A classic Tenno sniper rifle, the Vectis is ideal for ranged takedowns.
The Vectis is a high powered, single-shot, breech-loading sniper rifle. Its single shot behavior provides a bolt-action feel. With significantly less zoom compared to other sniper rifles, it is much better suited for the medium range combat that occurs within the game.
Due to the Vectis' single-shot firing mechanism, Heavy Caliber can be equipped with little noticeable effect on its long-range accuracy. Heavy Caliber will affect the trajectory of additional bullets created by Split Chamber however.
The Vectis automatically reloads once the weapon finishes its recoil animation. However pressing the reload key immediately after each shot can start the reload early. With practice, this method can shorten the downtime between shots significantly.
The Vectis shines when used in larger, more open maps where the player can position themselves into spots with a good overview.
The Vectis will have 30 rounds of Max Ammo instead of 72 when the Castanas or the Angstrum are equipped in the secondary-slot. This might be because they both draw from the same sniper ammo pool, and the above weapons have an ammo capacity of 30.
Vectis is one of only two sniper rifles accessible via the Market (the other being the Vulkar).
Despite the fact that this came in last place in the Primary Weapon Content Development poll held in the Design Council, it has come out before the Tigris, which had come in second place (the Soma was the primary weapon that came in first place in that poll).
There is some contention in regards to how the Vectis' action works, but it appears to be classifiable as a breech-loading, single-shot rifle.
The weapon apparently fires caseless rounds.
When reloading, the Tenno appears to insert something (likely a new round) into the receiver of the Vectis. The rear portion of the upper assembly appears to automatically rise after firing. The Tenno will smack this assembly down after loading the round.
The series of hoops along the top of the rifle are a sighting system, but how it works is not obvious, suggesting a sensor and neural link is used to provide zoom.
The Vectis is the first true Tenno-made sniper rifle, the others being made by either the Corpus or the Grineer.
Vectis is Latin for "bolt" in the sense of a heavy tool such as a crowbar or a heavy bar used to shut a door.
