Bethesda is denying additional DLC rumors for the PC and Xbox 360, fueling speculation that the fourth DLC may be released for the PS3 console. This speculation is supported by the fact that Bethesda has only used 350 gamerpoints out of a possible 750, and only fourteen achievements out of a possible thirty, leaving plenty of room for further Fallout 3 growth.eStarland: Fallout 3 Expansion Pack: Broken Steel & Point Look DeepDiscount.com: Fallout 3 Expansion Pack: Broken Steel & Point Lookout (Xbox 360) Shacknews: Retailers List Fourth Fallout 3 Expansion (May 1, 2009)

The first expansion, released at the end of January, is titled Operation: Anchorage. players will take part in a simulated recreation of a battle from the Fallout series' fictional history, in which the United States army has to fight off the Chinese military for control of the city of Anchorage, Alaska. To win the battle, the player has to secure a mountainside and then infiltrate a Chinese military base. Since the battle takes place inside a simulation, players won't have the armor or weapons they have in the main game. There were new abilities, however, and added a number of new achievements.

The second expansion, The Pitt, takes place in the steel district of the wrecked city of Pittsburgh and is due out in March 2009.
