Story

As Lara is lost in Egypt, presumed dead, her closest friends gather to share stories of her previous adventures. Winston begins with the story of how Lara Croft found the Philosopher's Stone in Rome, Italy. It begins with Lara attending an opera; in fact she is there to meet with Pierre DuPont and Larson to exchange money for the Mercury Stone. The two men have other ideas and try to take both the money and the stone however Lara manages to grab it and escapes with elegance. A chase in the streets leaves Larson and Pierre in a car crash whilst Lara gets a head start on her adventure.

​Working her way through the Streets of Rome as morning dawns, Lara finds a doorway in a large wall. On the front are four item receptacles; one of them already has part of a key in it, the other part is the stone that Lara is carrying. After Lara collects the second key - the Saturn Symbol, she returns to the locked door. Pierre and Larson are waiting for her, and despite Lara's best efforts to warn him otherwise, Larson inserts the Saturn Symbol into its receptacle. He is then zapped with a magical fire and has caused the gate to realign itself, needing the last two stones shortly after or else it will explode. She leaves them and heads to Trajan's Market. Here, Lara fights the Mechanical Head of the Roman God Mars and a large Roman Soldier statue, collecting both the Mars Symbol and the Venus Symbol. After picking it up, she heads back to the doorway to put it in, but Larson is waiting. After a short gunfight, the three dragon gargoyles that guarded the gate come to life. Lara destroys them and puts the stones into the receptacles; the door explodes open, leading Lara to a false Philosopher's Stone. As Lara approaches, a trap door opens and she slides down into the darkness. She finds herself on a lower floor in the Colosseum where Lara's skills are put to the test when she has to find more puzzle items as well as battling against lions and gladiators. Along the way Lara sees Pierre. As usual, they don't part on good terms and Lara lets him fall into a deep chasm. She continues on to a higher floor and battles another Roman Soldier statue before opening a door and discovering the true Philosopher's Stone. Using the crowbar, she prizes it from the wall.

Charles Kane is next to share his story about how Lara found the Spear of Destiny that had been buried with a sunken WW2 submarine. The cutscene then shows Charles telling Lara, as they stand outside of a Russian Base in Zapadnaya Litsa, that most of the men inside are ex-KGB as well as there being a nuclear submarine housed in one of the dockyards. She runs off and enters the base, making her way to the dockyard where she runs aboard the sub, hiding in the storage room. She is discovered and Admiral Yarofev asks two sailors to imprison her in a cell. In typical Lara style, she escapes and discovers that Mikhailov, the head of the Russian mafia, also wants the Spear. She uses a deep sea diving suit to explore the wreckage of the sunken u-boat; she finds it but when she takes it back onboard, Mikhailov is waiting for her. She is forced to hand it over but as she is about to be taken to the torpedo room, he is frizzled by the Spear, causing the lights to flick off, giving Lara a brief moment to take care of the men. The submarine has sustained considerable damage and is now sinking. She finds Admiral Yarofev, who is injured and he tells her to leave through the escape pod. She needs to find the oxygen and nitrogen tanks first, and as she offers to help him into the pod, he declines, choosing to stay with the sub. She escapes on her own without the artefact whilst Charles watches and waits for her return.

Father Patrick Dunstan recalls a story of how a young Lara followed him to the Black Isle whilst during her stay in Ireland with Winston. She helps the corpse of a hanged man by finding his heart: discovering it in the roots of the World tree, the one he's hanging from. On her return to the hanged man, Lara sees Father Dunstan banishing demons, learning that iron will banish many demons. He heads off on his own and Lara goes to return the heart. Going through the newly opened door, she soon finds herself in an abandoned church, and watches as a ghost turns a handle and disappears. 

She has to avoid the spirits of skeletons who try to stop her and make her way to the Labyrinth. Here, Lara has to figure out the right switches to throw that will give her access to the Bestiary. Finding her way out of the Labyrinth with the book, she enters another room through an upright coffin and sees Father Dunstan again. His hair is now white and he takes her to a safe place, advising her to stay out of trouble. When Lara tells him that she found a book with protective symbols, he tells her that she could draw them on the ground in front of them if they had the means to do so. 

After finding some chalk, Lara draws the symbols on the ground but is interrupted as a horseman appears and tries to attack her. Father Dunstan interferes but is knocked out by the horseman and taken away. Lara later finds the horseman again, who barters with her that if she stops the flow of water, he will spare the priest. Lara gains access to an Old Mill and uses a lever inside to slow down the water current outside, and later, a turn valve to stop the water entirely. She heads out and the horseman is now free, but he moves to attack Lara with his sword. Father Dunstan tells her to read the names from the book to take control of the demon as he battles him. She manages to find the right one, Verdilet, which causes him to freeze still before she then banishes him. Lara and Father Dunstan then decide to head back to the main island.

Winston takes Charles Kane and Father Patrick Dunstan into Lara's trophy room where they reminisce on how she obtained the Iris. With the help of Zip, Lara breaks into Von Croy's business 'Von Croy's Industries'. Here she makes her way through the ventilation ducts to sneak past most of the guards, reaching the 13th Floor. She finds the Iris and picks it up. Whilst escaping, Zip tells Lara that she has to ditch her weapon before passing through the scanner. As she is taking an elevator up to the roof, the cables are cut off and it falls to the bottom of the elevator shaft. She has to make her way back up on foot. The guards know that she has taken the Iris and are hot on her heels. She uses the Iris in a teleporter room to escape most of the trouble and it is from here that Lara knows that she must make her way up to the roof via the outside fire escape walkways. Reaching the highest walkway, Lara heads into a large room where there is a doorway that leads to a helipad. In order to open the door, she finds two pieces that make up the key to the door, battling two cyborgs along the way. With the door now open, she sprints across the roof, using her original hand glider to glide away from the building.

Back in present time and in Egypt, Von Croy has hired a team to help search for Lara. A worker approaches him to say that they have found something - her backpack, which gives him hope that she is still alive.
