1up: "What's the game about? The Saboteur shows the consequences of pissing off a daredevil Irishman during World War II. For a refresher: The Saboteur focuses on Sean Devlin, a racecar driver who suffers a personal tragedy, and soon joins the Special Operations Executive to conduct a guerrilla campaign against the occupying Nazi troops in Paris.
Like the Mercenaries games, The Saboteur is an open-world third-person action game, but with a bit of an Okami twist. The occupied parts of Paris are rendered in black-and-white -- representing a low "Will-to-Fight." As Sean completes missions, he raises the Will-to-Fight, and therefore, adds color and vibrancy to the Parisian cityscape."
