Fires of the Sun image - Age of the Ring: A Shadow in the East mod for Battle for Middle-earth II: Rise of the Witch King
A Sub-mod for Age of the Ring 8.2 that expands Mordor into a broader "Sauron's Forces" with two Sub-factions, Mordor as one and a somewhat altered render of the Adventure faction of Rhûn as the other.
In Demo 0.2 of A Shadow in the East, Sauron's Forces players who choose Rhûn as their Force will be able to level an Iron Dragon Forge to level 2 and build these things. This is a Kûninax-gâshûn, or Fires of the Sun, cart. It fires a bundle of flaming arrows (separate image here) that knocks back and ignites enemies.
