Note: this article contains minor spoilers for the 2010 game Fallout: New Vegas, as well as for season one of Prime Video’s Fallout series.

Prime Video premiered an explosive new trailer for season two of their Fallout series at today’s Gamescon, an annual event that game developers use to update audiences on upcoming projects — including adaptations for the small screen. The new trailer, along with a simultaneous press release, promises some exciting new encounters for Lucy MacLean and company, along with a mysterious figure longtime fans of the series are sure to recognize. (In case you missed it, the trailer is linked below).

While the first season of Fallout drew upon the entire game series for inspiration, season two seems to be placing increased significance on the events of Fallout: New Vegas, a 2010 entry that sees its protagonist (simply known as the Courier) navigate a post-apocalyptic power struggle between different political factions within the Mojave Desert for control of the Hoover Dam. One of those factions is known as the Free Economic Zone of New Vegas, led by Robert House, a staunch businessman played by Rafi Silver (Shameless, NCIS) in a season one cameo but recast for season two as Justin Theroux (Mulholland Drive, American Psycho). Having been among the few to anticipate and prepare for the nuclear war that has destroyed most of Fallout’s world, House rules the New Vegas Strip with an army of security robots, clinging to old world ideas of venture capitalism. He presents a complex ethical question to players of New Vegas, valuing scientific advancement over populist ideals: “if you want to see the fate of democracies,” he tells the Courier, “look outside the window.”

As whether the business mogul lives or dies depends on the Courier’s choices, whether House’s appearance will be relegated to The Ghoul’s pre-War flashbacks or he’ll re-materialize in 2296 is unclear, especially since Prime Video has been vague on which ending of New Vegas is canon to the events of the series. In the teaser, The Ghoul seems to imply that House is partially responsible for the show’s nuclear setting. “You wanna know why the world ended?” the mutated cowboy remarks. “It started here… with one man.”

In the company’s aforementioned press release, Prime Video also teased the appearance of a Deathclaw, a race of “terrifying post-apocalyptic predators” ubiquitous across the series. Between a host of new threats and returning ones, Fallout is setting up a world where the future belongs to those who fight for it. The new season will premiere on December 17th, 2025.
