I'm not sure how it works but probably consecutive hours
I have never read on the game that it would come with a 48 hour code, I know it displays the message "Every copy of Call of Duty: Black Ops comes with free multiplayer" or something like that. Mine didn't come with a 48 hour code but why don't you just get a year subscription, you obviously could afford black ops so why not just get the subscription :P?o0Pwnzorz0o
Yea problem is I just spent my savings on the game so I need some time to save up some more.
Ok so I just got abrand new copy of the game today at a Gamestop 40 minutes away from home, and once I got home I tried the game and went to multiplayer where it says that all copies are supposed to come with a 48 hour trial of Xbox Live but my copy only came with the disc and the booklet.
So I'm wondering if it true that every copy comes with this card, in which case I would have one more reason to avoid Gamestop.
And yes I know it's only 2 days but I really want to play this game online and I will not be able to go anytime soon.
