Just picked this up pre-owned...for those who do not know the 'Game Of The Year Edition' comes with every additional map and an add-on campaign chapter as downloadable content.
I asked the shop assistant about the extra content with it being pre-owned (as it's provided on a use once only 'scratch card' format) he checked then showed me the UNUSED card believe it or not!!
Upon checking at the till I also discovered that I had £2.50 on my Game Reward Card as well!
So I actually only paid £2.49...! (Thanks SkilledNutsack!) ;-)
BARGAIN OF THE CENTURY! :-)
I know I've kinda fell lucky here but it's worth checking your local GAME Store...well I think it is!
