In the pantheon of modern action-adventure games, Shadow of the Tomb Raider stands as a gritty culmination of Lara Croft’s origin story. It is a game about pressure: the pressure of a looming Mayan apocalypse, the pressure of Lara’s own hubris, and the pressure of scarce resources in deadly, vertical jungles. For the purist, this friction is the point. But for a growing segment of the PC gaming community, the ideal experience is not found in the game’s default difficulty sliders, but in a third-party executable known as the "Fling Trainer."
