I just made notice last month of the free 14day gold trial for purchasing Halo 5 digitaly. So I made a point to redeem the offer yesterday and I can’t seem to find the link below as described. Does that offer expire or am I no longer eligible?
You can redeem codes through your Xbox (or your Windows PC if you have one). Either way works. But if my suspicions are correct, some codes like yours may not be supported anymore and therefore useless, a la Halo Nightfall and whatnot.
