Warcraft Total War is a total conversion mod for Medieval II Total War. Our goal is to bring the Warcraft universe into a Total War game. This mod will feature epic battles with units from the Warcraft universe and a new campaign that will cover the events of the Third War and beyond.
I've made it so that the Trolls can use all their units if you click on "All" in custom battles. They will also be able to recruit all the Trolls in the campaign if you conquer the other Troll factions, or if you take the areas of the Smolderthorne/Darkspear Trolls.
The campaign stuff isn't finished but it will be soon.
