ABOUT
Welcome little ’umie to Da Kustom Codex!
Here, you’ll find unofficial rules for Warhammer 40000 & Warhammer Fantasy, along with a few glorious relics from the past, such as Gorkamorka & Mordheim – and, of course, my beloved Horus Heresy…because 30k beats 40k! Basically, everything that ruined the galaxy (and my teenage years), but is now ready to explode like da biggest (kustom) WAAAGH ever!
Ever wondered about smashing Bad Moonz and Evil Sunz together into one unstoppable clan? What would have happened if the Twin-Tailed Comet hadn’t crashed on Mordheim, but instead landed on the Dragon Isles? The Sky Titans don’t have their own rules…did the Ogres in the Old World eat them, perhaps? But most importantly, WHY in Necromunda can’t we move on hexes instead of inches?! If the Warp keeps whispering all this to you too…you’re in da right place!
All in da Kustom Codex with expansions, alternative rules, new units, custom lore and much more still to homebrew – all created with brutal kunnin’ love and even kunnin’ brutal love for the original setting…but with just the right amount of psionic madness. So sharpen your CHOPPA, load up your SHOOTA and play across sacred Terra with da fan-made scraps of Da Kustom Codex!
Brushsmiths & Green-Stuff-Artisans
The gathering of painters and sculptors! Their creations keep this site alive (and looking good). Behind every warband or army, every hired gun or hired sword, every imperial/chaotic/xeno scum, the skills of these “Brushsmiths & Green-Stuff Artisans” help the Kustom Codex turn bits into stories, miniatures into legends and simple ideas into full-blown sagas.
Our collaboration (and friendship) began back when the C’tan still devoured stars like Sunday brunch. The goal of this project is to use (or shamelessly steal) his amazing conversions as a base to unleash new rules or, sometimes, to give life to my most chaotic homebrew ideas. Anything goes! Half the time, I don’t even ask…if it looks cool, it’s going in the Kustom Codex. Make sure to follow his work as a kitbashin visionary & green stuff junkie, and brace yourselves for a showcase of one-of-a-kind creations. No matter what he says, he holds the world record for first-ever conversions of a whole krumpin’ bunch of legendary miniatures.
Dear GW, I need Oldhammer lead, not AoS plastic…
Fabio_Morghot Showcase
The twin brother of the Oldhammer devotee Fabio_Morghot, although “some voices” say he’s nothing more than a psychic echo in a luchador mask. Lore-wise? Yeah, Ahrimask is basically the Omegon of this (kustom) project…the shadow-kin slumbering between airbrush sorcery and a thousand unpainted sons, banned conversions and the sweet curse of procrastination. With great painting power comes great excuses! Indeed, his Quenelles cavalry has been in “work in progress” for over a decade and the Questing Knights have now turned into Black Knights…undead by natural causes. Oh btw, worth the wait!
