Gigaforts

Gigaforts are a special class of Vannai construct encountered almost exclusively in the China theater. In their present form they bare no meaningful relation to the suits, but because of their shared origin, Gigaforts remain classified as a unique weight class of suit. Interestingly, because they are suits, every Gigafort was also once a human being.

Suit weight classes are generally categorized as Mesh through Medium being within the range of human height, Heavies being between 2 to 5 meters tall, and Fortresses being anywhere from 6 to 20 meters tall. Beyond this, Superforts have been encountered exceeding 20 meters, with specimens approaching 100 meters in height. Gigaforts surpass even this, with their astounding size being comparable to small cities or terrain features. The best documented Gigafort, the Fortress of Giants, was 600 meters tall and 2400 meters across, while Oni Island was, as the name implies, initially mistaken as a sea-bound mountain crag.

The current theory is that Gigaforts started out as standard Fortress-class suits that accumulated resources, "growing" like a living creature from Fortress, to Superfort, to the monstrous Gigafort class. This theory is based on the fact that no Gigaforts were reported until years after the Human-Vannai War began, as well as the behavior patters of the Fortress of Giants actively "feeding" on the land and using the materials for production. Oni Island may have grown in the same manner by absorbing sea wrecks.

The sheer size and array of weaponry alone means that Gigaforts control the battlefield for dozens of kilometers around them. Gigaforts possess the means to deploy endless amounts of drone units in addition to their own armaments, up to and including having the capability to produce suits. Defensively they are protected by missile interception systems and energy fields with seemingly limitless capacity that can be deployed at a moments notice, and should these fail, the attacker would simply slam into meters-thick armor that can quickly be repaired from inside out by internal repair drones.

Gigaforts are immune to any and all hacking attempts. While at first this was attributed to control being handled by primitive "clockwork" systems, it has since been determined that Gigaforts quite contrarily utilize a form of processing well beyond human understanding. While hacking into a Vannai construct or suit can be done by any suit, cyberbrain, AI or computer capable of understanding Vannai programming language and software architecture, Gigaforts utilize Vannai Pocket Dimension technology to house their control method in a completely separate dimension contained inside the Gigafort's impenetrable hull. Gigaforts may therefor not only potentially possess infinite processing power - they might not perform their computational processing in a method understandable by mathematics at all.

While Gigaforts may be formidable, they are not without countermeasure. Exceptional size means exceptional slowness, and the warbands of China were able to survive in spite of the massive killer-machines for years due to their predictable movement patters and pace. Gigaforts also share the same inherent reliance on sunlight for at least part of their energy due to their presumably Sludge-based powersource.

Gigaforts have also be destroyed before, despite their unassailability, though the incredible machines are beyond the ability of anyone one suit or team of suits to take down and require the deployment of strategic weapons instead. The Fortress of Giants, in a plan devised by Armor Corps Lieutenant Liam Lykken and executed by Lt. Anna Graham as Operation Dead Man's Fist, involved transporting an S-Bomb by hand through the Gigafort's layered defenses.
