God Arc

The God Arc  (神機 Jin-Ki, God Machine) is the main weapon of choice of the characters in the God Eater universe. Like the Aragami, these weapons play an important role in the story and in the gameplay.

Definition
God Arcs are mechanical weapons that are infused with Oracle Cells. In short, the God Arc is actually an Aragami itself, with an artificial man-made core called the Artificial CNS. It is currently the only weapon capable of eradicating the Aragami. The God Arc's strength can be temporarily boosted by devouring an Aragami.

The God Arc is a complex weapon. As it is an Aragami, it is made of Oracle cells, the only thing that can harm them. The first form of God Arc was in the form of a gun that shot converted Oracle Shots. At first, these guns were no bigger than a pistol, due to the cores being converted coming from Aragami the size of small mammals. However, with these pistols, the God Eaters were able to take down bigger Aragami such as Ogretails. In a process similar to natural evolution, the God Arcs then evolved to the size seen today. Next in development was a God Arc made in the shape of a blade. Typically, blades could not harm Aragami due to the bonds between cells being too strong to unbind. However, with God Arc blades, Oracle Cells are lined up along the blade's edge, which allow the blade to cut the bonds and harm the Aragami.

Development of New-Type God Arcs
Flaws were apparent in the two separate types of God Arc. The blade type Arc could collect Oracle cells for conversion, but could not fire them; conversely, the gun type Arcs could fire the shots, but had no means of collecting Oracle cells short of refills carried with the God Eater. This was fixed with the development of New-Type God Arcs. These weapons had the functions of both blade and gun, and could therefore fulfill a much more flexible role as melee and long-range platforms. However, the God Arcs with this function seem to have lower rates of compatibility than others, making Old-Type Arcs still feasible.

Dangers of the God Arc
Being an Aragami, the God Arc still has the urge to devour, and when it is in storage it will start to exhibit such behaviour. It is also completely linked to its compatible God Eater; if a God Arc is wielded by a non-compatible God Eater, its Oracle cells will begin to devour them. This is a fact without a single exception. However if another God Eater is found to be compatible then the Oracle cells will not devour them. There has been only one case where a God Eater has been found to be compatible with two God Arcs, Livie Collete is the first God Eater who has been able to use another God Eater's God Arc alongside her own, seemingly without any visible consequences. She is capable of wielding the God Arc of Julius Visconti. However, she isn't the first God Eater to use another God Eater's God Arc, the first being Kota Fujiki, wielding Tsubaki's Mousy Blow.

The Protagonist of God Eater learns this the hard way when fighting off a Vajratail in the Fenrir Far East Branch HQ; they recklessly decide to use Lindow's God Arc. This severely injures them, and renders them temporarily comatose. Later, when they use it again, their left arm shows signs of Aragami corruption similar to Lindow's, and they then dual-wield Lindow's God Arc and their own - a unique feat that has never occurred in the past.

A human who suffers Aragami infection from their God Arc is quite hard to kill once they turn full Aragami. The Oracle Cells mutate to form a structure unique to them, and only them. This renders them invulnerable to all weapons except their own former Arc. This means that the Aragami is generally safe from threat, due to the details above. Only once has such an infection occurred, and it was defeated by a similarly improbable event.

Types of God Arcs
There are two types of God Arcs:

Old-Type God Arcs: The previous version of God Arcs, people who wield them are called Old-Type God Eaters. Shows an increased prevalence as compared to New-Types as it has been the staple until now. Unlike the New-Type God Arcs, these God Arcs are unable to transform between Blade Form and Gun form, and thus have less flexibility. In the past, these God Arcs were limited to the Gun form (e.g Pistols). With pioneering research from Fenrir and the success of the first prototype, Soma, the Blade form was later incorporated.

New-Type God Arcs: These are the newest type of God Arcs, and people who wield them are called New-Type God Eaters. People who are compatible with these God Arcs are quite rare. Unlike the Old-Type God Arcs, these God Arcs can freely transform between Blade Form and Gun form. New-Type God Arcs exhibit superior power as compared to Old-Type God Arcs.

Short Blade
A quick but weak weapon that allows for the user to be more versatile and mobile than any other weapon available. It also has the best aerial capabilities, thanks to the rise slash air step feature, which allows the user to potentially perform 2 mid-air combos in quick succession. Best suited for quick or aerial enemies.

Long Blade
The standard and most balanced weapon, type; moderate speed and strength are combined for a weapon suitable for any situation. It also has a quick-fire option to fire off a quick bullet while still in sword form.

Buster Blade
One of the most powerful, but undoubtedly the slowest out of all the weapons, this will apply huge amounts of damage with every successful hit, with a big emphasis on blocking rather than dodging as proven with its secondary attack, which is to parry, then to slash upwards with a powerful strike. Usually best to use for slower Aragami (E.g. Quadriga).

Charge Spear
Another weapon on the speedy side, this weapon has 2 secondary functions: the first being exactly as the name states; to charge. By holding down the attack button, you can charge your spear to thrust forward with and deal massive damage, while on top of that, increasing damage output for the next combo you perform. You can charge the spear while moving, and even sprinting. It can also allow a cancel by performing a backflip, which also functions as a dodge.

Boost Hammer
The other heavy weapon, its defining factor being the ability to continuously unleash a barrage of attacks by holding down the attack button to charge the weapon, then pressing the button repeatedly to execute these deadly attacks, provided you have enough stamina.

Variant Scythe
The Variant Scythe is, as its name implies, a scythe shaped weapon. It is capable of quick combos and has the unique ability to extend and hit any given Aragami multiple times with each movement.

Assault Gun
The only firearm that has rounds which allow the user to move while shooting, though these rounds will be significantly weaker than regular bullets, as they apply little to no damage.

Sniper Gun
A type of firearms designed for maximum long range efficiency and compatibility with laser-type Bullets, being capable of using scopes in order to shoot from afar.

Blast Gun
Blast type firearms are best suited for causing impact damage to an Aragami. They are especially designed so that they are highly proficient at damaging several Aragami at once with their radial and bomb bullets.

Shotgun
A firearm that is best used close up, as the shells created specifically created for this weapon have a wide spread, thus will be the most efficient as short range.
