Does anybody have any idea what is on the new update today? I havent played fallout online in about a week so it could have come out earlier. Just wondering whats on it. Thanks!

There wouldn't have been an update for Fallout 3. The game is almost 4 and a half years old, updates stopped a long time ago.

If you're playing on Steam, perhaps it was just your Steam cloud saves being uploaded?

It says update required right now. And incorrect, they recently patched the glitch as to where you can get inside the bunker in the army depot on december 18th. Its 3MB

The last patch was released on 27th of July, 2009. The last DLC was released August that year. There's been nothing since, and won't be anything.
