Crusade rules overview for Warhammer 40k: how a Crusade force works, what you track over a campaign, and how to muster your army in 10th.
GW promised free rules for just about every 40k game mode, but Crusade got the short end of that deal. The only free download here is a carry-over document that ports your existing Crusade force into the new edition, so if you’re mid-campaign, you’re covered. If you were hoping the free file would hand you fresh rules, missions, or Agendas for a brand-new Crusade, that’s the catch: those live in the paid Tyrannic War supplement and the Leviathan Core Book.
Updated on July 6, 2026, by Rob Baer with the latest on the free 10th Edition Crusade rules download.
Here’s how Warhammer Community framed the carry-over when the new edition landed:
Your Crusade force from the previous edition can be carried over into the new one with a simple document, available to download below.
So in practice, the free file is about keeping your existing campaign legal, not starting a new one. If you’ve already got a Crusade roster with battle honors and scars logged, it carries every one of those veterans over without rebuilding the whole thing from scratch.
Unfortunately, this document is all you get for free this time around, but it is enough to keep your crusade going. If you’re currently running a campaign, this is nice because you won’t have to stop and restructure the whole thing entirely.
Power Levels are gone too, so your Crusade now runs on points instead. The upside is that wargear upgrades cost zero points, so a unit’s listed value is the whole cost, which keeps the mental math close to the old Power Level feel. What you won’t find in the free file is any of the new rules, missions, or experience systems. Those you’ll have to buy in the Leviathan Core Book or a standalone Crusade supplement.
The bigger Crusade content lives in Crusade: Tyrannic War, the first proper supplement for the edition. It’s built around the Tyranid invasion of the galactic west, and it packs in Battle Traits, Crusade Relics, Blessings, Agendas, and 15 themed missions, plus two upgrade trees split between the monsters and the units hunting them. Best of all, it’s not locked to Tyranids or Marines, so any faction can run it. The catch is the same as everything else here: it’s paid, bundled into the Leviathan Core Book, or sold as a separate release.

Here’s the part you actually came for. The free Crusade carry-over rules are a straight download from the Warhammer Community Crusade article linked above, no purchase and no strings attached. Before you grab it, here’s exactly what’s inside and who it’s for:
- What’s in it: the carry-over rules that convert a previous-edition Crusade force into the current edition, with wargear upgrades now free and points replacing Power Levels.
- What’s not in it: new missions, Agendas, Battle Traits, Relics, or experience rules. Those are paid, sitting in Tyrannic War or the Leviathan Core Book.
- Who should grab it: anyone with an active Crusade roster who wants to keep playing without rebuilding from scratch. Starting a brand-new Crusade instead? You’ll want a full supplement.
