Owlcat's third Rogue Trader expansion sends you on the galaxy's most dangerous museum tour, and the new cybernetic Augments system alone is worth the price of admission for build-obsessed CRPGers.

I've been deep in the Koronus Expanse since Rogue Trader launched, and The Infinite Museion is the first time a DLC for this game made me genuinely rethink a run I thought I had figured out. The expansion centres on Trazyn the Infinite, the Necron overlord beloved by lore fans for his acquisitiveness and peculiar sense of humour, and it uses that character as an excuse to drag your Rogue Trader through a vault of ancient artefacts while forcing confrontations with your own dynasty's buried history. It is, without question, the most cinematic thing Owlcat has shipped for this game so far, with high-production cutscenes that push the engine further than any prior content dared. The standout mechanical addition is the Augments system, which transforms cybernetics from cosmetic trinkets into genuine build-altering modifiers. If you have been running the same archetype since Act 1, this DLC will quietly invalidate some of your choices and open up directions you had not considered. Heretic-path players in particular get a meaningful upgrade here, with the new system feeding directly into the Heretical conviction track in ways that reward players who have been leaning into that alignment. The community consensus seems right: this is the biggest single mechanical shift the game has seen since launch, bigger even than the Blade Dancer and Executioner archetypes that arrived with the first DLC. The new companion, Eogunn Februs, is a tech-priest unlike his base-game counterpart Pasqal Haneumann. Where Pasqal is reserved and machine-brained, Eogunn is chatty, warm, and deeply unsettling in equal measure. His introduction involves stitching several fatally wounded soldiers into a single composite body to save something of them, which tells you exactly what kind of person you are dealing with. He has a sinister layer underneath the jovial exterior, and the banter between him and Pasqal is one of the DLC's quieter pleasures. For companions fans, he earns his slot in the roster. The criticisms worth flagging are real. Several reviewers and players noted bugs and performance hiccups at launch, which is a recurring Owlcat pattern that patches tend to address over time. The runtime also draws complaints: at roughly 12-15 hours of content, some players felt the Museion itself warranted more time, more exhibits to read, more argument between the two tech-priests. The story stays consistent from start to finish, which is genuinely better than either of the previous DLCs managed across the full five-act structure, but it ends before you feel ready to leave. That is half a complaint and half a compliment, depending on your tolerance for wanting more. For returning players who have already cleared the base game and either or both prior expansions, The Infinite Museion is a straightforward addition. The Augments system alone justifies revisiting an old save. For anyone who has not touched Rogue Trader yet, the correct entry point is still the base game, which remains one of the most ambitious licensed CRPGs released in years, combining turn-based tactical combat, a Dogmatic/Iconoclast/Heretical conviction system that actually shapes your dialogue and endings, colony management, companion loyalty arcs, and the grimdark atmosphere that Warhammer 40,000 lore fans will find almost irresistibly faithful to the source material.

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
