Catalyst Game Labs refits the seminal BattleTech IP with two new box sets and a rulebook for redeployment in August, and available at the Gen Con Game Fair 2026. The same game and universe you’ve loved for four decades receives its best-yet presentation of art, fiction, miniatures and rules.
For the first time in more than thirty years, a new BattleTech Starter Box, Core Box and Core Rulebook were developed simultaneously for a joint release in August 2026. In preparation for this refit, Catalyst ran the largest public playtest in BattleTech’s four-decade history, ensuring all revisions to our game of heavy metal mayhem were well-honed and battle-tested.
While rules changes were made to improve the tabletop experience, this is not a new edition of BattleTech. As always, BattleTech remains remarkably the same as when it first appeared in 1985’s Second Edition boxed set.
Starter Box
The Starter Box builds off of the success of the Beginner Box and Essentials, but ups the ante. As a starting point for new players, it eases novice MechWarriors into the BattleTech game as smoothly as ever. But now, the reverse of each half-page record sheet offers a taste of the exciting equipment and rules that the full BattleTech game brings to your table. The box includes two fan-favorite, ilClan-era BattleMechs: the dogged Hammerhead and the brutal Kontio!
Core Box
Likewise, the new Core Box uses the bestselling A Game of Armored Combat boxed set as the foundation to construct an immersive, fun experience. A highlight of the new Core Box is the Sagas lore booklet. This brand-new primer opens the doors to the BattleTech universe with a series of gorgeous, all-new art pieces, but also guides players through choosing a faction, a style of play, and more. The eight high-quality, ready-to-play miniatures included in the box represent a cross-section of more than thirty years of beloved BattleTech lore. They include the Hollander and Rakshasa that first appeared in Technical Readout: 3055; the Solitaire from Technical Readout: 3067; the Uziel and Mad Cat Mk II that premiered in the MechWarrior 4: Vengeance computer game; the Vulture Mk IV Prime that first hit game tables as part of MechWarrior: Dark Age; and the Regent and Eris from the new ilClan Era Recognition Guides.
Core Rulebook
Building on the critical and commercial success of the BattleMech Manual, a half-year of public playtesting brought forth the most cohesive, approachable, and dynamic set of rules for BattleTech ever: the new Core Rulebook. Thanks to the support of the Catalyst Demo Team Agents and the wider BattleTech community, the Core Rulebook also contains a comprehensive Missions section: a shared, fundamental framework allowing players to easily create a huge variety of BattleTech games. This flexible toolbox allows for everything from quick pick-up games to epic clashes, and makes it easy for anyone—from the newest players to grizzled veterans—to build a force, choose a mission, grab some miniatures and start rolling dice!
Core Rules Changes
After six months, five playtest packets, and thousands of hours of playtesting, we’ve finalized the BattleTech Core Rules Changes document, which you can find here, alongside a review and reflection on this process from developer Keith Hann. We can’t thank our fabulous, worldwide community enough for their expertise, enthusiasm, and time as we developed this new rulebook and box sets. Thank you!
As always, existing BattleTech mapsheets, Technical Readouts, and all models remain fully compatible with the new Core Rulebook. Additionally, of the thousands of ’Mech record sheet variants published over the past forty years, less than .05% required a small tweak (just those for units which have Watchdog CEWS or Bombast Lasers). Odds are that you’ll never see an existing record sheet that’s not fully compatible.
As usual, Catalyst is attending AdeptiCon 2026 in force! In addition to our plethora of games, we’ll have a diorama showing off the new BFM: Volcanic map, along with all of the new models found in the Starter Box and Core Box! We’ll also have samples of both boxes in our display cases, along with a complete sample of Aces: Snowblind, our next Alpha Strike cooperative campaign box, currently at the printers. Stop by the Grand Ballroom, snap photos, ask us questions and play some BattleTech!
For those not attending, we’ll be livestreaming throughout the show. Be sure to catch our first segment, at 10 a.m. CST, where we’ll extensively cover the details of this announcement, answer questions, and more. Check out all of the excitement youtube.com/@catalyst-game-labs.
