We have recently had a Grand Revision of the production schedule here, so it seems like a good idea to kick of 2026's schedule early!
One note of caution - we are in the midst of searching for a new Layout Artist. If they join us relatively quickly, expect a new round of changes and consider this schedule a work-in-progress. However, it will mean that some new things will appear and other things will get bumped up the release schedule. So, fingers crossed we find someone soon!
Please note that release dates listed here are expected PDF releases and pre-order dates - printed editions will likely appear 3-4 months later. Though we will be updating this particular post rather than appending more, you are welcome to make comments and ask questions in this thread!
Oh, and expect to see a lot more detail in the forthcoming State of the Mongoose this year...
November
The Relief of Novy Kyiv: A PDF-only release, this is a complete adventure that can be inserted into the Invasion campaign (Invasion was just too big to fit even into two books!). Kontr-Admiral Serhiy Borodin and the besieged colony of Novy Kyiv have need of the Travellers in a tale with a distinctive Ukrainian feel to it...
December
Cluster Truck: For centuries the Truckers have kept the worlds of the Estuary Cluster connected. Long years, hard years, but proud years. Trucking is a way of life, even if it ends with a Trucker’s Wake. Now the corporate shipping lines want to take over the spacelanes. Canaveral Station is under blockade, rigs impounded and crews in the slammer. The only thing left to do is hold a wake for a way of life. This is a complete campaign that will see your Travellers take command of their own small craft, hauling cargo across a system. They will steal potatoes, get covered in frozen beer in deep space, take part in a history-making riot, uncover corporate skullduggery, and smash a blockade while confounding local law enforcement!
February
The Core Expeditions: The Zhodani expeditions towards the galactic core are perhaps the greatest exploratory endeavours Humaniti has ever attempted. What drives them? What have they encountered? What is it like to be part of their scouting fleets or outpost building crews? Take part in pushing back the frontier on the very cutting edge of Charted Space.
Vehicle Handbook Update 2026: With both vehicle rules and the construction system re-written from the ground up, the Vehicle Handbook Update 2026 is not just a graphical update but a complete replacement for the core vehicle rules for Traveller. Expect a mighty tome from fan-favourite Geir Lanesskog comprising a multitude of new options, from humble push bikes and horse-drawn wagons, to aerospace interceptors, land ships and floating cities!
April
The Infinity Suite: The Infinity Suite will be the most perfect musical piece in the history... once it is finished. Right now the Travellers are MCr75 in debt, being chased by repo crews who want their illegally modified starship back, facing a career-ending plagiarism lawsuit... and the Suite is a musical shambles. Arriving in the Islands subsectors just ahead of their problems, the Travellers need to make a name for themselves and find the inspiration to finish the Suite. On the way they must deal with the usual rock 'n' roll problems - planetary revolution, interstellar conflict, fanatical cultists intent on murdering them, and the odd runaway cow.
Traveller Rules Compendium: Losing gaming time to tracking down that obscure little rule in a supplement? The Traveller Rules Compendium, headed by Geir Lanesskog, compiles all those rules systems from across two editions of Traveller, updates them, adds some more, and then lets you browse for the perfect rule at the perfect moment during your campaign!
May
The Vehicle Catalogue: Packed full of vehicles of all Tech Levels, The Vehicle Catalogue explores just what is possible with the new Vehicle Handbook 2026! Whether your Travellers need a taxi across town, the latest in grav speeder technology, or a fully armed and armoured gunship, they will find everything they need in The Vehicle Catalogue!
June
Aliens of Charted Space Vol. 1 Update 2026: This was one of the very early books released for this edition of Traveller - and so it is time for an Update to these ever-present aliens. Expect glorious new artwork throughout, a thorough update of ships, vehicles and weapons... and maybe some tweaks to the aliens themselves...
Brushfires: Any great empire will find itself embroiled in ‘brushfire wars’ among its possessions and colonies. Forgotten by most citizens, these conflicts flare up and sputter out over time. Now, against the backdrop of the Fifth Frontier War, the brushfires of Aramis threaten to consume the whole Towers Cluster. Brushfires sees a crew of independent Travellers follow a simple job straight into the heart of an erupting warzone, where they will see great heroics and villainous opportunists as they try to thread their way through the fighting.
The Aslan Hierate: The next 'empire' book to land for Traveller, this mighty tome covers all things Aslan, from commerce, to warfare, to clan politics. This will be the resource for adventures into the Hierate, all carefully curated by Aslan expert Randy Dorman. Also includes a good detailing of Hlakhoi sector.
July
Nous Voila (working title): A trilogy of adventures set on the world of Nous Voila on the French Arm, together with a gazetteer of the planet. Your Travellers will find themselves caught between intelligence agencies and terrorists, investigating a murder on a world-spanning airfilm train, and being cut off in a remote lodge during the dead of winter while surrounded by creatures that may not be entirely natural.
September
Consular Envoy: A hundred days out of Cronor Naval Base, diplomatic transport vessel Sifrshonz meets disaster. Ambushed by an Imperial cruiser, the ship and her mission are wrecked. With the command crew and Consular Envoy dead, the Travellers must decide: do they turn for home or plunge into the Outrim Void seeking a way to somehow complete their mission? Their voyage will take the Travellers to the dead world of Ganulph, and to mysterious Belgard where they will unlock a secret hidden for five centuries.
October
Fleets of the Minor Powers: Focus naturally falls on the big players of the Fifth Frontier War. However, there is a lot more filling the void with lasers, missiles and particle beams than just the Zhodani Consulate and Imperial Navy. This book takes a look at the fleet structures, doctrine, actions and ships of the more minor powers involved in the war - the Sword Worlds, Darrians, Vargr, Federation of Arden and some of the mercenaries taking part.
November
The Fall of Lanth: Lanth lies on the far side of the Abyss Rift, facing the Sword Worlds Confederation. Its naval base is a bastion against an offensive across the rift and into the Spinward Main. Caught planetside as the invasion fleets arrive, the Travellers witness a planetary invasion from far too close. They will see a proud city pummelled to ruins around them, witness triumph and retreat, and perhaps alter the fate of the world.
