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.
Helm's Deep siege
looks like it was taken exactly from the Two Towers game for the PS2 :) They should remake those games with bigger maps for each mission and more soldiers(for each side)
