Depending on your army, you should rely on your monsters/cavalry, guns/monsters or constructs. You should almost never rely solely on your heroes, lords or infantry as undead. Weakest magic of all the undead.ДЇurthermore, who are you fighting? ThereвЂ™s a huge difference between fighting, say, wood elves and Dwarves.Д®dit: since you specifically asked about composition - that depends on your faction, your enemy and your play style. The constructs are frightening though and can pack a punch. Cheap infantry but few elite infantry - cheap ranged able to do a lot compared to their price but still bad. In many ways they are the jack of all trades, masters of none. They have a good selection of cheap infantry and chariots and many constructs to deal with any enemy. They are the middle between Vampire Counts and Vampire Coast. If you want to surprise your opponent you can take minimal ranged and just be a slow moving tank of zombies and monsters - you will have no mobility but good damage and great health.ДЇinally, the Tomb Kings. Try to keep your ranged units apart - they wonвЂ™t all stop firing if one gets intercepted then. Use your special monsters to deal with threats or cause chaos among the enemy.

The gist is to delay the enemy as long as possible, buying time for your many guns to decimate them. Their approach is a little more complicated than Vampire Counts. They have cheap tarpit infantry, great selection of ranged and artillery, many unique and useful monsters and strong magic. They are all about being defensive and using superior firepower to win. Vampire Coast is the complete opposite of Vampire Counts. Back them up with Corpse Carts of Morris Engines and they can deal a lot of damage and last a long time. Occasionally you can focus on a heavier infantry core of grave guard. Supplement your army with powerful magic or deal heavy damage upon the enemy. Neutralise enemy mobile units (such as cavalry) with your own mobile units. Their approach is pretty straightforward - use your infantry to lock as much as the enemy in place as you can and hold them while your monsters and cavalry hit all the soft spots. The Vampire Counts are all about being aggressive - cheap tarpit infantry, lost of great mounted units and good selection of monsters. The undead are mostly the simpler factions to play IMO, but they are rather vastly different from each other.
