This is a supplement to the Warhammer 40K 2nd Edition rules. From the box rear: "This box contains over twenty full colour vehicle datafax including everything from bikes to battle tanks and dreadnoughts. A new deck of vehicle custom cards is also provided to let you individualize and convert your mechanized forces." Due to the nature of Games Workshop revising their game rules, few of these components are usable in the current edition. Box contents include (according to Dark Millenium rule book): - 48-page Dark Millenium Rulebook - 24 Vehicle Data Cards - 60 Psychic Power Cards - 8 each for Orks, Eldar, Librarian, Inquisitor, and Adeptus - 4 each for Slaanesh, Tzeentch, Nurgle, Squat, and Tyranid - 36 Warp Cards - 18 Strategy Cards - 10 Vehicle Cards - 4 Imperial - 2 Ork - 4 General - 9 Counters - 6 Rad markers for Rad Grenades - 1 Traps marker - 1 Virus marker - 1 Slaanesh effect marker - 7 Templates - Da Krunch template - Eldritch Storm/Force Dome - Death Wave - Destructor/Stream of Corruption - The Gate - Hellfire/Machine Curse - Smite/Firestorm of Tzeentch - 55 Wargear Cards - 18 Strategy Cards - 4 Mission Cards
