According to PCGamesN, reports have been confirmed that PC users across the net have installed disc 2 of Call of Duty: Black Ops 2, and were welcomed with the Mass Effect 2 game instead. We’re not sure how this could of happened, we’re thinking both the giant publishers somehow use the same company to produce the discs and a disc mix-up collision inevitably occurred. so far, it’s a small majority of people experiencing this strange accident.
While the second disc is necessary to complete installation, affected players can enter the serial number on the box into Steam’s product activation window to activate the game. But they’ll have to wait several frustrating hours for the download to finish and do their best to avoid eye contact with their Friends list in the meantime.
