Legends of the 3rd Age (formerly: Blue Wizard Mod) adds two new playable factions, Lothlorien and Moria, to The Battle for Middle-earth(tm). These factions come with a fully functional AI. It also enhances the original factions with additions and changes the gameplay. The focus here is clearly on multiplayer. Units and structures are designed to fit in the original game's style.
This will be possible in the next update :)
Woow cool!
