Some players who pre-ordered Alien: Isolation are reporting that DLC codes that came with their copies are not not working, developer Creative Assembly is on the case.
The codes are for the pre-order DLC, which are two extra missions. The issue currently seems to be affecting PlayStation 4 copies of the Nostromo Edition and Ripley Edition.
A forum thread has appeared on the official forums and multiple users are reporting the issues. Some are reporting that the Last Survivor DLC code worked while the code for the Crew Expendable DLC didn’t.
The developer took to Twitter to say it’s investigating
@Baztoon101 Is this on a Playstation? We've had a few reports and are looking in to this now. Thanks for your patience!
