Dead space 2 online pass

I own dead space 2 for the xbox 360 and used the supplied code for the online pass, I am now playing on xbox one but cannot recover the pass, any suggestions please

:)

 

Am I missing much by not getting Dead Space 2 brand new?

So with Dead Space 3 coming out soon I want to revist Dead Space 1 and pick up Dead Space 2 whilst I am at it. I understand Dead Space 2 comes with a online pass though? is it one just for the stupid multiplayer mode they put in? if so I couldn't care less
and will buy pre-owned.

 

I found a fix for getting the online pass in Dead Space 2 on Xbox One backwards compatibility

Alot of Xbox One users who have downloaded Dead Space 2 from the Xbox store have been having trouble getting the Online Pass required for multiplayer. The game prompts you to select an option for online play; a 2 day free trial, purchase an online pass
and download an online pass using a 25 digit code. The option for purchasing an Online Pass is greyed out, and Microsoft doesn't give you a 25 digit code when you download the game, so none of these options work. EA made the Online Pass free a while ago,
but if you select the Dead Space 2 Online pass in the xbox store, it's listed as currently unavailable.

To get the Online Pass, you have to load Dead Space 2, go to the main menu, select "Store," and then go to the box where content for the game is displayed and scroll down to the Online Pass. It should be available to download and
listed as free.
