I am using
Chaos Space Marine Rules set. Black Legion rules, but my army will be built on Space Marine Models dominately, and it will be a Space Marine chapter, physically, and fluffwise.
My goal is to create a VERY THEMED, and FLUFFY ARMY yet still have EXCELLENT playing.
Now I am trying to build fluff more specifically on the army composition and models, and how it should fit into all of this. Fluff about the chapter will come later once i get this figured out. So I'll be needing suggestions if my stuff sounds right, as I am going to REASON with the 40k system a lot.
Color Scheme :
So far my Basic idea for this chapter will be:
Black Bolters, Black chainsword
Gold Body and legs.
White or Silver Eagle?
Shoulder Pads, Red or black on the bottom trim, and Gold On the top padded part.
::Armoury::
D. Mutations - Servo Arms - Providing the extra attack
D. Str. - Bionical Arm or something to show more str.
D. Flight - Jetpacks
D. Resilience - Heavy Armor
D. Talons - Admantium claws
D. Speed - Bionic Legs/Tread Legs
::HQ:: Chaos lord = Iron Lord (Chapter Master) -
*Now I was about to field the Iron Lord as a MK4 Dreadnought with dual lightning claw arms. But have him be played as a Chaos Lord, meaning he would have wounds on Armor value. Though I've heard some fluff discussion stating that it is totally WRONG to have a Dreadnought lead an army, fluffwise. Is this correct? In sense the Iron lord would not really be dead, he would just be manning a dreadnought-like suit.
::Elites:: Obliterators = 'Juggernought' Terminators =
The Admantium Souls have developed a 'new' design on the Tactical Dreadnought Terminator Armor, an extremely heavy variant of the Terminator which can output a wide variety of weaponry to match any situation given in the battlefield, not to also mention the new use of Admantium to improve the toughness of the armour. But the price of tougher army comes with a cubbersome weight, which the techmarines are still trying to adjust. These 'Juggernought' variant Terminators have been unleashed in the battlefield for occasional testing, as they are still under the early ages of developement, there hasn't been high production of these specialized suits which makes them very rarely used in the Adamantium Souls force organization.
Idea modeling is going to be like this: http://i34.photobucket.com/albums/d1...W/DSCF0010.jpg
Repleace the head, and put a Dreadnought Sarchophogus in its place, and greenstuff all around. They are going to look like Mini Dreadnoughts, then plasticard/greenstuff it up to buff up the armor. But I also have the idea these might look really weird. Its a start..
Possessed = Bionically-Enhanced Marines =
*No Fluff yet*
::Troops:: Nurgle Marines = Adamantium Marines = These are the standard marines of the chapter. they are heavily armed with special MK armour, a more armoured version of the standard power armour.
*Fluff has not been written on this yet*
And so toughness 5 is represent the resilience they pack.
Chaos Space Marine Backpacks, just something to make the squad stick out even more, or not?
Heads= Open-face heads w/ respirators? Or something else?
Shoulder Pads:
Front Armor:
( I choose nurgle, but 1k Sons, having 2 wounds does sound like a variant) I might create two different designs to differentiate the variant MKs. )
Nurglings = Servo-Skulls =
Though the servo-skull is often known for serving the Ordo Inquisitors, the Adamantium Souls have adopted these mechanisms and used them for their own. They are the most 'common' constructs seen amongst the assembly line. Being very cheap, easy and simple, these constructs are mass-produced on forgeworlds and given anti-grav motorization to move about. Modified and equipped for war, these servo skulls contain tiny lethal injection needles, laser cutters, and other tandems to engage those who stand in the way. Being driven by a specialized Machine Spirit, the servo skulls are able to function and react on their own, but occassionally has some technical breakdowns.
Each 40mm base will contain a group of servo skulls Daemon packs = Combat Servitors =
Though I'm just not totally sure how I would fit the summoning ideal into this kind of fluff.. maybe worshipping the Machine Gods? And send forth these crazy cc guys? fluff will need help on.
::Heavy Support:: Defilers ='__no name__' Class Dreadnought =
Another 'test' Design variant sent in by the Adeptus Mechanicus. It was originally suppose to be given onto the Mentors chapter for weaponry testing but the Admantium Souls have taken the testing privledges onto their own selves. This new design, adapts the build of the current Dreadnought Chassis, and creating a Heavier class than its predecessor. By equipping it with a wider and stronger arsenal, the '____' Class Dreadnought only be closely matched by its cousins, the 'Juggernaught' Terminators. To balance between heavy equipment and speed, more legs were given, and including an upgraded hull and driven by the Machine Spirit which protects and aids the 'Ancient' driver to prevent it from being disrupted, stunned, or disabled. All contributions essentially creating the Dreadnought into a Pseudo-Walker-Warmachine.
Need a name~ And I'll model this something like.. 
I was wondering of partly copying the design of that, except not putting anything Chaos Like onto it. Then added a battlecannon, and a few guns to it. Any other vehicles will be fitted with 'Extra armour' to represent even stronger vehicular wargear, and to help if mutated hull was to ever be used.
This is my idea on a simple stretch... any comments hah? Or think I'm crazy?
