Shadow of the Tomb Raider

In order to unlock the achievement, you need to go, at least, for the bronze medal which corresponds to a total score of 250,000 points in one run.

To reach this score, you need to keep the score multiplier on as much as possible and as high as possible by collecting the blue, green shards and the red lanterns on your route:

- Blue shards (100 points x your multiplier) increase the score multiplier by 1 (+1) and they last for about 10secs; they should be collected while running, climbing and juming;

- Green shards (100 points x your multiplier) increase the score multiplier by 1 (+1) but last more than the blue ones (20secs); they should be collected while interacting with the levers, objects, etc;

- Red lanters (300 points x your multiplier) increase the score multiplier by 1 (+1) and will add a further time bonus; they should be shot from the distance when your multiplier is high enough to get the maximum increment and/or when your multiplier is about to be reset;

There are no penalities that make your score decrease but if you accidentally die, your multiplier (not the score) will be reset.

The tomb is quite generous in terms of the number of shards and lanterns you can obtain simply by going through the route to complete the tomb. You can easily get the score of 250,000 before the entrance to the actual tomb enigma (the timed-door you need to open by pushing the 2 levers).
To keep the multiplier up try to choose a path that you are familiar with and try to collect also the shards that are located in adjacent locations and always take a few seconds to look around for red lanterns; they are often located in high spots near the cave's rooftop or behind some walls or just in the void under the level.

In my first run i got a score of 350,000+ (I kept the multiplier up to 45+) before entering the aforementioned door and i completed then the enigma with more calm.

Additional Tip: At the end of the platforming sequence, before entering the chamber where the tomb enigma (instruments) is located, you need to open a door by pushing two adjacent levers. It takes several seconds before the door opens up and you may risk to lose the entire multiplier of the score. To keep it up save the 3 lanters that are located near the door and shoot them during the time of opening of the door and not BEFORE. This way, you will continue with the multiplier and you can also try to get the iron and gold medals.
