Contrary to some reviews here, I can only say that for me everything has properly and above all work immediately and that. Without any error message Both codes were unhesitatingly accepted and adopted at the first time. Input via wireless controllers directly via the Xbox One (code use). And yes, I had entered both 25-digit code by hand ... and did it even survived! ;) ... Ok, QR codes would have been nice.
As for the issue with the game character Shadow Jago, I can confirm here that they are exclusively intended for the add-on Shadow Jago and not, as stated, to the complete Xbox One game Killer Instinct. The must / can be downloaded for free in addition the store, although amenities in item 2 on the back of Pappschubers:
Day One Xbox Live Gold includes:
12-month Xbox Live Gold membership
The digital Xbox One game Killer Instinct: Round One, with the exclusive character Shadow Jago
Day One special issue of membership card and packaging.
As I said, contrary to the text on the slipcase, the entire game Killer Instinct is not mentioned and the Killer Instinct: Round One sometimes not !?
(Also) on the membership card (aluminum plate) is above the Code, the following text:
Game Killer Instinct: Round One playable on Xbox One, with character of Shadow Jado:
Granted, a bit confusing. I think that the text was once again before the deadline or release date already in the print shop. Such a thing is indeed more often times. If of course does not happen, but it does.
In any case, for me, as already mentioned, everything works perfectly (as it should) and beyond, sees this product for those who put it interesting and / or a point also very chic and fits well with the Day One other articles.
