If you bought Call of Duty: Black Ops 2 for PC or Lego Lord of the Rings for Xbox 360, you might want to check your discs real quick. Users have reported some truly bizarre mix-ups for both games which left them with either demo versions or the wrong game entirely.
Game Informer reports users (as well as one of its own writers) have discovered only a demo disc for Lego Lord of The Rings--clearly labeled "NOT FOR SALE"--sitting unexpected and unwanted within some copies of the Xbox 360 version. The issue appears to have only affected certain shipments, but it's worth checking before you leave the store.
In a more surreal switcheroo, GameSpot has compiled user complaints that some retail packages for Call of Duty: Black Ops 2 for PC have all the discs properly labeled--but the second one is actually for Mass Effect 2. Yes, some copies of Activision's next big shooter apparently contain install discs for Electronic Arts' 2010 space opera (a bit more sci-fi than we'd bargained for), leaving users unable to install either.
Those who prefer zombies over husks can still punch the activation code into Steam and download Black Ops 2, which should give them plenty of time to marvel at how this could possibly happen (and how many heads will roll at the distribution center as a result of Activision and EA's reckoning).
Update: Warner Bros. Interactive Entertainment has confirmed that it will be recalling a small number of Lego The Lord of the Rings games that were released on the Xbox 360 to Walmart, Target and Toys 'R' Us in the US with a disc labeling error. These discs include the full game but were incorrectly labeled as demo discs.
