Shadow of the Tomb Raider preview: Hunting in the dark

In the span of 45 minutes I watched Lara Croft: 1) Drown. Which is to say, nearly two years after it leaked for the first time and a month after it leaked for the second time, I've finally played Shadow of the Tomb Raider, the third in the series since the 2013 reboot and apparently the conclusion of Lara Croft's "origin story." It's also apparently the one where she becomes "The Tomb Raider," according to Eidos, but...isn't that what the last two games were about too? As I said, we played about 45 minutes of Shadow of the Tomb Raider ($60 Steam preorder on Square-Enix.com). If I had to guess, the section was lifted from very early in the game--right after a short prologue, perhaps?
