All the Total War Series games are modifiable to an extent, but the ease, scope and manner of possible modifications varies between the games. The popularity of the modifications has contributed to the Total War games' ongoing success.

This page is not the place to find modifications, please refer to each individual game portal or Category:Mods for that, here you will find links to advice on how to make your own modifications.

Warscape Engine Modding Overview

Total War: Three Kingdoms


Total War: Three Kingdoms benefits from an Assembly Kit released by CA, the kit includes Dave (for database editing), Terry (for battle map creation), BoB (for compilation of pack files), and the Variant Editor (for editing unit model collections), read more here. To find the kit go to the 'Tools' tab in your Steam account.

TW Engine 2 Overview

The TW Engine 2 was used for Rome: Total War and Medieval II: Total War, there are similar tools and principles used in modding these games. Compared to the Warscape games RTW and M2TW allow much greater modding potential including the possibility of making "Total Conversion" mods including completely new campaign maps.

Once familiar with modding one of the games you will find it relatively easy to mod the other. The methods for changing the campaign maps are almost identical and many text files such as export_descr_buildings.txt and export_descr_unit.txt which control unit recruitment are also almost identical. However, some recognisable files from RTW which still exist in the base M2TW files such as descr_daytypes.txt confusingly are not actually used by the M2TW game engine!


Medieval II: Total War


Medieval II: Total War allows easy modification of many elements by straightforward text editing. The campaign map for M2TW can be modified by altering .tga image files and text files. Battlemap unit models and settlement structures can be edited via user-created tools many of which export and import to Milkshape ms3d files.

M2TW provides a system of mod-foldering to help avoid over-writing the base files. Geomod is a recommended resource to start modding on a bare but fully functional mod-folder of your own.

The M2TW game engine provides an automated system for the generation of unit sprites, but not vegetation sprites, IWTE can be used to create vegetation sprites and amend the descr_vegetation.db which does not auto-regenerate. The descr_geography_new.db file can be made to re-generate but there are drawbacks.

For further modding information see:


Rome: Total War


Rome: Total War allows easy modification by text editing for many elements such as; unit stats and recruitment, character traits and diplomacy. The campaign map for RTW can be modified by altering .tga image files and text files. Unit recruitment, character traits, diplomacy and many other aspects can be modified by changing text files. Battlemap unit models and settlement structures can be edited with the help of tools such as the CAS Importer/exporter for 3ds max (by Vercingetorix).

The RTW game engine provides an automated system for the generation of unit and vegetation sprites. The engine will also regenerate a modified descr_vegetation.db file and descr_items.db (for battle-map structures), the descr_geography.db file will not regenerate.
