The rules are a reasonable £15 for a 152 page A4 full colour rulebook but I think you will also need a card deck for £5 but I'm not sure about that. According to the website the rulebook's contents include:
Core Rules: All the rules you need to play.
Background: Rich and detailed setting for the DzC game universe, as well as in depth background for all four races and their units. You'll be in no doubt as to where you're fighting, why you're fighting and who you're fighting with!
Army Lists: The full stats, lists and special rules for all four races.
Scenarios: A wide selection of scenarios to keep your games fresh!
Colour Schemes: A wide selection of colour schemes and camouflage patterns are showcased for each race, giving you plenty of inspiration when painting your armies! Further hobby tips, articles and information will be made available from our downloads section in the coming weeks.
Guest Painters Pages: Some inspiring work by keen gamers and painters unaffiliated with Hawk Wargames.
As I've said before the models look beautiful but, for me, they're just too expensive. Although some of the army deals are better value you'll still be buying addons at full price.
