Fallout: New California adds an all new story around a new player character, an adopted resident of Vault 18, embarking on a journey through the wastelands of the New California Republic's Cajon Pass. An unofficial prequel to New Vegas, FPB adds hours of new gameplay and a fully voiced stand alone campaign.
One can transition from being indoors, and outdoors, without loading screens. Bethesda's system of Cell differentiation broke realism entirely, but was necessary on the scale of The Wastelan to save space and LOD optimization. Because Project Brazil takes place in KotoR style canyons, this transitioning between cells is no longer necessary.
Great Picture!
It was a very cool moment. I'm glad you enjoy it!
