How do?

So I'm still all over excited at the long overdue return of Warhammer Quest, even if it's still missing the full on Roleplay experience (you know the one. You walk into a dungeon, chin, hoof, knack and bray three Bloodthirsters, nab all the loot, then get horribly murderified down a dark alley by some oik once you hit town).

And it's got me to thinking - has anyone ever come across a decent 40k adaptation?

I don't mean 'Space Hulk with XP' stuff, I'm meaning 'me and my three mates, for reasons best known to ourselves, are off to raid this derelict/dead world/archaeotech horde'.

See, I've got Calth. And I've got Deathwatch. And I've got Spacehulk.....which means I've got a load of dungeonesque tiles at my disposal - and I feel they're going to waste just being for those three games (ooh, need to pick up the Assassin one as well, why not!)

So yeah. If anyone can point me in the right direction, before I give in and have to track down the old Quest books to come up with my own adaptation
