If anyone is interested I have written a blog on the 40k in a Flash campaign I have been running at my store with some updated rules and territories. Check it out on my -> Blog <- or on the forum that I keep track of it for our local club (link is in the blog). The club forum post has the full rules.
Some of the rules are as follows...
Army starts at 500 points
You must have at least 1 troop choice
You may take up to 1 HQ
You can spend up to 50 points on wargear
No model can have more than 3 wounds
No 2+ saves
No model can have more then 3 wounds
No vehicles with a total points value over 200
Let me know what you guys think.
