Suggestions asked for a WH40K campaign

Mods created in the Warhammer 40K universe:
If your mod contains *any* elements from the Warhammer 40,000 universe, it must contain *only* elements from that universe.
You must include a disclaimer in your mod stating something similiar to the following: "This mod is completely unofficial and in no way endorsed by Games Workshop Limited."

Please make the origins of the intellectual property very clear, in other words, make sure that from a brief review of your material people know that you are unofficially using Games Workshop's intellectual property.

More information regarding Games Workshop's IP can be found here: Link. It is strongly suggested that you check it out thoroughly before releasing your mod to the public, and apply it retroactively immediately if you have already released a mod without these features..

Wow, this is serious. Thanks for letting me know. I'll make sure nobody mistakes this for the genuine stuff. I only intend to put things in the campaign that fit within all the established rules and background, but as for the appearence of certain units I need to make small adjustments (i.e I'll use WC3 orc models because I can't model and making super beefy Orks with no fore-heads and huge jaws would be beyond me).

After some thought I've decided to forget about the campaign and focus instead on 1 or 2 free-standing maps just to see how it would work. Rather foolhardy of me to think about creating an entire campaign
