really great add-on/stand alone.
depending on your ideal strat you could max out your lords health and then invade every honor gaurd map to max that out as well or jump them inplace of planet bonuses, so its really quite the enjoyable elemant that winter assault was missing and its replayable which makes it even better.
only draw backs i could find with dark crusade was that some of the lord upgrades dont carry over in to the multiplayer. the chaos lords demon status does but not on the lord him self you have to pay out rec to research it and the greater demon.
as well in the camp. the bloodravens lord is able to equip a teleport generator on his back but not in the multi player. same with the necron lord he doesnt get the decloaking mask. he has the mesh/texture but not the ablitly.
but besides that its still a great addon or stand alone depending on how long you have played DoW. it does service to the table top which is really all that matters. great game and great clone of a greater table top game.
only thing left is to wait for relic and thq to bring out the next addon. hopefully it will have dark eldar and maybe dare i say the hive mind if they can get the game coding to support the nids good enough.
