The Tomb Raider reboot isn't all about Lara running around in circles and beating on bad guys.
The newer, more vulnerable Lara will also have to survive, so you can apparently expect some edge-of-your-seat survival elements in the gameplay. For a better look at those mechanics, check out the new Guide to Survival video.
This introduces us to Base Camps, which the heroine will utilize to apply skill points and upgrade her skills and equipment. So essentially, after a long day of barely surviving, you can rest up and reflect on what you've learned, thereby making you more effective for the next day's trials and tribulations. It'd be a mistake to put "survival" in the title of this game but it's nice to have something new; an aspect of adventuring that had previously been absent in the franchise.
