Which Codexes are missing?

[job]

Codex Deathwatch, both the other inquisitorial ordos get some love.

I was going to add Deathwatch. That would be so cool. (The hobby shop owner back home in Eugene, was carefully converting Kroot warriors to have parts of different armor and weapons so he could play them as Inquistorial Killteam. It was awesome looking.)

I'm going to throw out another:
"The Fallen" Dark Angels codex

[kojibear]

A codex based on the arachnoid xenos race on planet 'Murder'

I wouldn't mind a Sister's of Battle Codex, too, Underdweller.

Megarachnids? If I remember the book correctly they were confined to that one planet by some high tech race (interex?) and then Horus and Sanguinius slaughtered them. A few could have escaped and spent the last 10000 years rebuilding their population. They had a very Starship Troopers type feel to them, so that is definitely cool and would look fun on the table top.
