Warhammer 40.000 Leviathan unboxing & review, open box on concrete background
This item was kindly provided by Games Workshop. Thoughts and opinions are our own.

Leviathan, the #New40k launch box for the 10th Edition of Warhammer 40,000, will be available for preorder starting Saturday, June 10, 2023, with official sale commencing two weeks later on June 24.

The box contains 25 Space Marine models, 47 Tyranid models, a brand-new transfer sheet, an exclusive Leviathan book that collects lore, core rules, the Tyrannic War Crusade supplement, and the Chapter Approved Leviathan mission cards.

Just like the Tyranids, all 25 Space Marine models are easy-to-build push-fit models. The Terminator sprues come with an alternate bare head for the Sergeant and a teleport homer. The Infernus Squad, featuring a sprue of five models included twice, allows for building one model as either a Sergeant or grenade-lobbing Marine.

While there are no alternate weapon options or optional bitz compared to the promotional pictures, the new Terminators are truly breathtaking and impressively large. A detailed scale comparison with previous Terminator models and power-armoured Marines can be found here:

The new transfer sheet is exceptionally cool, showcasing a variety of fresh icon designs. In addition to the well-known Ultramarines, Blood Angels, Dark Angels, and Space Wolves, it also introduces Imperial Fists for the first time.

Similar to the Space Marines, all the Tyranid models are push-fit monopose models. There are no weapon options or alternate bitz, and the Termagants come with Fleshborers only.

In my opinion, the new Tyranids are arguably the best Tyranid models ever released. They feature more defined and exaggerated musculature compared to their predecessors, with significantly enhanced texture on their carapaces. Moreover, the new Termagants boast updated proportions and now come on 28mm bases. Personally, they are my favourite models from the entire set.

Leviathan book & core rules first look

The comprehensive book is divided into various sections. It begins with a hobby introduction section that will be familiar to other Games Workshop core books. It also includes an extensive lore and background section that incorporates the latest events from the Arks of Omen series. Each army has its own dedicated showcase section based on their Combat Patrol sets. However, the highlight of the book is undoubtedly the new core rules.

At first glance, the 60-page rulebook is the most well-structured rules set I have ever read from Games Workshop. The new rules are clearly explained, featuring numerous diagrams, icons, and concise summaries. The order and structure of the rules are highly coherent and easily accessible. Surprisingly, I found it even more straightforward to follow than the 3rd Edition Age of Sigmar rulebook, despite the absence of numbered rule sections. The only missing component is a cheat sheet, and I can’t help but wonder why Games Workshop doesn’t provide these anymore.

The new 10th Edition Warhammer 40.0000 core rules can be downloaded for free over on Warhammer Community, so see for yourselves.

The book also includes the new Combat Patrol rules, which only occupy a few additional pages. The remaining contents delve into the Tyrannic War Crusade supplement, which will be published as a separate book outside the Leviathan box.

Coming up

Later today, we’ll treat you to a closer look at the new Terminator models, complete with a scale comparison spanning from 2nd Edition to the present day. Additionally, mark your calendars for next Saturday morning when the preorders go live, as we’ll be preparing an in-depth review of the Leviathan box contents. We’ll be covering the launch of the new edition with a couple of tutorials and will strive to paint as many of the new models as possible. Garfy, in particular, is thrilled to showcase his glorious retro-inspired Blood Angels scheme on the Space Marines. Stay tuned for more exciting updates!
