The Cyclops was a Squat vehicle designed in 985.M39. The Squat Cyclops was a massive, juggernaut war machine based on the Colossus chassis, mounting a heavy, destructive weapon known as a Hellfury Cannon. It was designed originally to devastate rival Squat war machines.
The first Cyclops was created by Warlord Harkrund (sometimes known as Harkrund the Insane) of the League of Grindel during a clash with the League of Thor over exploration rights to the newly rediscovered Lost Stronghold of Dargon. The League of Grindel was heavily outnumbered in the ensuing military actions and suffered in particular due to the superior numbers of Leviathan and Colossus war machines employed against them. A high-powered anti-armour weapon was needed, and in a leap of engineering logic, Harkrund ordered that a new experimental starship weapon - the Hellfury Cannon - be mounted onto a Colossus chassis.
The first Cyclops, Harkrund's Fury, was an instant success, annihilating a Colossus and a Leviathan in its first battle. More were constructed, and the League of Grindel took the initiative. However, the League of Thor was able to replicate the design after a few months, leading to the destruction of several strongholds belonging to both Leagues by the fearsome Hellfury cannon.
The Cyclops was designed to be a superior anti-armour or strongpoint-destroying vehicle. The Colossus hull was essentially rebuilt around the Hellfury cannon, and getting this ultimate Titan-killing weapon into position is the main purpose of the vehicle. However, the Cyclops' armament was comprehensively packed out with other varieties of weaponry. Two other forward-fixed guns complement the Hellfury; these powerful Melta Cannons could be deployed against enemy armour that is not worth a Hellfury blast. A rapid-firing Battle Cannon was mounted on a turret atop the vehicle, providing all-round firepower. Six fearsome Doomstorm missiles are racked at the rear of the vehicle, whose plasma warheads can obliterate armour and packed ranks of infantry with ease. And finally, there are several pintle-mounted bolters placed at fighting galleries around the exterior of the vehicles' superstructure.
Such a military investment has a high degree of protection; metres-thick armour plate covers all points of the vehicle, with there being no particularly weaker parts of the armour. 5 banks of void shields are also operated, powered by the immense plasma reactor that is also needed to run the Hellfury cannon. Lastly, the Cyclops possesses a sophisticated fire-control system that allows most weapons to be rapidly fired at the same time even whilst the vehicle is moving.
