The game will follow the same basic story as the original, so you'll once again be guiding Lara as she's commissioned to retrieve an ancient relic known as a "scion" (no, not the car). As anyone who's played through the original game can tell you, while the gameplay was aces, the story wasn't big on making sense once you started progressing. As a result, Crystal is fleshing out the narrative to offer some clarity on what the heck is going on.
