As announced on the official Dead Island Facebook page, the   Bloodbath Arena DLC will be delayed. Fortunately, developer  has stated they will make it “available as soon as possible.”

Here is the Facebook announcement  below:

We are working hard to make the Bloodbath Arena DLC available as soon as possible. However, due to further polishing of the main game the finalisation of the DLC code has been delayed. We know that many fans are eagerly waiting for it and apologise for any inconvenience. We expect to announce a release update next week.

Bloodbath Arena is set to be the first DLC available for Dead Island and was originally set for late September. Hopefully they get it out for the fans soon.
