Shuriken Catapult
The primary category of Eldar small arms is the Shuriken Catapult. A gun that fires bursts of hypervelocity wraithbone ninja stars.Its actual effectiveness is greatly inconsistent throughout the fluff, depending on the source material. On the tabletop, the Shuriken Catapult is just as effective as a Bolter. It should be noted that, according to the earliest versions of the game, the Shuriken Catapult was available to nearly every army (just like most basic weapons) including Imperials. The weapon works by shaving off a very thin slice off a solid munitions core and accelerate it to lethal speeds (if you have played Mass Effect it's just like that), with a very high rate of fire. It is for this reason Orks respect this weapon, due to the fact that it shoots choppy dakka, and a lot of it. The downside is that it has a lower effectiveness against armor than Bolt weapons. There exist several variations of the Shuriken Catapult.
Shuriken Pistol
As commonly used as the Laspistol by the Imperial Guard, the Shuriken Pistol is the main sidearm for the Eldar war hosts. They are part of the equipment of the Howling Banshees, Striking Scorpions and Storm Guardians, and are used by Farseers and Warlocks as well.
Shuriken Catapult
The Shuriken Catapult is the signature weapon of the Eldar: of light design and sleek curves, carried only by Guardian squads.
Avenger Catapult
An improved version of the Shuriken Catapult and carried by the Dire Avengers, it has a superior range to the regular Catapult.
Shuriken Cannon
The heaviest of the Shuriken weapons, the Shuriken Cannon is a heavy version of the regular Catapult. It has several uses: it can be mounted under jetbikes, onto vehicles, gun platforms and can be carried on foot. Due to its light design it can be fired even when on the move, allowing nearly any unit in the warhost to augment its firepower.
Shrieker Cannon
Used by the Death Jesters, the Shrieker Cannon fires shurikens saturated with violent toxins, causing any target struck to rupture and explode.
Maugetar
The ultimate shuriken weapon is Maugan Ra's famous Maugetar, that doubles as a power scythe, thus making it a choppy shooty choppa, and is able to cut hierophant biotitans in half.
