The Secret World’s next update, Issue #2: Digging Deeper, will be arriving a day later than initially planned following the first delay of the update. Senior Community Manager Oliver 'Tarib' Kunz made the announcement today on The Secret World forums that the update which was scheduled to deploy tomorrow, will be delayed until Wednesday, September 12th to allow for further testing to ensure a smooth launch.

Issue #2: Digging Deeper is just around the corner and we have been working on adding the final coat of paint during the past few days in preparation for launch. To ensure that everything works as intended and is ready for the live servers, we decided to run a few extra tests to avoid any possible last minute issues. This means that “Digging Deeper” will be ready one day later than planned and will be deployed to The Secret World live servers on September 12th. Pending the mentioned tests, we will announce the update downtime on the usual channels as soon as all details are available.
