A near Total Conversion for Fallout: New Vegas. Fallout: Project Brazil adds an all new story around a new player character, an adopted resident of Vault 18, embarking on a quest to a hidden complex 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.
