Warhammer have embraced the idea of a campaign map with provinces to conquer and other races to fight free from the confines of a story line.
Plays Space Marines, Chaos Marines, Imperial Guard, Tau, Necrons, Eldar and Orks etc.
Great fun, some provinces can boost your chances against the enemy whilst having plenty of resource amount lets you recruit more troops to start with.
Can be fiendishly difficult in some mission but makes you think a little more. There have been times when you need to defend in order to attack so make use of Heavy Bolter Cannons.
