The Fourth Horseman

"It's not a holdout weapon, it's a pathfinder."

- Weapon Description

The Fourth Horseman is a fully automatic Exotic Shotgun in Destiny introduced in The Dark Below as a PS4 exclusive weapon. The Fourth Horseman is available in The Taken King, and is also available in Rise of Iron. In Destiny 2, it is available to obtain during Season of the Worthy from the Banshee-44 quest "In Rides A Pale Horse".

Design Details
"One look at The 4th Horseman, and the care taken in crafting it, points to the old trophy-driven traditions of the hunt, but this blunt force destroyer wasn’t built for just any game. Its precision tuning allows for full-auto firing, while measured impact timing provides an extra kick at the tail end of each magazine—a needed fail safe designed specifically for the weapon’s intended prey, the biggest game in the system, the Cabal."

- Grimoire description

Destiny
This weapon's signature ability is "Thunderer", which grants full auto-fire without needing to upgrade the weapon. It is the fastest firing shotgun in the game, outpacing even Invective, which also is fully automatic. This blindingly fast fire rate allows the player to deal massive damage in a short period of time. However, its limited magazine of 5 rounds hinders its burst damage capabilities until it can later be upgraded with "Return to Sender", which allows kills to replenish ammo directly to its magazine.

Destiny 2
The Fourth Horseman retains the same intrinsic perks as its Destiny 1 iteration, but with the perk "Broadside" (each successive bullet in the magazine increases damage per bullet as well as pellet spread) added in place of Final Round. It is the reigning champion for shotgun DPS due to its full-auto perks as well as the synergy between the Broadside perk and the weapon catalyst.

Lore
"There's a reason the Cabal want to take this weapon from us.

"When you hold the Fourth Horseman in your hands, you bring the storm. You instill fear by commanding the thunder and firing off rounds with lightning speed. Tear through your enemies like light piercing through clouds after the rain subsides.

"You are a force of nature. Unstoppable. Unpredictable. Undeniable.

"Don't forget what the Fourth Horseman brings, after all."

—Commander Zavala

Tactics
The Fourth Horseman was designed to quickly take down enemies at close range. If used correctly, it is capable of downing majors and more powerful enemies such as champions very fast. This weapon requires some skill to get used to the recoil pattern but once mastered, it can deal some of the highest burst DPS in the game in both Destiny and Destiny 2.

Campaign
In PVE, the weapon is great for dealing large amounts of close-range damage in a short time, a useful trait against tanky enemies, especially bosses that sit in one place. If not careful, you may wind up firing more shots than intended, leading to wasted ammo. The low stability often causes shots to miss or only graze enemies if the user is not close enough.

Multiplayer
In PVP, the full-auto trait can be a burden if you don't know what you're doing. Because you only have a limited amount of special ammo to begin with, and the fact that getting more isn't always easy, conserving it is important. The aforementioned traits make for easy kills at close range, but can cause you to use up ammo too quickly, depriving you of a weapon until more special ammo can be gathered.
