M112-Raptor
The Raptor is a human version of a turian weapon developed for a conflict on the low-gravity world of Amar. Fighting at longer ranges than they had expected, the turians optimized a low-recoil, semi-automatic rifle with a scope and issued it to their regular infantry, creating a hybrid weapon that was half assault rifle and half sniper. Cerberus Centurions use a version with an underslung grenade launcher, usually equipped with smoke grenades to conceal their movement.
Assault rifle/sniper rifle hybrid with semi-automatic fire and low recoil.
Javelin
Called the Javelin by Alliance marines, this geth weapon holds a reservoir of ferrofluid, magnetically drawn into the firing chamber and expelled at lethal speeds. Like a high-pressure water-jet, the ferrofluid cuts through nearly anything it hits, causing terrible wounds and so much heat that its jet resembles a beam of light. A complex system optimizing repulsion power is visually displayed as the Reticule Sine Cadence; firing in time with the sine wave can increase damage dramatically.
A geth sniper rifle with thermal imaging that allows shooting through walls.
Havoc
A mass-accelerator heavy weapon, the Havoc projects large, concentrated bursts of kinetic energy that slam into groups of enemies, flinging them across the battlefield. Recently created by the Alliance, this experimental gun is popular with resistance forces on Earth: the Havoc's burst effect means a single soldier can fend off entire crowds with judiciously-timed shots.
Valkyrie
After the carnage of the Battle of the Citadel, Alliance officers commissioned an upgraded rifle for their ground forces. Improving on the popular Avenger design, the Valkyrie is now standard issue for new recruits. Exceptionally well-crafted, accurate, and packing ample firepower, the rifle is a hot black-market item on the rare occasion it surfaces
Argus
The Argus is a high-powered rifle favored by senior C-Sec officers. Its accuracy allows them to control the battlefield with deadly precision, and firing bursts ensures ammunition conservation during lengthy conflicts. Other law-enforcement agencies across the galaxy are adopting the Carbine as their standard rifle, as much for its intimidation factor as its suppression power.
Hurricane
While some militaries pass up the Hurricane because of a slow firing rate, the Alliance finds this compact SMG's burst-fire capabilities offer flexible battle tactics. With pistol-like accuracy, a well-placed 3-round burst from the Hurricane chews through shields, armor, and flesh at an alarming rate. Alliance officers were so pleased with field results that the Hurricane is now many squadrons' standard-issue SMG.
Raider
Carried by the batarian military's notorious Special Intervention Unit, the Raider is a semi-automatic shotgun that fires rapidly at medium range. Rather than eliminating recoil, the Raider's integral compensators make it predictable and vertical. Its adjustable choke allows for effortless switching between tight and broad shot-grouping, making it extremely versatile.
Crusader
Bruised and bloody Alliance marines on Torfan attributed their survival against waves of batarian mercenaries to the sheer stopping power of the Crusader. With a design patterned on riot shotguns, this durable weapon has a moderate rate of fire, high damage rate, and tight pellet spread. As its accuracy allows little room for error, the Crusader is primarily found among highly trained soldiers.
Indra
Reverse-engineered from the Cerberus Arc Projector, the Indra is a prototype sniper-rifle that fires a path of ionized air, then electrifies targets with a bolt of lightning-like energy. The Indra maximizes its damage by first piercing its targets with a high-powered shot, and electrifying them second.
N7 Sniper Rifle: Valiant
The Valiant is a high-powered sniper rifle tested by Alliance soldiers during a series of harsh survival exercises on the planet Kruljaven. A redesign of the M-96 Mattock, this streamlined weapon employs a sophisticated fire-control system that improves accuracy by stabilizing the barrel during targeting. While this comes at a cost of reduced capacity and rate of fire, most soldiers find the increase in precision and lethality to more than make up for the tradeoff.
N7 Eagle
When the Alliance's Offensive Handgun Project received funding to update one of designs, its engineers chose to upgrade the already-impressive Phalanx pistol. Like its predecessor, the Eagle is a compact, semi-automatic hand-cannon that delivers unprecedented accuracy and punch with a fast firing rate. The Eagle is named after the Desert Eagle, a classic handgun which has gained a romantic reputation among gun collectors thanks to its popularity in 20-21st century Earth action movies.
Powerful, accurate handgun. Upgrade of the Phalanx heavy pistol.
Arc Pistol
An innovation of Admiral Daro'Xen, the Arc Pistol is a scaled-down Arc Projector that has had its power problems solved so it only requires thermal clips. The Arc Pistol uses a nonvisible laser to ionize the air and create a path for a high-ampere electric shock. It can be charged up for a more damaging blast.
An electrical weapon that can be charged up for a more damaging blast.
M-358 Talon
The Talon is a close-range pistol favored by Cerberus Guardians. Firing heavy-gauge shotgun pellets, it delivers massive trauma to unarmored targets. Its waste heat is punishing enough that it carries six separate ammunition blocks that rotate like a twentieth-century revolver to prevent any chance of shaver jam or misfire due to premature melting of the shot.
Shotgun-pistol hybrid with damage boost at close ranges.
M-237S Hornet SMG
The Hornet is a longer-range submachine gun, featuring an integral laser sight and a sound suppressor for covert operations. Its relatively low rate of fire is its tradeoff for high stability, allowing Cerberus troopers to place shots with little fear of recoil.
Scorpion Defensive Ordnance Pistol
Originally issued to the salarian STG to allow small units to contain much larger forces, the Scorpion pistol now sees service galaxy-wide. It fires low-velocity, squash-head projectiles with dual uses. The high-explosive filler within the projectiles contains an adhesive that sticks the projectile to the target during impact. An infrared signal can then be fired from the pistol with the touch of a button, detonating the explosive instantly or arming its motion detectors, turning the projectile into a proximity mine.
Fires adhesive explosives for use as a firearm or proximity mine.
Unnamed Reaper LMG
Reaper Plasma based Semi-Automatic Assault Rifle. It has a high Re-fire, high damage output and very high recoil because of its size. A unique bayonetta like apparatus allows the weapon to be used at close range.
Disciple
Originally hand-crafted by asari Justicars for their own exclusive use, schematics for the Disciple shotgun were passed down to asari commandos after centuries of negotiation with their order. The Disciple uses shotgun shells packed with micro-scale sub-munitions to deal staggering amounts of close-range damage. Its eezo-powered core can also generate a mobile kinetic barrier, though this quickly depletes the heat sinks that soak up the shotgun's electrical discharge.
Geth Spitfire
The Spitfire is the Alliance's name for a geth minigun of devastating firepower. Similar to their so-called "plasma shotgun," the Spitfire fires charged superconducting toroids that rupture on impact, arcing electricity and flash-converting to plasma. Electrical shock, fragments, and burn trauma then destroy shields and flesh alike. Rotating barrels help cool the weapon, allowing for sustained fire.
Full-auto weapon firing a hail of rounds that produce plasma on impact.
