Bethesda has delayed the release of downloadable content packs for the PlayStation 3 version of Fallout 3.

Back in May Bethesda announced plans to bring Fallout 3 DLC packs Operation: Anchorage, The Pitt and Broken Steel – each featuring between four and six hours of additional content - to Sony's platform. With the DLC already available for PC and Xbox 360, Operation: Anchorage was due to hit the PlayStation Network in June and be followed by the latter two packs "4-6 weeks apart."

Acknowledging the developer’s failure to deliver the first of the planned DLC packs last month, Bethesda production director Ashley Cheng outlined a new release timeframe in a post on the PlayStation Blog.

“Unfortunately, the content is going to be releasing later than originally expected. Our DLC expands on the original game tremendously… and is no trivial undertaking. We are knee deep in testing at the moment, and we’re hoping to have the first DLC out by the end of September.

“We have decided that Broken Steel will be the first release since it is easily the most requested DLC from our fans. After Broken Steel, we’ll be releasing Operation: Anchorage and The Pitt shortly thereafter, probably at the same time – just to get them out to you as soon as we can.

“After that we’ll have Point Lookout and Mothership Zeta available as soon as we can, so that the wait between DLC is as short as possible.”
