If you enjoy having your games dissected and explained to you in great detail before you take the risk of actually purchasing them, you're going to love this video series from Square Enix. In the "Tomb Raider Guide to Survival," you'll learn about everything from the opening moments of Tomb Raider's story to the systems that will allow you to upgrade items.
There's a lot more, and that's just in this, the first video in the series. It's a bit heavy-handed, but no doubt there are plenty who will be happy to learn more about Tomb Raider.
Oh, and we're relieved to see once again that Lara Croft definitely does not zipline with her bare hands in the Tomb Raider. Sometimes it's the little things.
