I'd set it on a planet where a massive Chaos attack took place by Abaddon the despoiler fleet. Or go back to Horus attacking Terra...

This game is perfect for a WH40K conversion. As xqlusive says I too have been waiting for a new WH40K Chaos Gate type game. I also think it would add to sales in a noticeable way if a decent WH40K mod was made. The only issues I see are the research\tech aspect as tech hasn't advanced for 10,000 years and in some cases even reversed. SO that sid eof the game would need to be massively altered in some way. The combat engine mechanics though are as I said perfect.
