Fallout 3 Game of the Year Edition will arrive on October 13, Bethesda today announced along with news that its DLC will hit the PlayStation 3 thick and fast from September 24.

The GotY edition of Bethesda's post-apocalyptic RPG includes all five batches of its downloadable content and will be priced at $50 on PC and $60 on Xbox 360 and PlayStation 3--50 and 60 Euros respectively in Europe.

PlayStation 3 DLC--originally scheduled for late June--will finally begin arriving from September 24 when Broken Steel is released, which crucially continues the game beyond its original ending. October 1 will see the release of 'Operation: Anchorage' and 'The Pitt' packs, while 'Point Lookout' and 'Mothership Zeta' will arrive on October 8.

Bethesda paved the way for the PS3 DLC with an update which "addresses a number of issues, includes some optimizations, and adds trophy support for the DLC."

Those that have purchased all five Fallout 3 expansions for Xbox 360 by September 22 will receive a free "premium theme," developer Bethesda and Microsoft revealed today.

The post-apocalyptic makeover of the Xbox 360's dashbord will be available October 1, with Microsoft sending out the free download tokens to those that qualify. Bethesda stipulated that the free theme offer is only good for those that bought the "English" versions of the add-ons.

"This is something we've been asked about a lot and we're happy to finally be able to bring it to fans as a small token of our appreciation," said Fallout 3 director Todd Howard. The theme will also be released separately for 240 MS Points ($3).

Fallout 3 developer and Fallout property owner Bethesda has filed a lawsuit against former owner Interplay to clarify that Interplay no longer holds any rights to the franchise.

Bethesda, which purchased the post-apocalyptic property from Interplay for $5.75 million, says Interplay never sought the necessary approval to re-release the original Fallout games at retail or via digital distribution, and no longer holds the Fallout MMO license.

Bethesda further claims that Interplay's unapproved re-releases of Fallout, Fallout 2 and Fallout Tactics: Brotherhood of Steel though the "Fallout Trilogy," "Fallout Collection" and "Saga Fallout" bundles are "confusingly similar to Fallout 3... Read more

Developer Bethesda has confirmed that Mothership Zeta, the fifth downloadable expansion for its action-RPG Fallout 3, "is the last DLC we have planned."

Following a report from MTV Multiplayer, which noticed that Bethesda had referred to the add-on as the game's "final DLC," the studio told Joystiq that there are no plans for additional content, though it also cautioned that one should "never say 'never.'"

Released on PC and Xbox 360 today, Mothership Zeta is now available for 800 Microsoft Points ($10). The five downloadable add-ons are also headed to PlayStation 3, with the first batch due around September. Meanwhile, an enhanced "Game of the Year" edition of Fallout 3 hits retailers in October, bundling all of the DLC with the game itself.

Oooohheeeeoooh. Bethesda's latest DLC pack is threatening to abduct your Microsoft Points. If you want to believe, trust no one, watch the trailer below, and prepare to fight the future.

Mothership Zeta is coming to PC and Xbox 360 this Monday, August 3, for 800 MS Points ($10). The PlayStation 3 version will arrive sometime later on.

Gearing up for the impending release of "Mothership Zeta" for PC and Xbox 360, developer Bethesda has issued a few new screenshots from the latest Fallout 3 add-on.

Priced at 800 Microsoft Points ($10), Zeta--the last of the announced downloadable expansions for Fallout 3--hits PC and Xbox 360 on Monday, August 3, delivering a new space-themed quest, weapons and such.

A PlayStation 3 edition of the DLC is due later on, with all of the DLC released thus far coming to retailers in October through a Game of the Year edition of Fallout 3.

Mothership Zeta, the last of the five announced downloadable expansions for Fallout 3, will debut on Monday, August 3, developer Bethesda announced today.

Priced at 800 Microsoft Points ($10), the add-on will be available for PC and Xbox 360 players that day, with PlayStation 3 owners of the action-RPG getting it a bit later on. Originally, Mothership Zeta was slated to arrive in late July, marking a slight delay.

Along with the above screenshots, Bethesda issued a fact sheet detailing the new items, locations and story elements to be found in the expansion. Remember, all five bits of Fallout 3 DLC will be bundled alongside the original adventure in a... Read more

Having missed its initial late June estimate, developer Bethesda now expects the first batch of Fallout 3 downloadable content to hit PlayStation 3 "by the end of September."

"Keep in mind that not only do we need to test each DLC on PS3, we also need to test each DLC when used in conjunction with each of the other DLC, as well as all of them together, along with the entire original game," producer Ashley Cheng explained.

Whereas Bethesda originally planned to release the five packs roughly "4-6 weeks apart," it's now aiming to get them up "as soon as we can." Based on requests, "Broken Steel"--the only one to further the main story and raise the level cap--will... Read more

As Independence Day is drawing near, online retailers have already kicked off their weekend sales, with the highlight thus far being Steam's half-off sale on Fallout 3.

Usually $50, a digital download of Bethesda's acclaimed post-apocalyptic PC RPG can temporarily be yours for $25. However, this doesn't include any of the $10 downloadable expansions, so the more frugal of you may want to wait until October, when the game and its five downloadable add-ons will be sold together in a $50 Game of the Year bundle.

Other standout deals include the X-Com Complete Pack for $7.50 at GamersGate and Call of Duty: World at War PC for $35 at Direct2Drive. Impulse also has several noteworthy sales going on, including a $30 Sins of the Solar Empire/Expansion Bundle and free copies of Red Faction 1 and 2 with a pre-order of RF: Guerrilla.

Oh, and don't forget that with Street Fighter IV PC coming out next week, both Steam and Impulse are offering 10% off pre-orders, making the fighting game $36.

Fallout 3's swamp-bound 'Point Lookout' downloadable content has been released, with the PC edition receiving a new patch to support the accompanying new achievements.

Fallout 3 patch 1.6 is now available on FileShack in US, UK and German flavours, each weighing in at 50MB and bringing no changes beyond the achievements.

Point Lookout adds an open area of Maryland swamp with new quests, enemies and weapons. PC and Xbox 360 post-apocalypteers can venture into Point Lookout today for 800 Microsoft Points ($10), while PlayStation 3 players have a wait of several months.

Bethesda has released new screenshots of upcoming Fallout 3 downloadable content Point Lookout, showing the answer to most problems in the swamp: a hefty axe.

During E3 we had a gander at the delights Point Lookout brings to Fallout 3, including a new open environment, several fresh weapons, and a sinister plot by mutated cultists.

A new developer diary from Point Lookout's lead designer and lead artist details the swampland's aesthetic development and gameplay design challenges the area raised.

Point Lookout arrives June 23 on PC and Xbox 360, priced at 800 Microsoft Points ($10). A PlayStation 3 release is expected once the previous three DLCs have hit the console.

As the ferry docks in the decrepit amusement park, complete with the ruins of ferris wheel poking above the rows of run-down and long-shuttered booths, I find myself already facing one of those tricky moral conundrums Fallout 3 is known for. Do I explore this fascinating post-apocalyptic wonderland, or head off to that mansion on the hill?

Fortunately, in this instance, it really doesn't matter. At roughly one-fifth the size of Fallout 3's initial game world, the entirety of the new landmass that the June 23-due Point Lookout DLC adds to Bethesda's action-RPG is open from the start, enabling you to ignore that quest about the ghoul in the mansion and just explore the wetland.

That lighthouse out in the distance? That cathedral on the hilltop, ever-so-slightly obscured by the murky haze that permeates the swampy area? Go for it... Read more

This murky trailer and several screenshots and give the first peek at Point Lookout, the latest Fallout 3 downloadable content pack, set in the swamps of Maryland.

Point Lookout is released June 23 for PC and Xbox 360, then in a retail bundle with previous DLC Broken Steel in August. Point Lookout will come later to the PlayStation 3, which Bethesda recently announced will receive all of the Fallout 3 DLC.

Two more downloadable expansions for Fallout 3 will arrive over the summer, developer Bethesda announced today, along with word that, beginning in late June, the PlayStation 3 will start to receive all of the Fallout 3 downloadable DLC announced thus far.

"Operation: Anchorage will be released for PS3 in late June, followed by the release of The Pitt and Broken Steel 4-6 weeks apart," said Bethesda. "Release dates will be forthcoming." Previously, that DLC was exclusive to the PC and Xbox 360.

As for the two new downloadable episodes, here's what we know:

• Point Lookout (Late June for PC and Xbox 360 - 800 MS Points / $10)
  Explore a massive new swampland area filled with new quests and content.
• Mothership Zeta (Late July for PC and Xbox 360 - 800 MS Points... Read more

Following a shaky release that saw the Fallout 3 Broken Steel DLC pulled from the PC Games for Windows Live Marketplace, the content has now been restored and is again available for purchase.

The issue was rooted in "a games for Windows Live DRM Install error," according to Fallout 3 developer Bethesda.

The 800 Microsoft Point ($10) add-on extends the end of the original title, opening up new quests and allowing for ten more levels of character progression.

Update: Broken Steel's PC installation issues are "a games for Windows Live DRM Install error", a Bethesda representative has told Shacknews. "Microsoft is working on fixing it, and we'll let everyone know once we've verified it."

Regarding the Xbox 360 achievement anomalies, "The Xbox Live servers don't seem to be fully synched yet with the additional achievements," Bethesda explains. "This should fix itself automatically soon. People won't lose any achievements."

Original: The third Fallout 3 downloadable content pack 'Broken Steel' has been released for the Xbox 360 and PC, and many PC gamers are finding it is, well, broken.

The Bethesda forums bear reports from a number of PC users that Broken Steel fails to install, giving the error message "Not a cryptographic message or the cryptographic message is not formatted correctly. (Exception from HRESULT: 0x8009200D)."

For now, Broken Steel has been pulled from the Games for Windows... Read more

With the last announced Fallout 3 DLC pack, Broken Steel, hitting Xbox 360 and PC tomorrow, developer Bethesda has issued a trailer for the 800 MS Point ($10) add-on.

Be warned that, as Broken Steel picks up where Fallout 3's ending left off, this video spoils some end-game elements for those that haven't beat the post-apocalyptic RPG.

Retailer listings have suggested the existence of an unannounced Fallout 3 downloadable content pack named either "Point Look" or "Point Lookout."

Online retailers eStarland and Deep Discount list a pack containing upcoming DLC Broken Steel and the unnanounced other, joining recent listings for a retail bundle of earlier downloadable expansions Operation Anchorage and The Pitt.

"We have said there will be three DLCs for Fallout 3, for PC and 360," Bethesda marketing VP Pete Hines told Shacknews. "Beyond that we have no announced plans for additional DLC." The third DLC pack, Broken Steel, arrives next Tuesday.

"Announced" is key, as Fallout 3 lead designer Emil Pagliarulo said the company was "working on lots of DLC" during a Games Developers Conference panel in March.

Look at that robot there. That is one hell of a robot. Iron Giant-esque, wouldn't you say?

It goes without saying that Broken Steel, the last foreseeable DLC pack for Fallout 3, is looking like a must-buy for fans. For more on the content, check out our recent preview. It hits the PC and Xbox 360 on May 5 for the price of 800 Microsoft Points ($10).
