Call of Duty: Modern Warfare Operator Edition - Xbox One [Digital Code]

We don’t have great internet... will my son be able to download.. and we he be able to play the game offline?

I bought this as a gift thinking i will get some sort of code card in the mail. What am i supposed to do now?

I bought this as a christmas gift and i’m not a gamer. do i get a dvd or what does digital code mean? i haven’t gotten any code that i know of?
