GameStop is warning customers that Mass Effect 3 Omega DLC is not working for PS3 owners. A local GameStop manager told me that they have received a large number of calls from PS3 owners that their Mass Effect 3 Omega DLC is not working, many stating that Playstation says the codes are invalid.
GameStop isn’t the only one having a problem with the Omega DLC. PS3 owners have complained to Best Buy and Sony that Omega DLC is not working for them either. Although it shows the DLC is available, users have complained that after purchasing it, the DLC does not download and an error message occurs.
We’ll update you with more information about this shortly.
