Z-130 Suppressor

The Z-130 Directed Energy Automatic Weapon, also called the Suppressor, is a fully automatic Forerunner energy weapon. It is commonly utilized by Promethean Knights.

Design details
The Suppressor was first introduced during the Kradal conflicts. It gained prominence during the human-Forerunner war and the Forerunner-Flood war. The Suppressor is a fully automatic weapon employing a conventional coil set architecture that fires bolts of hard light in rapid succession. Its high rate of fire and efficiency against the Flood led to its widespread use among the Forerunner warriors during the Forerunner-Flood war, particularly when attempting to retake vessels captured by the Flood; however, it is similarly effective against all organic matter. Thousands of years later, the Suppressor's coil set design was reverse-engineered by the Covenant for many of their weapons.

The weapon possesses an angular design and metallic casing. It appears to be held together, at least partly, by energy fields as indicated by its self-assembly process. Orange highlights can be seen while the weapon is self-assembling and throughout the casing once assembly is complete; these highlights grow brighter when the weapon is fired.

Advantages
The Suppressor holds a large ammunition capacity and deals considerable damage at close range, making it even lethal to non-shielded infantry. The Suppressor's high rate of fire is very advantageous in close-quarter situations. Although an individual shot from the Suppressor may do little damage to another player, its high rate of fire grants the weapon the fastest killing speed of all primary loadout weapons. The Suppressor is more efficient against unshielded individuals. Using a precision weapon, such as the M395 DMR, with the Suppressor allows the player to be effective at all distances. When paired with the plasma pistol, the plasma pistol can be used to eliminate an individual's shields, while the Suppressor is used to kill the now-unshielded enemy.

Disadvantages
Despite being the quickest-killing primary loadout weapon when every shot fired hits its target, the Suppressor's various disadvantages make it difficult to achieve this. It has little to no accuracy at medium and long range (even with short controlled bursts) and has a lengthy reload time. The Suppressor is not very efficient against shielded individuals. The bolts fired by the Suppressor move rather slow, requiring the player to be close to enemies or to lead the target. The Suppressor is not efficient at handling multiple shielded players at once, due to relatively low projectile speed and limited damage against shielded targets.
