+# Medieval 2: Total War
+
+Medieval 2: Total War is a game from the [Total War](https://www.totalwar.com)
+series.
+
+## Mods
+
+### Third Age: Total War - Divide and Conquer
+
+[Divide and Conquer](https://www.moddb.com/mods/divide-and-conquer) is a submod
+for the [Third Age Total War](https://www.moddb.com/mods/third-age-total-war)
+mod.
+It is a Lord of the Rings themed mod, not only adding a large array of new
+units, castles and factions, but converting it to a setting based in
+Middle-earth.
+
+The installation guide for this mods is based on
+[Laetus'](http://www.twcenter.net/forums/showthread.php?724777-Third-Age-and-Linux)
+post in the Total War Center Forum .
+For installation the latest version needs to be downloaded from
+[MOD DB](https://www.moddb.com/mods/divide-and-conquer/downloads/).
+Following this run the executable (`.exe`) file and select not the game but a
+newly createt folder.
+If you are on linux use [wine](../linux/wine.md) for this.
+The executable will create many files in the directory.
+The important files are located in a subdirectory called `mods`.
+If you are on linux you need to rename all the files and directories under the
+`mods` folder to lowercase.
+This can be done by running
+`find . -depth -exec perl-rename 's/(.*)\/([^\/]*)/$1\/\L$2/' {} \;` after
+changing the working directory to the `mods` folder.
+This concludes the extra steps for linux systems.
+Rename the directory below the `mods` folder to `third_age`.
+`third_age` now has to be moved to the modding folder of Medieval 2: Total War.
+This folder named `mods` too can be found on the top level of the game
+directory.
+Lastly you need to change the launch options in steam.
+Open `Properties` of Medieval 2: Total War and set the launch options under the
+general tab to `--features.mod=mods/third_age`

+### Errors with the Wine prefix of a specific game
+
+The last ressort for fixing problems that are related to the wine prefix of a
+game is to delete the Wine prefix.
+For this the id of the steam game first has to be known.
+This is done by navigating to the steam website or the community page of the
+specific game.
+The URLs will have one of the following forms where the game id can be read:
+
+```
+http://steamcommunity.com/app/<game id>/
+http://store.steampowered.com/app/<game id>/
+```
+
+After that navigate to the place your steam games are stored.
+You can remove `<steam location>/steamapps/compatdata/<game id>` to reset the
+Wine prefix completely.
+It is recommended to keep a backup of the folder containing the old Wine prefix
+as it stores game saves and other important data, that can be useful.
