Dreadnought - Ferrum Infernus Dreadnought: Chaos Ferrum Infernus Dreadnoughts are Dreadnoughts that belong to the various Traitor Legion and Renegade Space Marine Chapters. They are very similar to their Loyalist Castraferrum Pattern counterparts but have not undergone the mutational process to become Helbrutes.Like their Loyalist counterparts, the body of a mortally wounded but feared Heretic Astartes of a Renegade or Traitor Legion warband is placed within a cybernetic sarcophagus that contains multiple life support technologies. This sarcophagus is then placed within the armoured form of a combat walker that the sarcophagus' inhabitant can control using neural impulses.However, most Chaos Space Marines, unlike their Loyalist counterparts, do not see this fate as an honour but as a destiny to be avoided at all costs. This is because being trapped within the armoured shell of a Dreadnought while suffused with the power of Chaos drives the Chaos Space Marine insane and transforms the resulting Ferrum Infernus Dreadnought into an unstoppable and incredibly blood-thirsty killing machine.As a result, far from being revered for their wisdom or experience like their Imperial counterparts, all Chaos Dreadnoughts are shackled securely when not in combat because the crippled Chaos Space Marine within has been driven insane by millennia of being trapped within the cold cybernetic sarcophagus as the power of Chaos warped his mind and spirit. They are used as insane behemoths to trample the enemy and are regarded with caution, as the madman within the Dreadnought can turn his wrath upon his comrades if there are no enemy units within range.It is exactly this unreliability that led Abaddon the Despoiler to call for the creation of the Defiler as a replacement for the Traitor Legions' Dreadnoughts. Chaos Dreadnoughts' weapons are configured in the same way as Imperial Dreadnoughts of the same pattern and variant but have no specific designations.As they are not wise or even reliable by any standard, Chaos Dreadnoughts are usually designated as fire support or frontal close combat assault units rather than elite warriors like their Loyalist Space Marine counterparts. Chaos Dreadnoughts could also once be configured into more powerful versions of their Imperial counterparts by the use of special Marks dedicated to one of the Chaos Gods, imbuing them with unholy sorcerous powers. This practice is now rarely seen amongst the warbands of Heretic Astartes that serve the Dark Gods.Chaos Dreadnoughts are armed similarly to their Loyalist counterparts with potent ranged and close combat weapons. These include Dreadnought Close Combat Weapons such as claws or energy-infused whips and flails, or twin-linked Autocannons, Lascannons and Heavy Bolters. Chaos Dreadnoughts are also sometimes outfitted with a Multi-melta or a Plasma Cannon to provide enhanced armour-piercing abilities.A Chaos Dreadnought's close combat weapons often have a built-in Bolter or Heavy Flamer and one or both arms can be replaced with a Missile Launcher to provide added ranged fire support. Chaos Dreadnoughts often prove erratic or unstable in combat and as a result few Chaos Space Marine warbands will make use of them unless there is little other choice and will prefer to unleash other, more reliable daemon engines upon their foes.
