The Macharius Omega is a variant of the Macharius Heavy Tank used by the Imperial Guard. The Macharius Omega differs from the standard Macharius tank and its other variants due to its unique main weapon. The Macharius Omega is a war-machine built with a single purpose, the battlefield deployment of the Omega Pattern Plasma Blastgun.
This is the Forge World Macharius Omega on display at Warhammer World.
This weapon is a variant of the common Ryza Pattern Plasma Blastgun commonly deployed on the Stormblade super-heavy tank. The Omega Pattern is smaller and lighter than the Ryza Pattern, as it uses a compact generator and smaller force crucible allowing it to be mounted on smaller armoured hulls, such as the Macharius. The downside of this version of the Plasma Blastgun is that it is less stable and generates considerably more heat than the Ryza Pattern, but fortunately it is also much easier to manufacture.
While the sins of innovation and initiative are frowned upon by the Adeptus Mechanicus, new patterns and designs of weapons and armoured vehicles are still created. The Macharius Omega is one such vehicle, created with a single focus, that of the battlefield deployment of the Omega Pattern Plasma Blastgun. The STC for this weapon was originally discovered by Explorator-Magus Hum’nal in late M39, but a Mechanicus schism over the purity and completeness of its template delayed the testing and eventual deployment of the Omega pattern weapon for centuries.
