Shadow of the Tomb Raider

In the Main Menu, select the "Challenge Tombs" tab and then choose "Zipacna's Craving." In the following menu, you can sift through three different modes: Exploration, Score Attack, and Time Attack.

In order to unlock this achievement, you will need to earn any medal in Score Attack. This mode is all about completing the Challenge Tomb (i.e. reaching the stele) all while collecting/shooting wisps of light to increase your score; the quicker you collect these items, the higher your multiplier and score. The medal requirements are as follows:

• Gold: 1,000,000 points
• Silver: 750,000 points
• Bronze: 350,000 points

As mentioned above, the Zipacna's Craving Challenge Tomb isn't too difficult despite it's length. You should be able to net the minimum score requirement without too much trouble or any video assistance. In fact, the wisps of lights along the main path in this Challenge Tomb are plentiful (regardless which path you take) and you should be able to score a comfortable ~350,000 points even if you break your combo meter two or three times. Just make sure to keep an eye in the sky and shoot the red wisps for some big points to your combo.
