THE SHORT ANSWER

Mixu's Unlocker (MIXER) is a dependency named by a number of mods in this guide. It unlocks every faction for play and, more importantly, provides the framework that dozens of other mods (including Araby) depend on. If a mod's description says "requires Mixu's Unlocker," this is the one.

You will see "needs Mixu's Unlocker" on many mods in this series. This guide explains what it is and why it belongs at the top of your load order.

What Is Mixu's Unlocker?

Created by Mixu, MIXER is a startpos and utility mod that:

  • Makes all factions in Realms of Chaos and Immortal Empires playable.
  • Adds modder utilities (extra building slots, hero categories, and the hooks other mods need).
  • Acts as the dependency for a large ecosystem of content mods.

Without it, mods like OvN Lost Factions: Araby simply will not appear in your game.

The Wider Mixu Collection

Mixu also maintains a family of popular mods:

  • Mixu's Legendary Lords — adds extra legendary lords to many races.
  • Mixu's Moussillon — a fleshed-out Moussillon faction for the Vampire Counts.
  • Mixu's Faction Unlock variants — unlock specific factions.

These are optional, but they are the same author and share the same clean, compatibility-first philosophy.

How to Install

  1. Subscribe to Mixu's Unlocker on the Steam Workshop.
  2. Place it at the top of your load order in the Mod Manager — it is a framework, so it loads first.
  3. Subscribe to any mods that require it (e.g. Araby, the Crustacean Nation).
  4. Launch. If a dependent mod is missing, the manager's warnings will flag it.

Compatibility

MIXER is designed to be a quiet foundation — it rarely conflicts, which is exactly why so many mods build on it. Pair it with our basic QoL pack and you have a stable, expanded vanilla game.

Verdict

Install MIXER when a mod you want lists it as a requirement. It is not necessary for every mod in the Workshop.
