It's like neither, aside from the fact that there are orks and space marines. There is no traditional resource managment, as it doesn't make sense in the Warhammer universe to have these highly trained killing machines be collecting pine cones 30 feet behind the front line. Instead, you gain resources by controlling territory, much like Battlefield 1942. You must go out and capture land, and the more bases you control the more units you can purchase. A
very scary gameplay idea for paranoid turtlers like me.
Also, there's the concept of morale. If your units are making kills they'll get all jacked up and go on rampages. Conversly if you're being pummelled, you will will be broken and your units will turn into limp wristed little sissies.
