BioWare's community liaison Chris Priestly has told fans that the Lair of the Shadowbroker add-on for Mass Effect 2 has been fixed.
"People using Xbox Live for the Xbox 360 can download and play Lair of the Shadowbroker. If you are an Xbox 360 user, please go ahead and enjoy the new DLC," Priestly posted on the BioWare forum.
"Lair of the Shadowbroker should now be fixed for the PC and should be able to be downloaded now for both the PC and Xbox 360.
"Thanks to everyone for their patience and help as we fixed this issue."
PC users had reported downloading gigabytes of zeros instead of a working Lair of the Shadowbroker file.
Lair of the Shadowbroker is based around Liara T'soni, squad member from Mass Effect 1, who's intent on rescuing a man the mysterious Shadowbroker has captured.
The conent costs 800 Microsoft/BioWare Points.
Eurogamer's Lair of the Shadowbroker review will be published this afternoon.
