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.
We only have 1 in-game cinematic other than the intro and outro narrations.
Honestly, I could have designed a game without the need for one of these, but live and learn. :p
If you played part 1, this replaces that dream that everyone hated, and helps to illuminate the events surrounding the Enclave attack that wasn't well understood last time.
