Well, maybe not so massively affected, but at least some Black Ops II users are experiencing a rather odd problem when attempting to install the game to their Xbox 360 harddrives. According to player reports on the interwebs, some copies of Call of Duty: Black Ops II have actually shipped with one CD of Black Ops II, and one CD of… wait for it… Mass Effect 2.

Call of Duty: Mass Effect 2?

Right. So, it’s unlikely that this is an issue originating with the publisher, since obviously EA published Mass Effect 2 and Activision published Black Ops II, so chances are it’s a manufacturer’s issue.

If you are having this issue, there is a code on the game box that you can use to download the game via Xbox Live. Still, it’s not all bad–it doesn’t seem to be a widespread issue, so chances are your copy won’t be affected. Hopefully. Fingers crossed.

UPDATE: BioWare has just updated the company blog, and it seems they’re as amused as we are:

If you were one of the affected, chances are you thought it was a mistake, but we prefer to think that it was an omen, and when the universe talks, you should listen.

Apparently the first 50 people to send in a picture of themselves next to the screen with the error, with Disc 2 in their hand will receive a code to download the Mass Effect Trilogy PC completely free.
