Getting Started with Total War: Warhammer III Modding

Total War: Warhammer III modding is Workshop-first, conceptually simple, and well-tooled. The in-game launcher includes a Mod Manager tab; toggle, reorder, launch. Mod authors use Creative Assembly's official Assembly Kit and the community RPFM tool.

This guide walks the standard install on current WH3 (Immortal Empires + recent DLC).

Step 1 — Subscribe via Workshop

Open the Total War: Warhammer III Workshop. Subscribe to mods.

Three popular first picks:

• Mixu's Unlocker — unlocks the legendary lord pool for cross-faction play.
• Steel Faith Overhaul — comprehensive combat rebalance; substantial gameplay change.
• Better Camera Mod — quality-of-life camera adjustments.

Step 2 — Configure in the Mod Manager

Launch Total War: Warhammer III. The launcher (which appears before the game starts) has a Mods tab. Toggle your subscribed mods and drag to set load order.

The cardinal rule: later mods override earlier ones. Compatibility patches go after the mods they patch.

Step 3 — Click Play

The launcher's Play button uses the active mod set. WH3 loads with your mods.

The main menu's bottom-left corner shows mods are active. The faction selection screen reflects mods that add new factions or rebalance existing ones.

Step 4 — Immortal Empires vs Realm of Chaos

WH3 has two campaign maps:

• Immortal Empires — the unified Warhammer trilogy map. Most modded play happens here.
• Realm of Chaos — WH3's original campaign with Chaos-focused mechanics.

Most mods support both, but some are Immortal Empires-only or vice versa. Read mod compatibility notes.

Step 5 — DLC and trilogy content

Total War: Warhammer III's Immortal Empires incorporates factions from WH1 and WH2 if you own those games. Mods generally assume the full trilogy.

If you only own WH3, you'll have a smaller faction roster and some mods may be unavailable (factions they depend on weren't in your install).

Common gotchas

• Mod loaded but no effect. Check load order. A later mod is probably overriding the desired one.
• Two mods touching same units conflict. Use a compatibility patch (most popular mod combinations have one) or pick one.
• Patch broke my mod. Wait for the author to update. CA's patches are frequent; the community catches up fast.
• Multiplayer with mods. All players need the same enabled mods. The lobby coordinates.
• Save game corrupted. Mod list changed mid-save. Re-enable the original mods.

If you've never played Total War vanilla, modded WH3 with a major overhaul like Steel Faith is genuinely hard. Play 20+ hours vanilla first to understand the systems, then add mods.
