Some who have purchased a retail copy of the PC version of Call of Duty: Black Ops II have been unable to finish the installation process because the second disk is not actually Black ops 2, but Mass Effect 2.
Responding to the report, Mass Effect developer BioWare has embraced the mistake, offering the first 50 players who can prove that they were affected by the shipping mistake a free PC copy of Mass Effect Trilogy.
"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,"
"If the universe thinks that you should be playing Mass Effect right now, who are we to argue?"
To avail of this, players must take a picture of themselves with their copy of Call of Duty: Black Ops II, and send it to BioWare. More details can be found here.
