Fallout: Yellowstone Season 1 Episode 4 - Onward to Ruby Rockets

Our survivors have weathered the onslaught of the Flameborn Raiders and salvaged what remains of the battered traveling caravan. With grim resolve, they band together and press on toward Ruby Rocket’s Taphouse, their only hope of safety in the chaos of the Wastes.

Their path leads them through the Shadowed Ravine—once a proud stretch of highway, now a crumbling, sunken relic buried beneath the earth. Twisted asphalt and skeletal overpasses give way to a claustrophobic tunnel system, where flickering lights and ancient signage whisper of the old world.

But the real surprise waits below.

In the bowels of the ravine, the survivors uncover a forgotten pre-War laboratory, its halls pulsing with strange technology and cryptic terminals. Lines of code in an unknown language scroll endlessly across cracked screens, hinting at buried secrets and experiments long since abandoned—or merely sleeping.

Whatever this place was, it was never meant to be found.

Now, with the ravine behind them and Ruby Rocket’s growing closer, questions linger.
Who built that lab?
What did it contain?
And why was it hidden so deep?
