LOTR-TW is a Total Conversion for Alexander TW based on The Lord of the Rings trilogy, focused to recreate the epic battles seen in the movies. It has a complete Middle Earth map, fully customised cities like Minas Tirith and Helm's Deep on Battle and Campaign map, a set of Historical Battles where you can play all the major and minor battles that take place in the trilogy, and a quest line for the Free-People's campaign where, if the player succeeds, will take the Ring-Bearer from Hobbiton to the wasteland of Mordor in an attempt to save the world from its doom.
The 3.02 all-in-one release includes a few minor bug fixes - edits to the trolls coding to prevent exotic crashes is one.
The "Campaigns Addon" sub-mod also includes a pretty wide variety of patching, additons, and fixes (one of which is fixing the troll voices and battlecry!) and can be found here for now:
