"As of now it looks like the file for the English version on Xbox Live was somehow corrupted," marketing VP Pete Hines told Shacknews.

"We are continuing to look into the issues people are experiencing with The Pitt for Xbox 360," he added. "We are currently working with Microsoft to remove the existing file off of Live to prevent any further downloads. Our plan is to replace it with a new file as soon as possible."

Original: Following today's release of the downloadable Fallout 3 expansion "The Pitt" on PC and Xbox 360, reports are popping up of severe issues with the Xbox 360 edition.

"It's completely broken," AuXoIs wrote over on Major Nelson, as noticed by VG247. "There are these box exclamation points all over...It's like not playable after the bridge because it freezes. If you manage to get past the bridge part you're pretty much in glitch city."

Developer Bethesda is looking into the issue, according to a post from a community manager in a thread full of similar complaints on the official Bethesda forums.

However, the issues aren't apparently universal, as some say they've experienced no problems. Forumites suggest re-downloading the file and ensuring that the entire 682MB are acquired, as some claim that they only downloaded some 492MB or so.

Priced at $10, The Pitt is meant to add a new area, quest and items to the action-RPG.
