Meltagun - Known Meltagun Patterns: Accatran Pattern Mark VIII Meltagun - A commonly used Meltagun pattern manufactured by the Accatran Forge World and utilised by the Imperial Guard regiments of the Elysian Drop Troops.Conflagration Pattern Meltagun - Crafted in very limited numbers by Enthor Calibos, a Techmarine of the Salamanders Chapter of Space Marines garrisoned aboard Watch Fortress Erioch in the Jericho Reach, these compact, high-output Meltaguns have gained favour among those Battle-Brothers of the Deathwatch lucky enough to have wielded them. Reflecting the fine workmanship and deep love for cleansing flame of their creator, these powerful weapons have higher penetration and damage output than other Meltaguns at the expense of higher energy consumption.Forgebite Pattern Meltagun - Similar in function to the Vulkan Pattern, the Forgebite Pattern Meltagun is a common variant utilised exclusively by the Astartes of the Space Wolves Chapter.Mars and Mezoa Pattern Meltaguns - As Meltaguns are less prone to failure than Plasma Guns and work best at shorter ranges, they are also prized by raiders and corsairs where close-in fighting and boarding actions are often the norm. The Meltagun is an ideal weapon for cutting through bulkheads or armour. Most use a built-in fuel canister like the Mars Pattern Meltagun, but the Mezoa Pattern Meltagun that uses a backpack to hold the hydrogen fuel is also common.Traitor Legion Meltagun - The Chaos Space Marines make good use of Meltaguns, though they favour a larger version of the weapon dating from the time of the Horus Heresy that can unleash a more powerful heat beam upon a target, dealing greater damage.Ultima Pattern Meltagun - Another common variant of the Meltagun, the Ultima pattern Meltagun is similar in design to a Vulkan Pattern Meltagun. This particular variant has earned the nickname "Tank Killer" for its effective use against smaller armoured personnel carriers.Vulkan Pattern Meltagun  - Meltaguns are the most common form of Melta Weapon and are found in use by many Imperial forces. They are less prone to catastrophic failure than Plasma Guns and work best at shorter ranges. An ideal weapon for cutting through bulkheads or armour, the elite Space Marines of the Deathwatch have proven to have no end of uses for it. The Vulkan Pattern Melta Gun used by the Deathwatch uses a built-in fuel canister, but versions with a backpack attachment are also common.Zepherus Mark I “Beamer” Meltagun - The Beamer model of Meltagun was an attempt to create a longer-range Melta Weapon that was still light enough to be easily carried into combat. Using fragments of decaying scrolls describing several ancient design patterns (and after much divination and prayer) the Zepherus pattern was developed. Though it still uses specialized gases melded and ignited into a sub-molecular thermal state, this weapon features a longer barrel with a radiation beam surrounding the gaseous discharge. This low-level radiations acts as a harmonic wavefront for the super-hot release, allowing it to strike at longer distances. The necessary tuning for the beam to match the discharge proved impractical in the field, however, and only those willing (or able) to spend many hours of difficult correction after prolonged use still stand by the weapon. Almost no fighting units still utilise them despite the superior range, and their manufacture ceased after the first production run. Now prized as trophy weapons, some still see use as part of elite mercenary groups or Inquisitorial Kill-teams.
