If you played Shadow of the Tomb Raider all the way to the end, then you know how it ends. (Obviously.) But as Kotaku reported today, the game shipped with a very different ending, one that referenced a significant character from Core Design's original 1996 Tomb Raider. That ending was changed in a day-one patch, so most players would never see it, or even realize it ever existed.

There are, of course, major spoilers below.
