The 800-point ($10) add-on appears to at least be purchasable and playable on the Xbox 360, though it's apparently having some minor issues with achievement points at the moment. After a relatively smooth launch for the first pack, Operation Anchorage, you'll recall that the second add-on, The Pitt, was mad broken on the 360 on the day of its release. After some time and effort, Bethesda managed to get a fully working version posted later that week.
This time around, it's the PC version of the DLC that's got significant issues. Specifically, Broken Steel refuses to install after the download completes, so those of you looking to boost your level cap and continue the main storyline in the PC version of Fallout 3 may want to wait a little bit until these issues are resolved.
Shacknews went straight to Bethesda, who delivered comment on both platforms' issues.
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."
I'm personally really excited about Broken Steel. Since I never had a chance to dig into the game properly when it was released--and given the discontent I've heard with the game's ending and the unfortunate inability to continue questing after the credits rolled--I'm actually glad I waited until now to play Fallout 3. With this last add-on, it seems like Bethesda's made Fallout 3 into the game it ought to have been in the first place.
