Owlcat has moved Warhammer 40,000: Rogue Trader’s final DLC, Processional of the Damned, to December 2026, introducing Stella, an unsanctioned psyker companion, and a Madness system that closes out the CRPG’s expansion arc.

December delay sets the shape of Rogue Trader’s finale
Warhammer 40,000: Rogue Trader’s final story DLC is now planned for December 2026 after Owlcat delayed Processional of the Damned from its earlier September target. In a Steam update quoted by Rock Paper Shotgun, the developer said that, despite efforts to deliver the expansion by September, it “won’t be ready in time,” adding that the new December 2026 release window “is not expected to move any further.”
That makes the timing the immediate story. This is being positioned by Owlcat, IGN, Rock Paper Shotgun, and FRVR as the last DLC for Rogue Trader, closing the support arc of a CRPG that launched in December 2023 and has since been expanded through paid add-ons and free updates. For players who have been waiting for a complete campaign before committing to a long run, December is now the date to circle, with the usual CRPG caveat that an integrated expansion can change the texture of a playthrough far earlier than its endgame.
IGN reports that, like the previous Rogue Trader expansions, Processional of the Damned will be integrated into the main game rather than existing as a detached post-campaign module. FRVR similarly says players will encounter and recruit the new companion during a normal playthrough. That matters for save planning because Rogue Trader’s DLC model has been about threading new companions, mechanics, quests, and encounters into the main campaign structure. A player starting fresh before December may miss the intended flow of the final addition, while someone waiting for the full package will get the complete version of Owlcat’s Koronus Expanse from the outset.
The expansion is Processional of the Damned, not a newly titled Miracles and Madness DLC
Some readers are likely to search this as Rogue Trader Miracles and Madness because the new material revolves around religious miracles, psychic instability, and a system literally called Madness. The confirmed title in the current reporting and Owlcat-linked materials, however, is Processional of the Damned. Rock Paper Shotgun calls it Rogue Trader’s story-concluding final DLC, IGN says it brings the game’s story to an end this December, and FRVR identifies it as the final expansion.
The distinction is worth keeping clean because the source material uses “miracle” and “madness” as thematic and mechanical language, not as the official expansion name. The new recruitable companion, Stella, is treated by her order as a miracle of the God Emperor, while the expansion also introduces a Madness feature affecting companions, with FRVR’s account of the press release describing madness as something that can alter battle behavior for friendly and enemy characters. Those details explain the search phrasing, but they do not rename the DLC.
There is also an older listing problem around timing. The Rogue Trader Wiki page on Fextralife, last edited August 31, 2026, still lists Processional of the Damned for July to September 2026 and names Steam, Epic Games, Windows, and Mac OS as platforms. That appears to reflect the previous release plan. Owlcat’s newer Steam update, as reported by Rock Paper Shotgun, supersedes the September target with a December 2026 window.
Stella is the final companion hook, and she is built around risk
The centerpiece of Processional of the Damned is Stella, a miraculist raised by the Ecclesiarchy and presented as the Rogue Trader unsanctioned psyker companion for this final expansion. IGN quotes Owlcat’s official description: Stella is a “frail-looking young woman raised by the Ecclesiarchy” whose order treats her as “a miracle created by the God Emperor Himself,” even though she is an unsanctioned psyker. Rock Paper Shotgun’s account adds the sharper lore contradiction: her order does not see her as a witch or mutant, but as a living instrument of divine will.
That contradiction is classic Warhammer 40,000 material, but for Rogue Trader it is also a party-building premise. Stella’s power is not being framed as a clean spell list or a safe support kit. IGN’s quoted blurb says she manifests unstable powers while shedding tears of blood and showing cracks in her porcelain skin. In battle, she produces psychic flares that deal area-of-effect damage around her. Rock Paper Shotgun also points to her Psychic Trail ability as a focal point for player choice.
The choice structure around Stella sounds deliberately uncomfortable. Rock Paper Shotgun reports that players can grow her and her Psychic Trail into a powerful weapon, try to save her, or lean into her “madness and damnation.” IGN’s version phrases the branches as forging Stella into a living weapon, making her a friend and ally, or diving into madness with her. The exact quest outcomes remain unannounced in the supplied material, but the shape is clear: Stella is designed as a progression dilemma, not a neutral recruit whose build path is separated from her story.
For a party RPG, that is the right kind of final companion pitch. Rogue Trader’s best character decisions tend to live where doctrine, utility, and affection grind against each other. Stella’s setup asks whether the player values battlefield output, personal rescue, or ideological surrender, and the expansion’s psychic danger language suggests that even optimized builds may carry narrative and mechanical instability.
Madness and the Zealot archetype point at combat pressure, not only story closure
Processional of the Damned is adding a new archetype, the Zealot, described by IGN as melee-focused and by Rock Paper Shotgun as centered on bludgeoning weapons. FRVR’s coverage says Owlcat notes the Zealot will bludgeon enemies to death, although one sentence in FRVR’s article phrases this as the class bludgeoning “players,” which is best read cautiously as a wording slip rather than a confirmed PvP or enemy-only feature. The consistent detail across sources is that Zealot is a close-quarters, blunt-force archetype.
The more interesting systemic addition is Madness. Rock Paper Shotgun and IGN report that the feature affects all companions. FRVR adds that the mechanic can infect friendly and enemy characters and may cause them to hurt themselves or others, changing battle dynamics. If that description reflects the final implementation, Madness could become a disruption layer in fights that otherwise reward tightly scripted alpha strikes, defensive positioning, and carefully stacked buffs.
FRVR notes that one common complaint about Rogue Trader has been its relatively easy combat, and says the Madness system appears aimed at adding complication and tactical texture. That is an interpretation from FRVR rather than a balance promise from Owlcat in the provided text, but it is a plausible design direction. A party-wide instability system is especially potent in Rogue Trader because build planning often depends on reliable sequencing: officers enabling key turns, damage dealers cashing out buffs, and support characters keeping momentum under control. A mechanic that can interrupt behavior or punish clustered formations would make the final DLC feel different from a simple content pack.
The new enemy roster also points toward variety. IGN and Rock Paper Shotgun report new enemies from the ranks of the Arch Enemy and the Aeladari. FRVR repeats that wording. The supplied material does not list specific units, bosses, resistances, or encounter rules, so any build recommendations beyond broad caution would be premature. Players planning a December run should expect the expansion to test both melee engagement and psychic-risk management, but the exact meta impact will have to wait for patch notes or hands-on play.
Refunds, saves, and platform details need careful reading
Owlcat is offering refunds to Season Pass 2 owners through Steam customer support because of the delay, according to the Steam update quoted by Rock Paper Shotgun. The refund is not frictionless from a save-management perspective. Owlcat warns that refunding Season Pass 2 on Steam will remove both Processional of the Damned and The Infinite Museion from the user’s Steam account, and that it will break any saved games made with The Infinite Museion DLC content activated.
For anyone mid-campaign, that is the practical warning to take seriously. Owlcat says players who refund but want to continue a previous save using Infinite Museion content will need to obtain The Infinite Museion separately. The Appearance Pack included in Season Pass 2 will be made free and integrated into the base game for everyone, and Owlcat says that pack will not affect saves. The studio also notes that this change will come slightly later to other platforms.
Platform information is less tidy across the available sources. FRVR reports that Warhammer 40,000: Rogue Trader: Processional of the Damned will release simultaneously on PC, PS4, PS5, Xbox One, Xbox Series consoles, and Nintendo Switch 2. The older Fextralife wiki page lists only Steam, Epic Games, Windows, and Mac OS alongside the now-outdated July to September window. Given the timestamp and the outdated release window on that wiki entry, readers should treat FRVR’s newer platform claim as the current reported plan, while still checking their platform storefront before buying or refunding anything.
No price for Processional of the Damned is stated in the supplied source material. The sources confirm Season Pass 2 ownership, Steam refund handling, and the relationship between the final DLC and The Infinite Museion, but they do not provide a standalone price for the December DLC.
Owlcat is closing Rogue Trader while its Warhammer future expands
The finality of Processional of the Damned lands differently because Owlcat is not stepping away from CRPGs or from Warhammer 40,000. IGN reports that Rogue Trader’s writing, characters, narrative reputation, and commercial success helped raise Owlcat’s profile and led to another Warhammer 40,000 CRPG from the studio, Dark Heresy. IGN also notes that Owlcat is working on The Expanse: Osiris Reborn, a project described there as a departure for the studio.
That puts Rogue Trader’s December DLC in the role of a handoff. On one side, it has to finish the Von Valancius campaign’s expansion cadence with enough weight to justify being called the final chapter. On the other, it arrives while many players are already watching Owlcat’s next moves, including Dark Heresy. A final DLC built around an unsanctioned psyker, Ecclesiarchy denial, companion corruption, and party-wide Madness is a fitting stress test for the studio’s strengths: dense systems, consequence-heavy companions, and lore conflicts that become build decisions.
The unanswered questions are still meaningful. Owlcat has not, in the supplied material, detailed the length of the new questline, the full Zealot progression tree, the exact Madness rules, or how Stella’s different paths resolve. We also do not yet have performance guidance for the final DLC across platforms. What is confirmed is enough to plan around: Warhammer 40000 Rogue Trader final DLC support now points to December 2026, the expansion is Processional of the Damned, Stella is its volatile companion anchor, and anyone concerned about save continuity should be very cautious before using the Steam refund option.
For completionist-minded players, the cleanest route is likely to wait for December if you want one integrated campaign containing every companion, mechanic, and questline. If you are already deep into an Infinite Museion save, Owlcat’s own warning makes patience safer than refund experimentation. Rogue Trader’s last voyage now has a later departure, but the shape of it is finally visible: blood, faith, warp risk, and one last set of choices about whether power is worth the damage it leaves behind.
