Fallout: Project Brazil mod is a full prequel campaign to New Vegas
Fallout: New Vegas deviated from the post-apocalyptic franchise's extreme isolationism by populating its ruins with lots of people, smelly dogs, and those freaking annoying butterfly-hornet things. The wastelands seemed alive—but the tale of how people flocked to New Vegas remains untold. Until now: The in-development Fallout: Project Brazil mod sets up the backstory.
"Project Brazil is a quieter, more harsh and severe world than Fallout 3 or New Vegas," writes modder Thaiauxn. "It feels like a real place spotted with rare moments of absurdity and fear, split between multiple rising civilizations all trying to fight for what they want or need in a world recovering from the Great War."
Easily earning the spotlight is the amazing intro cinematic seen above. Though the famous "war never changes" line isn't uttered by Ron Perlman here, the narrator's low growl sets the mood. Plus, he sounds slightly like Bane from The Dark Knight Rises. Don't you want Bane telling you the consequences of a world consumed by nuclear fire?
As Project Brazil's Mod DB entry states: "This mod adds an all new story around a new player character, an adopted resident of Vault 18, embarking on a quest to a hidden complex called 'Brazil' in the ruins of Los Angeles. Along the way, you'll discover a pitched battle between the Survivalist Army, the New California Republic, and The Super Mutants, which shapes the politics and events leading to the NCR's invasion of the Mojave. The story takes place in 2260—many years before the 'Courier' awakes in New Vegas, while the Enclave struggles to rise again on the West Coast."
Thaiauxn's plans to release several chapters starting sometime in the next few months, with the mod's first split into three parts. The full campaign will eventually contain 16 primary quests and "several side stories, all related to the player's journey through Vault 18 and the wasteland of San Bernardino." It's definitely a work-in-progress, though, and Thaiauxn is seeking additional help from writers, scripters, and modelers.
