Background
Twisted, evil parodies of their mountain-dwelling brethren. The Abyssal Dwarfs make use of slaves to bolster their numbers, and dark technologies to rain fire and destruction on their foes. When the hordes of Tragar march forth, the world trembles before them. The ground shudders under the march of thousands of slaves and soldiers, and the air shivers with the sound of arcane weaponry and dark sorcery.
How do they play?
The Abyssal Dwarfs are the wicked and malevolent take on their dwarf cousins. The core units are comparable with the dwarfs and are as slow moving, but players have access to the winged nuisances that are gargoyles and also fast-moving cavalry in the form of Abyssal Halfbreeds (part dwarf, part�?� thing). The army has a different take on black-powder weaponry, favouring mortars and blast weaponry over more direct cannon fire. The impressive golems can form an implacable line to provide solidity and stopping power. Units in the army are typically Vicious, which means they re-roll 1s when wounding a unit. Nasty stuff!
What�?Ts in the army?
Blacksouls, Immortal Guard and Decimators shape the army core and make for a typically stubborn dwarvern battle line. The Decimators are deadly at short range with their Thunderpipes �?" if they can get into position. Abyssal Berserkers and Slave Orc units are slightly faster units that can be a first wave or counter attacking element. Lesser Obsidian Golems, Gargoyles and Abyssal Halfbreeds give the player options on how the army should behave and be themed. A would-be Abyssal Dwarf player is spoilt for choice with three different types of mortar and a flame-thrower to choose from. Heroes are pretty decent with some good hitting power, flying options and magic too.
