DOWNLOADING THE BETA UPDATE ON STEAM
If you’d like to download the 1.6 Beta Update on Steam, you’ll need to follow these steps:
1. Log into Steam
2. Click on Steam in the upper menu
3. Select Settings
4. Under the Account tab, go to the Beta Participation section and select Change.
5. A drop down menu will appear. Select Skyrim Beta.
6. Select OK.
7. Steam will now restart. After Steam restarts, Skyrim will be updated to the Beta version currently available.
If you opt into the Beta, be sure to back up your saved games or simply be careful not to overwrite your existing saves. If you decide to opt out of the beta program, your old saves will still work with the current release of Skyrim on Steam (v 1.5).
If you decide you don’t want to run the Beta anymore, redo steps 1 – 4. At the drop down, select NONE – Opt out of all beta programs. Let Steam restart, and Skyrim will automatically update itself back to the latest released version.
To provide feedback on the beta update, use our beta forum.
There are rumors that it will be something to do with Snow Elves and vampires. It would be cool to be able to reverse the Falmer's situation and change them back into Snow Elves and find out more about the Dwemer in the process. I really don't care about vampires, though.

All I wanted was co-op.
