Before I inform you about the story, I have to bring to your attention some information about Tomb Raider 5 Engine . 
Unfortunately, I have encountered some technical problems, especially regarding the dynamic light, so there are no flares and I was forced to adjust the level.

Dynamic light is for example flares, fire and light when shot.

STORY

Lara Croft recently saw the movie Indiana Jones and the Last Crusade. 
She was intrigued by the final part, when in the ancient city of Petra, Indiana Jones found a certain famous cup. 
She decided to go to the site, as she wouldn't be surprised if this chalice was indeed resting in the underground of this city. 
She silently hoped that the riddles would be the same.
