Cut Halo 5: Guardians weapons

During the development of Halo 5: Guardians, a number of various weapons were concepted and prototyped by 343 Industries for inclusion in the game, though were ultimately cut for various reasons.

Glass cutter
The glass cutter was likely intended to be a support weapon based around the concept of a tool developed for cutting through the glass on Meridian. The weapon was concepted by David Bolton.

Grenade launcher CLUSTER
The Grenade Launcher CLUSTER is an unused REQ weapon that can be found within the files of Halo 5: Forge. The weapon appears to have been fully modelled, textured, and functionally implemented in-game based on the existing Grenade Launcher. It is unknown why it was cut from the game.

Like other M319 grenade launchers, it can be fired immediately or held down to manually detonate on release. Additionally, manual detonation results in an EMP effect. Upon detonation, the projectile will split into 8 separate projectiles dealing damage in an area. Due to the spread and EMP effect, the secondary fire could be useful in disabling air vehicles. The splinters attempt to assemble into the same shape made by splinters of the traditional splinter grenade. Said shape is a plus-shape viewed from one side and a horizontal hexagon viewed perpendicular to that side.

Brute weapons
Files within Halo 5: Guardians show that 343 Industries was planning on releasing some Brute weapons into the Halo 5 sandbox - possibly to coincide with the release of Halo Wars 2. These weapons coincide with a new scope variant planned for inclusion for use on loadout weapons.

Brute sniper rifle
The brute sniper rifle was going to be a weapon in Halo 5: Guardians that would have been a precision sniper rifle that was one of four brute weapons cut. The weapon holds 4 in its magazine, with a reverse of 12 rounds total of 16 rounds. The Blamite Needle fired from the sniper are the same model fired by the Needler though recoloured and made bigger, intended as a placeholder these rounds would explode after a few seconds after hitting the target, the explosion is not massive and likely only to hit the enemy if they stand on it or are impaled. It takes one body shot with explosion to drop spartan shields and another body shot to kill, while if hitting the head it is a one shot. With the sniper having a 3.5 second reload speed could ensure this would've been a deadly sniper if implemented in game.

Brute magnetic missile
The brute magnetic missile was going to be a weapon in Halo 5: Guardians that would have been a rocket launcher that was one of four brute weapons cut. The weapon holds only 1 round in its magazine, with a reserve of 5 total of 6 rounds. The rocket fired from the gun is a shot that splits into five mid flight, which then explode after a few seconds and causes a emp to vehicles on impact. It can completely disable vehicles with one shot, emping the vehicle, and can destroy a vehicle afterwards with the explosions. It only takes one shot to kill a fully shielded spartan. With the launcher having a 5 second reload speed this launcher would've been deadly to vehicles and Spartans if implemented.

Brute spiker
The brute spiker was going to be a weapon in Halo 5: Guardians that would have been like the Spiker though was one of four brute weapons cut. The weapon holds 30 rounds in its magazine, with a reserve of 80 total of 110 rounds. The Blamite needles fired from the Spiker are the same models fired by the Needler, intended as a placeholder to represent the spikes fired from the Spiker. Although using the Needler's ammunition, the Spiker behaves as its Halo 3 version, and has no lock on cabailities. It takes roughly twelve rounds to drop shields while hitting the body, and then six or more for the kill. With the spiker having a 1.5 seconds reload speed made sure this would've been a useful backup pistol.

Brute gatling mortar
The brute gatling mortar was going to be a weapon in Halo 5: Guardians that would have been a massive mortar held like the detachable turret the mortar was one of four brute weapons cut. The weapon holds no rounds and instead has a percentage of its ammo that doesn't run out, this shows that this weapon was partly being implemented, when it was scraped. The projectiles that are fired from the gun are fast firing explosives bolts. It takes only five of these rounds to drop a fully shielded spartan regardless of body shot or not. With no reload speed and its fast fire rate would've made this a deadly weapon if implemented.

Brute scopes
Contained within the files of Halo 5: Forge are scopes of Brute origin. The scopes are compatible with the Battle Rifle and Assault Rifle, and may have been intended to coincide with the 2016-2017 release of Halo Wars 2 - which primarily focused on the Banished as an enemy.

Early Promethean scope
Early builds and concept art show an earlier revision of the Morph sight available for use in the final game.

Test weapons
These weapons can be found within the files of Halo 5: Forge and made functional via modding. They consist of various weapon prototypes tested by 343 Industries but ultimately never implemented.
