The second content update for MMO The Secret World has been further delayed so Funcom can fix a "severe exploit", according to a post on the game's forum.

“There was an issue found that could have led to a severe exploit that we want to fix before "Issue #2 - Digging Deeper" is deployed to the live servers,” wrote the game’s community manager.

"Unfortunately, it will take us some more time to make sure the issue is removed and the new version has been thoroughly tested."

The new content is now expected early next week.
