A Warhammer 40k total conversion for Fallout: New Vegas


The NCR has been totally converted to the Imperium, including imperial guard forces, Adeptus Arbites, deathkorps of krieg, space marines and sisters of battle. The boomers have become elysian drop troopers and gun runners the skitarii


The Legions and bandits have become the Forces of Chaos, including bloodpact, chaos space marines, khorne beserkers and cultists. The deathclaws have also been retextured, so they look more like daemons and the jackal gang are now DarkEldar


The Viper Gang and Great Khans have become the Eldar and Renegade eldar respectively


The Black Mountain supermutants have been converted to ORKS


The brotherhood of steel have become the Soul Drinkers


Many of the wild beasts that roam the wasteland such as mole rats, bloatflies and ants have been converted into Tyranids, hermaguants or termagaunts


Random patrols of tau have been added, as well as an addon which converts BOS to tau.


This mod Features a number of customisation options such as choosing the space marine chapter/chaos space marine legion that is used during the mod. However the new space marine customisation addition to the mod allows users to mix and match shoulder pads, gloves, backpacks, arms, legs, etc. Each piece of the space marine armour can be customised amongst the number of presets already in the mod, which will grow as new chapters/legions are introduced into the mod.

additionally there will be several additional customisation options added to the mod from feedback and other ideas such as replacing cadians with deathkorps of krieg, or changing the brotherhood to tau instead of soul drinkers, and so on. The mod aims to add a great deal of customisation to the mod so that it can best cater to individual user preference

-this means that either you have a corrupt .esm or .esp file-or that you have not put the 'meshes' folder in the right directory

--------funky textures--------
-means textures are missing, probably not in the right directory

Whats up?


sorry I have been away for so long!! I have been super busy with university (college) and did not have time to work on this mod. however during my last break I put together a huge release which completely overhauls the mod in its current state. These preliminary changes are outlined below, but are subject to change or additions. the main release is virtually finished, just needs some polishing. I have also modded the dlc's, however I have not had time to fully test them.

Fallout 4 Warhammer 40k

I know you have all thought about it!

I would really love to , but whether or not I can do it really depends on how easily Bethesda has made it to port weapons and armour over to that game. if they are using a new skeleton for characters or the power armour modding system is complex, it might not be possible. Re-rigging armour to the new skeleton is unfortunately beyond my abilities at the moment.

I will be putting images and videos onto my youtube and I hope to release this version soon but it really depends on my uni (college) workload. until then please feel free to comment what you think, any ideas I can include in the new release and what else I should change.

until then stay tuned! :)

I recently downloaded this mod but when ever I put on the armor in Doc Mitchel's house all that I get is 2 giant error signs. I'm not sure why this is happening, I followed the install video correctly and not sure what is causing this. Any help is greatly appreciated. Thanks!
