bethesda, FTW.
Fall of the Space Core, Vol. 1.
