This is probably the coolest mod ive seen so far, and it was a wonderful intro to show of the different units marching into battle! Love the design of the underworld gate guardian and the dancing devils of dark omen! at 6:57 i kept going "What is that? WHAT is THAT? WHAT. IS. THAAAT!?" Whatever spider/crab thing it is made me first think of a Jorogumo or a Tsuchigumo, but migth very well be a mixture of things! (According to the steam mod page, it migth just be called the "Pale Lady"? Either way its terrifying!
Visually, the Jade Vamps are wonderfully horrible. The designers clearly looked at those classical Chinese and Japanese illustrations of Buddhist hell.
I always used mods on total warhhamer 2 to make them better. Permanent clan rat summons and more variants of storm vermin etc. They are great for abushes, 1v1 they are a bit poor yeah.
