Weapons (XCOM: Enemy Unknown)

Weapons, primarily firearms and explosives, are used in combat by XCOM soldiers and most aliens in XCOM: Enemy Unknown, as well as EXALT's paramilitary agents in XCOM: Enemy Within.

Soldiers equip weapons based on their class, which can be seen in the Barracks or while selecting a squad for a mission. Alien species always make use of the same weapon(s) with the exception of the Muton (see Alien Weaponry below). While weapons can be captured from aliens which have been stunned by the Arc Thrower or had the difficulty turned down to a point where their health value becomes 0, they cannot be used until the associated research project has been completed. Newly researched weapons become available for production in Engineering whereas conventional weapons (available by default) are already stocked in unlimited quantities.

Weapon TypesEdit

Soldiers carry a primary weapon, secondary weapon, and an item (two with Tactical Rigging in XCOM: Enemy Within). Primary weapons are a soldier's main source of firepower in combat; they include rifles, sniper rifles, shotguns, and LMGs. Secondary weapons vary; they include pistols, rocket launchers, and a wide range of tactical subsystems available to MEC Troopers that are installed directly to a MEC^EW. A soldier's item slot can hold a variety of grenades, a S.C.O.P.E. to improve equipped weapons, or an Arc Thrower to capture live aliens, among other useful equipment.

Technology LevelEdit

On occasion a class ability (such as the Sniper's Headshot or a Heavy's Mayhem) is related to the weapon's technology level. These are, in order:

• Level 1: Conventional weapons
• Level 2: Beam weapons and Railgun ^EW
• Level 3: Plasma weapons, Alloy Cannon, and Particle Cannon ^EW

Alien WeaponryEdit

PlasmaEdit

A number of alien species are equipped with plasma-based weaponry equivalent to XCOM's:

Plasma Pistol:	Sectoid, Sectoid Commander, Seeker EW
Light Plasma Rifle:	Floater, Outsider, Thin Man
Plasma Rifle:	Heavy Floater, Muton
Heavy Plasma:	Muton Elite
Alien Grenade:	Cyberdisc, Heavy Floater, Muton, Muton Elite, Sectoid Commander

Notes:

• Mutons use Light Plasma Rifles when first encountered (in May) before switching to Plasma Rifles for the remainder of the game. This change occurs in June on Classic/Impossible difficulty, or in July on Easy/Normal difficulty.
• Cyberdiscs, Heavy Floaters, and Muton Elites can throw grenades farther due to their Bombard ability.

In addition, many aliens employ specialized weapons or offensive capabilities that are unavailable to XCOM and unique to their species:

RangedEdit

Weapon	Species	Base Damage	Crit Damage	Crit Chance
Chest Cannon	Sectopod	9 - 11	15 - 17	10%
Cluster Bomb	Sectopod	6	N/A	N/A
Cyberdisc Cannon	Cyberdisc	7 - 9	12 - 14	25%
Drone Beam	Drone	1 - 3	3 - 5	10%
Plasma Mini-cannon	Mechtoid EW	6 - 8	10 - 12	0%

MeleeEdit

Weapon	Species	Base Damage	Crit Damage	Crit Chance
Chryssalid Claw	Chryssalid	6	11	20%
Muton Blade	Berserker	9	13	33%
Zombie Fist	Zombie	8	N/A	N/A

EXALT WeaponryEdit

EXALT initially uses conventional weapons before upgrading to beam weapons. Name and outward appearance aside, their weapons are identical in stats and function to XCOM's weapons.

Encountered EXALT armaments can be on par with up to XCOM's laser weaponry. As they don't possess Plasma-based gear, a sufficiently-upgraded team can easily outgun them in combat.

Weapon	Base Damage	Crit Damage	Crit Chance	Range
EXALT Assault Rifle	2 - 4	5 - 7	10%	Short
EXALT Laser Assault Rifle	4 - 6	8 - 10	10%	Medium
EXALT Sniper Rifle	3 - 5	6 - 8	25%	Long
EXALT Laser Sniper Rifle	5 - 7	9 - 11	30%	Long
EXALT LMG	3 - 5	6 - 8	0%	Medium
EXALT Heavy Laser	5 - 7	9 - 11	0%	Medium
EXALT Rocket Launcher	6	N/A	N/A	Long

Range Bonuses and PenaltiesEdit

Weapons are subject to Aim bonuses and/or penalties, based on the weapon type and distance from the target.

	Pistols	Rifles	Sniper Rifles	Shotguns	LMGs
Aim Bonus	✓	✓		✓	✓
Aim Penalty			✓	✓

Range Bonuses

Pistols, Rifles, LMGs
Distance	1	2	3	4	5	6	7	8	9	10
Aim	+37	+33	+28	+24	+19	+15	+10	+6	+1	0
Shotguns
Distance	1	2	3	4	5	6	7	8	9	10
Aim	+52	+48	+40	+36	+28	+24	+20	+12	+8	0

Range Penalties

Sniper Rifles
Distance	1	2	3	4	5	6	7	8	9	10
Aim	-24	-21	-19	-16	-13	-10	-7	-4	-2	0
Shotguns
Distance	10	11	12	13	14	15	16	17
Aim	0	-4	-8	-16	-20	-28	-32	-40 (Maximum) [1]

Weapons are zeroed (no Aim bonus or penalty) at a range of 10 tiles. The Aim bonuses and penalties above are based on straight-line distances and cardinal unit positioning. Angled positioning with a Shotgun or Sniper Rifle can result in an Aim bonus/penalty corresponding to values within ±1 tile of the straight-line distance (calculated using Pythagorean theorem).

BugsEdit

• Critical hit damage may vary from what is listed in a weapon's Tactical Info due to a calculation bug. They may inflict one point less than the indicated minimum, and/or be limited to one point less than the indicated maximum.

Trivia Edit

• EXALT does not utilize shotgun type weapons, nor do they use pistols. Their gear also caps at laser-based weaponry in terms of advancement, therefore no plasma-based EXALT armaments can be seen on the field.

• Aliens do not utilize neither shotgun type weapons, nor sniper rifle type weapons, although they have some more unique weaponry.
