Perhaps this is a mistake.
Xbox One owners noticed that the Heritage add-on for Hitman 2 can be downloadedand those who did not buy the sequel.
“Heritage” includes all the missions of the first season of Hitman, transferred to the engine of the second part, so after activation, the client is downloaded Hitman 2 – Prologue, and then all five episodes of the original are installed into it.
It is not clear whether this was a mistake, but the official publishing FAQ says that the Legacy Pack on consoles should cost $ 20.
In this case, the usual first season of Hitman at the time of this writing is available in the Game Pass.
