The Koronus Expanse is about to receive a harsh lesson in justice.
Developer Owlcat Games has unleashed Lex Imperialis, the second major story expansion for the critically acclaimed CRPG, Warhammer 40,000: Rogue Trader.
This substantial new chapter brings the unyielding authority of the Adeptus Arbites to the forefront, challenging Lord Captains with a new 15-hour storyline, a formidable new companion, and dynamic new gameplay mechanics.
Available now across PC, PlayStation 5, and Xbox Series X|S, this expansion promises to test the loyalties and tactical acumen of every player who dares to traverse the lawless voids of space.
Enforce the Lex Imperialis
Priced at £14.99, the Lex Imperialis expansion thrusts players directly into the iron grip of Imperial Law, exploring its complexities and consequences.
Immerse yourself in a tense, 15-hour narrative where your choices as both judge and judged ripple throughout the Imperium. You will delve into the intricate and vital process of the Grand Harvesting, experiencing firsthand the grim responsibility of collecting the Imperial Tithe.
The severe consequences that await those who interfere with this sacred duty will shape the destiny of the entire Koronus Expanse and unravel dark secrets of the von Valancius dynasty.
An Uncompromising Companion
This expansion introduces a brand-new companion: Solomorne Anthar, a seasoned Arbitrator from the Adeptus Arbites. His unwavering dedication to Imperial justice is matched only by his simmering anger towards criminals.
Accompanied by his loyal, ferocious cyber-mastiff, Glaito, Anthar offers not only formidable combat skills but also a deeply personal romance option and a troubled past for players to uncover.
Dynamic New Mechanics & The Adeptus Arbites
Lex Imperialis redefines battlefield dynamics with new tactical options. The Familiars system allows players to command a majestic cybernetic eagle – a living embodiment of the Aquila – while your new companion directs his powerful cyber-mastiff. These battle companions dramatically reshape combat encounters.
You will also face the Adeptus Arbites faction. These incorruptible enforcers arrive equipped with their signature wargear – shotguns, suppression shields, and power mauls—embodying their elite status and relentless pursuit of order.
Season Pass 2 and the Future of the Expanse
The arrival of Lex Imperialis also comes with news for the future. Owlcat recently announced Season Pass 2 for Warhammer 40,000: Rogue Trader. This upcoming pass will bundle two more major story expansions and an appearance customisation pack.
Future adventures will include delving into a Necron vault curated by the iconic Trazyn the Infinite and exploring the surreal voidship graveyard known as the Processional of the Damned.
More Polish for the Koronus Expanse?
This new wave of content adds even more depth to the already massive CRPG experience.
In our 4/5 scored review of the base game, we praised its core strengths but noted room for improvement: “The story, the background lore of the universe and the combat are all highlights. On the flip… there have been a few bugs during my playthrough… with a little more polish Warhammer 40,000: Rogue Trader could have been a strong contender as a genre leader, but as it is, we have to pull back on that a bit. Yet still, if you like Warhammer or CRPGs, this is an easy sell.“
The release of a major, story-driven expansion like Lex Imperialis not only adds more of the excellent story and combat that fans love but also demonstrates Owlcat’s continued commitment to supporting and refining the game for its dedicated community.
The law is absolute, and judgment has arrived in the Koronus Expanse.
Whether you choose to uphold it, bend it, or shatter it completely, the Lex Imperialis expansion offers a compelling and unmissable new chapter for every Lord Captain. It is available to purchase now from the likes of the Xbox Store and more.
