Weapon Types

Weapon Tiers

Conventional/Ballistic

These are the basic weapons you start with - they are relativity unchanged in Long War Rebalance. You will want to upgrade to superior guns in the long run. Ballistic weapons use the same models as EXALT ballistic weapons in vanilla.

Base Damage: 4

Electric

There are 3 electric weapons: the Arc Rifle, Arc Pistol, and the Stun Rifle. While most campaigns will likely build some of each, the Stun Rifle is mandatory to win the game.

The Arc Rifle and Pistol only deal full damage against Mechanical units, and the Supercapacitors foundry project increases their damage.

Arc Rifle: 7 (vs mech)
Arc Pistol: 4 (vs mech)

Beam Lasers

Early beam lasers form the second tier of weapons, and all carry a small inherent accuracy bonus, which can make them good 'training' weapons for inexperienced troopers. Compared to Long War, Beam Lasers have been overall buffed, retaining increased accuracy but also higher crit and a small boost to mobility.

Base Damage: 4
Bonus Stats: +10 aim, +10 crit, +0.6 mobility
Note: Pistol gains +20 crit (no aim or mobility)

Gauss

Gauss weapons return to ballistic projectiles but elerium power sources make man-portable magnetic accelerators practical; combined with alloy-based projectiles, it's a recipe for pretty formidable personal weaponry.

Gauss weapons have lost their bonus ammo capacity and their ability to ignore enemy DR. Gauss weapons are essentially just a damage upgrade over Ballistic and Beam weapons, however the 'Quenchgun' foundry project will grant all Gauss weapons a +1 damage penetration bonus against all mechanical units, which helps make Gauss weapons more effective against mechanical leaders or bosses.

Furthermore, the Gauss Long Rifle and Alloy Strike Rifle (Now Gauss Strike Rifle) have reverted to function as normal Sniper and Strike rifles. Gauss weapons use the original XCOM ballistic weapon models.

Base Damage: 6

Pulse Lasers

Refining and enhancing laser technology allows for the development of pulse laser weaponry, another step up in terms of firepower. Pulse lasers are simply a refinement on Beam lasers, dealing more damage as a bonus. They use the same visuals as XCOM-built laser weaponry from vanilla.

Base Damage: 6
Bonus Stats: +10 aim, +10 crit, +0.6 mobility
Note: Pistol gains +35 crit (no aim or mobility)

Plasma

Plasma weapons remain the most powerful weapons available to XCOM, and have had their unique bonuses increased. However, Plasma weapons now have a significant meld cost and require UFO power sources in their construction, they also take longer to research. However, you no longer need to capture Aliens and recover their weapons in order to manufacture Plasma weapons.

Base Damage: 8

Plasma-Specific Bonuses:

  • Plasma Rifle: Grants Biological Shredder
  • Plasma Battle Rifle: Grants Mechanical Shredder
  • Plasma Carbine: +10 defense (+15 defense total)
  • Plasma SMG: +1.3 mobility (+2.0 mobility total)
  • Plasma Reflex Cannon (Shotgun): +2 damage against targets within 4 tiles
  • Plasma Strike Rifle: +3 damage against uncovered targets
  • Plasma Sniper Rifle: +2 damage against targets at Squadsight range
  • Plasma Novagun (SAW): +3 penetration against Mechanical
  • Plasma Dragon (LMG): +2 damage to Suppressive Fire
  • Plasma Particle Cannon (MEC): +4 damage against Mechanical
  • Plasma Autocannon (SHIV): +15 aim, +15 crit

Weapon Classes

Several classes of weapons occur at each technology level. The weapon classes are, in descending order of base damage:

Weapon Base Damage
LMGs and SHIV/MEC Weapons 200%
SAWs, Sniper Rifles, Shotguns, and Rocket Launchers 150%
Battle Rifles and Strike Rifles 125%
Assault Rifles 100%
Pistols, Machine Pistols, Carbines, and SMGs 75%

Primary Weapons

Long War broadens the amount of weapons available, both by increasing the number of weapon tiers, and increasing the number of weapons that are available in each tier. While there are weapons that are only available to one or a few classes, each class has several weapons to choose from.

Assault Rifles

Assault Rifles are the baseline rifle, providing a decent balance of mobility, accuracy and firepower. Their base ammo is 3 (increased by Ammo Conservation), and their base damage is 100%. Assault Rifles gain aim for being in close proximity (+5 aim per tile closer than 10).

Battle Rifles

Battle Rifles are heavier versions of Assault Rifles. They trade mobility and ammo capacity for increased damage output. Their base ammo is 2 (increased by Ammo Conservation), and their base damage is 125%. Battle Rifles gain aim for being in close proximity (+5 aim per tile closer than 10).

Carbines

Carbines are lighter versions of Assault Rifles focusing more on defense and consistency. They grant +0.6 mobility and a variable amount of Defense and Aim depending on tier, but have poor base crit chances and reduced damage. Their base ammo is 2 (increased by Ammo Conservation), and their base damage is 75%. Carbines gain aim for being in close proximity (+5 aim per tile closer than 10).

Shotguns

Shotguns have limited range but high damage. Their low base crit chances are offset by proximity/flanking bonuses. Their base ammo is 3, and their base damage is 150%. Shotguns gain extra aim for being in close proximity to a target (+8 aim per tile closer than 10) and lose aim for being in far proximity (-8 aim per tile further than 10).

SAWs

SAWs (Squad Automatic Weapons) are exclusive to Gunners. They deal more damage and carry more ammunition than Assault Rifles, but incur a penalty to mobility, cannot be steadied, and have low base crit chance. SAWs grant the Flush ability. Their base ammo is 4 and their base damage is 150%. SAWs gain aim for being in close proximity (+5 aim per tile closer than 10).

Sniper Rifles

Sniper Rifles are similar to the vanilla Sniper Rifles, and are only available to Snipers. Regular and overwatch shots operate at Squadsight ranges, and have lower Squadsight penalties (1 aim per tile instead of 2). Sniper Rifles require 2AP to fire, and cannot be used after moving or performing any other costly action. Sniper Rifles have variable penetration based on tier. Their base ammo is 3, and their base damage is 150%. Sniper rifles lose aim for being in close proximity (-16 aim per tile closer than 10).

MEC Weapons

MEC primary weapons, unsurprisingly, are only available to MECs. They don't have much crit chance, but deal maximum damage tied with SHIV weapons. They can target beyond visual range if the MEC Trooper has Squadsight. Their base ammo is 3, and their base damage is 200%. MEC weapons gain aim for being in close proximity (+5 aim per tile closer than 10).

SHIV Weapons

SHIV weapons, obviously, are only available to SHIVs. They deal maximum damage tied with MEC weapons, but suffer from low ammo capacity. They can be quite heavily customised by adding different modules to the SHIV loadout. Their base ammo capacity is 2, and their base damage is 200%. SHIV weapons gain aim for being in close proximity (+5 aim per tile closer than 10).

Arc and Stun Rifles

The Arc Rifle is a powerful anti-mechanical weapon, which gives bonus damage and penetration against mechanical units. The Stun Rifle replaces the Arc Thrower from Long War and is a primary weapon used to make alien captures. Stun chances have been increased significantly from base Long War; an alien with 1/2/3 health has 90/80/70% chances respectively, as in vanilla. The Improved Arc Thrower foundry project improves this further. In addition, failed stuns on aliens below 50% of their max HP will Maim. The Elerium Batteries foundry project grants an extra charge/ammo to both weapons and the Supercapacitor foundry project increases the Arc Rifle's damage against mechanical units by 2. Arc Rifles lose aim for being in close proximity (-16 aim per tile closer than 10).

Secondary Weapons

LWR contains a normal pistol for each weapon tier except Gauss, and a machine pistol for each except Laser and Pulse.

Units that cannot use secondary weapons: privates, gunners, and SHIVs

Units that cannot use sidearms and have unique secondary weapons: Rocketeers and MECs

All sidearms grant the Maim ability.

Pistols

Pistols are the default sidearm and cost no weight/mobility. They incur large aim penalties when fired at longer range, though the Ranger perk negates this entirely. Their base ammo is 2 (increased by High Capacity Pistols) and their base damage is 75%. Pistols gain aim for being in close proximity (+5 aim per tile closer than 10) and lose aim for being in far proximity (-5 aim per tile further than 10).

Autopistols

Autopistols grant increased crit damage and chance for a mobility penalty. Like regular Pistols, they incur large aim penalties when firing at longer range, though the Ranger perk negates this entirely. Their base ammo is 2 (increased by High Capacity Pistols) and their base damage is 75%. Machine Pistols gain aim for being in close proximity (+5 aim per tile closer than 10) and lose aim for being in far proximity (-5 aim per tile further than 10).

There are no Machine Pistol equivalents for either Laser tier.

Sawed-off Shotgun

The Sawed-off Shotgun is unique to the Ballistic tier, and provides a short-range, high-damage secondary weapon; it is useful for soldiers wielding a primary weapon that gets aim penalties at close range. It receives a +3 damage upgrade with the Foundry project Quenchguns. Sawed-off Shotguns gain aim for being in close proximity (+8 aim per tile closer than 10) and lose aim for being in far proximity (-13 aim per tile further than 10).

Rocket Launchers

Each rocket launcher is fitted with 1 rocket. The Rocketeer can equip a 2nd spare rocket. Rockets will scatter randomly around the aiming point according to a normal distribution. The tile value shown means there is a 68% chance that the rocket will land within that many tiles of the aiming point. Soldier aim does *not* affect rocket scatter but base HP can lower scatter (see: Effects of Attributes).

MEC Secondary Weapons

MECs have a variety of options for their secondary weapons, which like in Long War 1.0 are built separately and equipped on the loadout screen, rather than being integrated into a MEC suit.
