Depending on the source, this reaction is described as being emitted either as a blinding flash of pure radiant energy, a bright beam of light or simply an invisible beam of intense heat. Targets caught in the beam of a Multi-Melta are simply reduced to charred lumps of steaming, bloody flesh or, if they are armoured vehicles, to melted heaps of ceramite and metal. No form of armour can offer protection from the sheer heat of a Melta Weapon and so a Multi-Melta is especially useful against heavily armoured units, as they melt the target from within the vehicle's hull. Multi-Meltas appear to be composed of an assembly of two Meltagun projectors firing in synchronisation to generate a single beam. Because of its greater power, a Multi-Melta has a longer effective range than a normal Meltagun
