For the Space Marine faction, the set includes a Ballistus Dreadnought, an Apothecary Biologis, a Captain in Terminator Armour, a Librarian in Terminator Armour, a Lieutenant in Phobos Armour, a Sternguard Veteran Squad, an Infernus Squad, and a Terminator Squad.
For Tyranid enthusiasts, the set offers a Winged Tyranid Prime, a Neurotyrant, a Screamer-Killer, three Von Ryan’s Leapers, numerous Termagants, several Neurogaunts, five Barbgaunts, and a Psychophage.

What’s In The Warhammer 40K Leviathan Boxes?
Veteran players will remember what happened with the Indomitus launch for 9th Edition, when pre orders vanished in under an hour and Games Workshop had to step in with a made to order wave so everyone who wanted a box could get one. Leviathan is positioned in the same way. It is the flagship box for 10th Edition, it has all-new miniatures on both sides and it is the ideal on-ramp for the rules.
That combination usually means high demand and very limited day one stock at local game stores. Anyone who missed Indomitus will not want to repeat that mistake here.
What makes Leviathan such a big deal is the value stack. Indomitus had 62 miniatures. Leviathan goes further, with 25 Space Marines and 47 Tyranids for a total of 72 models, plus the hardback rules and mission deck.
Based on the prize value listed in the GW newsletter giveaway at the time, the expected retail was around 245 USD, which is higher than Indomitus but still in line with a true edition-launch box rather than the 300 USD tier we have seen on other big sets. On top of that, Games Workshop has already said the two halves of the box will be usable as full Combat Patrol forces once 10th Edition lands, so you are not just buying a collector’s piece, you are buying two ready-to-play armies for the new format.
Beyond the box, a release roadmap extends until Spring 2024. This summer, Games Workshop plans to release a separate book containing the Crusade section of the rules. In the fall, codexes for Space Marines and Tyranids will be released, followed by Adeptus Mechanicus and Necrons in the winter.
T’au, Orks, Chaos Space Marines, Adeptus Custodes, and Dark Angels are slated for Spring 2024.
Notably, codexes are not mandatory for gameplay, as a comprehensive set of Index Cards with data cards for each unit will be available for download on day one. In addition to the Warhammer 40K 10th Edition content, a mysterious teaser hints at a “Battle on a New Scale.” While uncertain, this could suggest the introduction of a new spin-off game, akin to the former Epic 40K with its smaller 6mm miniatures.
On the other hand, it could utilise the 8mm scale found in Adeptus Titanicus or adopt a comparable approach.
