One of the biggest story mods ever made, this standalone campaign features an entirely new map with brand-new areas, starting inside Vault 18 and spanning the New California wasteland.Fight through an epic war between the NCR, Enclave, Raiders, and Super Mutants, complete with studio-quality voice acting, dynamic radio, and 8 unique companions.

Now on GOG!

In Fallout: New California you play as the kid from Vault 18. Orphan. Loner. Mutant. On the last big night of the Vault Ball season in 2260, you make a fateful decision that will change the course of your life -- and eventually the future of the New California Republic.

Vault 18 is at the heart of the California Wasteland high in the San Bernardino Mountains, and it's legendary Wasteland Scouts have managed to keep its secrets safe for decades despite the wars raging beyond the great door. In their old age, the Scouts have created a new generation to take their place... if their rebellious adopted kids survive the Enclave threat brewing within their own ranks.

You will face the New California Republic under president Wendell Peterson, the New Reno Mob's Bishop Family, the remnant Shi Clans, The Enclave Leonidas Squadron, the Super Mutant Army, and the bloodthirsty Raider Alliance that have banded together in the remote Athens-Tec Uranium Mine off the Long I-15.

Through them all you'll choose your path from SPECIAL dialog options, acquired PERKs, and travel with 8 possible companions depending on your choices. You'll enjoy two new radio stations with unique music, hours of voice acting, and professional grade presentation.

There is always another path to take in New California. But War? War never changes.
