Crusader Wars CK 3 — The Mod That Lets You Fight CK3 Battles in Total War

Quick answer: Crusader Wars is one of the most radical mods in the CK3 scene: when your CK3 army makes contact, it exports the battle into a real-time battlefield in Total War: Attila, lets you personally command every unit card, then writes the casualties 100% back to your CK3 forces. It turns CK3's abstract battles into "a free Total War game bolted on." The catch: you need to own Total War: Attila plus three of its DLCs (Age of Charlemagne / Slavic Nations / Empires of Sand).

This guide covers how it works, the requirements, installation, and what the community thinks of it.

What This Is: A CK3 × Total War Bridge

(New to CK3's basics? Start with the CK3 beginner's guide — this mod only changes how battles play out; the strategic layer stays pure CK3.)

Here's the Crusader Wars gameplay loop:

  1. Contact: your army enters a battle in CK3 and a popup asks if you want to resolve it with Crusader Wars.
  2. Real-time command: the game launches Total War: Attila automatically, mapping your CK3 forces to matching Attila units by culture (legions, knights, levies, and culture-specific units all have counterparts). You command on the real-time battlefield.
  3. Results sync back: when the battle ends, casualty counts per unit are returned at 100% fidelity — commanders (generated as Total War generals from their rank/retinue/Prowess), knights, and levies all report their dead and wounded back into your CK3 save.
One-line summary

The official tagline is "Fight your CK3 battles in Total War: Attila." Its pitch isn't replacing CK3's strategy layer — it's adding hands-on command and spectacle to the combat layer.

Feature Highlights

  • Historical accuracy: the author mapped every CK3 culture/heritage/unit to a hand-tuned Attila setup covering 8th to 15th century equipment and troop evolution; the month you start a war determines the seasonal battlefield (winter effects, snow-affecting combat).
  • Terrain and sieges: siege battles are supported too (added in v1.3.0; grab it from the Discord).
  • No load-order headaches: Crusader Wars ships its own launcher that automatically manages mod toggles on the Attila side — you never touch Attila's mod manager manually.

Hard Requirements (Read Before Installing)

Need Notes
Crusader Kings 3 Base game only; no CK3 DLC required
Total War: Attila Campaign and engine foundation
Attila: Age of Charlemagne DLC Required (Charlemagne scenario unit pack)
Attila: Slavic Nations DLC Required
Attila: Empires of Sand DLC Required
Windows PC Officially supported; no Steam Deck or console support
All three Attila DLCs are mandatory

This is the most common deal-breaker: plenty of players own Attila but discover mid-install that they need three DLCs on top (and the bundle isn't cheap). Confirm you have all four titles before you start — otherwise you'll burn an afternoon for nothing.

Installation Steps

  1. Download the standalone launcher from crusaderwars.com (this is not a Steam Workshop mod — it's a separate program).
  2. Follow the site's instructions to drop the CK3 mod files into Documents\Paradox Interactive\Crusader Kings III\mod\ (or point the launcher at a "non-Steam" path).
  3. On your first battle, the launcher auto-generates CrusaderWars.pack in Attila's data folder and manages the Attila-side mods for you (no manual enabling).
  4. Play CK3 as normal; when an army makes contact, choose to resolve with Crusader Wars.
The battle resolution experience

The flow is "CK3 → switch to Attila, fight it out → auto-switch back." An entire battle can take much longer than the instant vanilla resolution — the community gripes about it ("one big battle = 20 minutes"). It's a price worth paying if you love Total War-style micro.

Compatibility: AGOT & Total Conversion Mods

  • AGOT (Game of Thrones): official compatibility is "Currently being developed," and the community already has working setups.
  • Realms in Exile (Lord of the Rings) / The Fallen Eagle: the official site lists adaptation paths; Realms in Exile has a dedicated Crusader Wars patch mapping Middle-earth units into Attila's LOTR mod (Dawnless Days).
  • Spin-off: the open-source Crusader Conflicts project rebuilt the whole system on Crusader Wars' ideas (more flexible unit mapping, dynamic battlefields) — different feel, solid backup option.
Watch it in action first

Search YouTube for "Crusader Wars CK3" — there are plenty of test videos (including AGOT runs of Robert's Rebellion). Watch five minutes before committing to the three-DLC purchase; whether this mod is for you depends entirely on how much you love Total War's manual combat.

Community Verdict & Common Gripes

  • Loved for: top-tier spectacle (personally commanding a Westerosi host assaulting a city), thoughtful culture mapping, precise result sync, and the "I actually get to play the battles" satisfaction.
  • Griped about: assembling all three Attila DLCs (expensive), slow battles, occasional stutter/crashes on the process switch, and fatigue from hand-managing every battle in the lategame.
  • Bottom line: Total War micro lovers = masterpiece; players who just want battles resolved fast = give it a miss.
