The new OXM features a cover story for Fallout 3. Bethesda Blog notes:
"The April issue of OXM is now making its way to subscribers in the US as we speak. The cover story features a number of new areas and also features a host of new screens from different parts of the game, including new areas, new creatures/NPCs, weapons, etc. We don't want to give away too much info on what's in there, except to say it has the best ending line of any Fallout 3 preview thus far, thanks to a quote from Emil."
