: Since you are not using the Steam launcher's mod manager, you must manually tell the game to load these files:

: Identify your game's installation directory (e.g., D:\Games\Total War Attila\data\ ).

: It is highly recommended to have a clean, unmodded version of Total War: Attila .

: You will need approximately 12–14 separate .pack files, including scripts, campaign base packs, and multiple model packs. Manual Installation Guide
