COD Ghost 360/one maps

So i've had Ghost from day one for the Xbone and purchased onslaught last week but obviously have missed not playing online with my pals who are still on the 360 so my question is if i buy Ghost on 360 aswell, do i have to pay for the onslaught maps again?
Also. would my rank/prestige just pick up where my Xbone account left off from?

:)

 

£20 xbox credit for £13.99 on eBay

anyone know how much cod ghosts is to buy as a digital download and if the digital download comes with freefall map?
might work out cheaper doing it that way than actually buying the game

 

Digital games increased in price?

Kida grates to see COD Ghosts is only £33 on steam. Cheaper than even the 360 version lol

 

There was an offer with the season pass that if you bought it on 360 you would also get it on xbox one for free.

I did that and get the maps for both versions of the game. I don't know if the offer still exists though.

Without the season pass though you would have to buy the maps separately for both versions of the game.

.

Your rank, stats and loadouts for the multiplayer does transfer between versions of the game as I regularly play both versions. You just need to link your gamertag to your call of duty account.

Single player saves do not transfer.
