Also known as Horse Rats, Tunnel Rushers are believed to be a failed experiment of Clan Moulder. These six-legged monstrosities were designed to be beasts of burden, applying the strength of the Rat Ogre to pulling mine carts, chariots and Screaming Bells. Clan Chieftains quickly realised, however, that an equal weight of slaves eat far less and are far more motivated by fear, so the Rushers were let loose. Somehow they have survived and the Skaven now occasionally use them for food. Although terrifyingly fast, they tend to panic in battle, and as they only eat refuse they are of little threat to man or beast. However, a raging stampede of them can panic an entire army, and the Skaven use this fact to their advantage whenever they can.[1a]
