I just bought dying light the following enhanced edition for my friend gifted and it hasn't...

It can take up to 12 hours for them to receive it. If they don't receive it after that, check for the order in your order history at http://account.microsoft.com and it should show the code there and you can give it to him.

Did you purchase Dying Light: The Following (which is just an expansion for Dying Light) or did you actually purchase Dying Light: The Following - Enhanced Edition (which is Dying Light and the Expansion)? It kinda sounds like you have just purchased the
expansion and would still need to purchase the main game.

Have you tried going to the marketplace on your console and searching for Dying Light: The following enhanced edition and downloading it from there ?

Did you only purchase the expansion? The Following is only DLC for the main Dying Light. You can buy Dying Light: The Following Enhanced Edition, which includes the main game and all DLC. Do you already own the base game?

Hello Jeffery,

Is this just Dying Light or is it "The Following"? If it's just The Following, are you sure you also own the base game? The Following is just DLC so you need to also own the base Dying Light game in order to play the DLC (and for it to be visible in My Games
& Apps too).

To illustrate what I mean, this is the full version of The Following that includes both base game and DLC:

And this is just the DLC, which is unplayable unless you also own the base game:

Let us know how you get on.
