They are good at inflicting critical hits, and can augment the chances further with their special '''Headshot''' ability. Special training can allow the sniper to provide long range cover fire, disarm enemies or reconnaissance. The drawback being a sniper can't move and shoot except with the '''Snap Shot''' talent.

* The Sniper's primary weapon is the [[Sniper Rifle (EU2012)|Sniper Rifle]].

The Sniper relies heavily on positioning, favourable terrain and the cooperation of squad mates to locate their marks. The Sniper is otherwise a poor close range combatant. Rank promotions will give Snipers the biggest increase in Aim when compared to the other classes (+40 points total). Their drawback is that upon reaching Colonel rank a Sniper will also receive less 1 Health Point than any of the other classes (+3 total) but the same Will (+14 total)
* Each upgrade adds 2 points to Headshot's starting damage, so the Laser and Plasma versions will deal +4 and +6 damage to any hits.

* Sniper Rifles are also the only starting weapon that can fire at hostiles outside the units' view, using the '''Squad Sight''' Sniper ability. Pistols can shoot at Squad Sight range during Overwatch but this may be a bug.

==== Abilities ====
* Snipers Rifles can only be fired or used for Overwatch (except for a bug, see below) with a full 2 actions or not at all. The '''Snap Shot''' ability eliminates this requirement and allows the Sniper to Move and Fire. However, this ability inflicts an accuracy penalty on all Sniper Rifle attacks.

* Sniper Rifles suffer an aim penalty when targeting enemies in close quarters, requiring a switch to the pistol. Of all the classes, the Sniper relies on the Pistol the most.
 
* Support abilities upgrades are centered on four aspects: Actions, Aim, Defense and Damage Given.
 
:*Actions - '''Snap Shot''', '''In The Zone''' and '''Double Tap'''.
 
:*Aim - '''Headshot''', '''Squad Sight''', '''Damn Good Ground''', '''Battle Scanner''' and '''Executioner'''.
 
:*Defense - '''Damn Good Ground''' and '''Low Profile'''.
 
:*Damage Given - '''Headshot''' and '''Gunslinger'''.
 
:*Unique - '''Opportunist'''.
 
* Rank promotions will give Snipers the biggest increase in Aim when compared to the other classes (+40 points total). Their drawback is that upon reaching Colonel rank a Sniper will also receive less 1 Health Point than any of the other classes (+3 total) but the same Will (+14 total).

Sniper Squad
Sniper

A class able to inflict massive long range damage on enemy targets from a position of safety. They are good at inflicting critical hits, and can augment the chances further with their special Headshot ability. Special training can allow the sniper to provide long range cover fire, disarm enemies or reconnaissance. The drawback being a sniper can't move and shoot except with the Snap Shot talent.

Primary Weapon: Sniper Rifle, Laser Sniper Rifle or Plasma Sniper Rifle.
Secondary Weapon: Pistol, Laser Pistol or Plasma Pistol.

The Sniper relies heavily on positioning, favourable terrain and the cooperation of squad mates to locate their marks. The Sniper is otherwise a poor close range combatant. Rank promotions will give Snipers the biggest increase in Aim when compared to the other classes (+40 points total). Their drawback is that upon reaching Colonel rank a Sniper will also receive less 1 Health Point than any of the other classes (+3 total) but the same Will (+14 total)

Tips & Trix

  • Sniper Rifles suffer an aim penalty when targeting enemies in close quarters, making the pistol more useful than on other classes.
  • Snap Shot or Squad Sight, makes for two completely different play styles of snipers. Plan your build ahead.
  • A Snap Shot sniper is more mobile, while a Squad Sight sniper will stay back and deliver long-range fire.
  • Snap Shot snipers equipped with Battle Scanner can be great scouts and/or deliver devastating medium range. The Snap Shot's -20 Aim penalty can be overcome through Executioner and use of S.C.O.P.E.s but it will always take time to develop
  • Squad Sight is both a killer and a saver. It is one of the most essential skills to have in the early game.
  • But Squad Sight only works if the Snipers have a clear line of sight. This can limit their effectiveness in more built up maps like the larger UFOs.}}

Additional Notes

  • The sniper has the choice of taking Gunslinger or Damn Good Ground to either combat their weakness in close combat or capitalize on their strength. Mind that Gunslinger can be redundant if a Sniper possesses Snap Shot already.
  • The Battle Scanner can reveal groups of enemies without activating them, and can also be thrown through UFO doors. If equipped with the Battle Scanner Snipers may also scout for hostiles without the need to send (and risk) a squad member.
  • Snipers can also train on their unique Disabling Shot perk, allowing them to temporarily disable an alien's weapon. This is useful for captures, or to shut down Cyberdiscs or Sectopods that you won't be able to kill this turn. Disabling Shot is also very useful to prevent mind controlled squad members from firing at your soldiers.
  • Equipping the Sniper with armor that has a grappling hook is particularly helpful to establish a safe shooting position with wide field coverage and to use the Squad Sight and Damn Good Ground perks.
    • Archangel armor will also allow this. The sniper will benefit from Damn Good Ground while hovering.
  • Snipers may be trained to use their Pistols for greater damage (+2 points) with the Gunslinger ability, and can augment it further with higher tech pistols and the relevant Foundry upgrades.
  • On the PC: Snipers can overwatch with their sniper rifle after moving by reselecting the sniper and switching weapons. This can be a bit tricky on a Sniper who is flying with Archangel Armor, so another technique is to set a hotkey for Overwatch (through the pause menu or the main menu), and after moving your Sniper, have him/her wield their pistol, press the hotbutton for Overwatch, and click on the rifle icon on the lower right before the camera moves to the next trooper/Alien Activity. This is almost certainly a bug and cannot be done on the console releases.|}


Tactical Advice

The Sniper works exactly as you would expect: long range, high damage, low mobility engagement. Depending on the level and your position, a Sniper will either be an unstoppable murder engine snuffing out at least one enemy every round, or he'll spend most of the time running around useless trying to get a line of sight. Building a sniper revolves around managing their killing power while stationary versus their complete lack of it while on the move. Despite this, there are a number of no-brainer choices in their ability tree, greatly limiting the viable customization.

Abilities

RANK CORPORAL.png Corporal Snap Shot vs. Squadsight

Squadsight is the ability that allows your Sniper to actually snipe like the original game. In short, a soldier's ability to target enemies relies on the range of his weapon (100, or 66 game tiles for sniper rifles), having line of sight to the target, and being within vision range of the target (27, or 18 game tiles). Squadsight removes the last requirement, allowing the rest of your squad to spot for your sniper as he relaxes three-quarters of the level away. Squadsight allows you to make use of high ground more effectively (further amplifying your killing power), cover your squad as they advance, and actually hit anything, ever. Snipers that are not in vision range can not be attacked, making this ability an amazing boost to both offense and defense.

Snap Shot is a future investment. It is designed to help the Sniper contribute on maps in which obtaining line of sight is difficult. However, the accuracy penalty drops the Sniper's Aim from the best in the game to noticeably worse than both Assaults and Supports and sniper rifles suffer from an additional Aim penalty in close quarters. However this can be compensated later by other Sniper abilities (Damn Good Ground, Executioner) and equipment (Archangel/Ghost armor) to turn the Snap Shot Sniper into a mobile flying/stealth Marksman that will be very effective at midrange fights (around 10 game tiles). In The Zone will further turn it into a killing machine, by allowing it to move and kill outflanked targets without using any action.

RANK SERGEANT.png Sergeant Gunslinger vs. Damn Good Ground

Damn Good Ground rewards you for parking on high ground and blasting away, which is what you want to be doing anyway. This helps the Sniper as your go-to for getting rid of a high priority target, and partially makes up for the fact that you are generally shooting into cover. You should be shooting from high ground more often than you shoot your pistol, and Damn Good Ground accentuates that. Both Snipers will get a ton of mileage out of Damn Good Ground.

Gunslinger is the ability you want if you need a Sniper that can scoot and shoot. The boost to pistols is mostly effective to help snipers survive Floater and Thin Men ambushes. You won't be a force to be reckoned with in close range, but you'll contribute. Gunslinger is a little redundant for Snapshot Snipers, and becomes more so as abilities and promotions make up for the aim penalty. For Squadsight Snipers, Gunslinger will make the sniper more useful in situations demanding lots of movement, or where drawing line of sight is far more difficult, like larger UFOs.

RANK LIEUTENANT.png Lieutenant Disabling Shot vs. Battle Scanner

Disabling Shot is a nice option for when blowing a hole out the back of a target's head isn't an option. This ability is useful if you have a dangerous target you're not confident you can kill this turn (Cyberdiscs and Sectopods), if you're going for a capture, or to neutralise a mind controlled friendly. There is a small Aim penalty (-10) attached to this shot, and the attack does reduced damage; if going for a capture, make sure you don't accidentally kill the target.
Note: Disabling shot is the only thing you have that can prevent your mind controlled troops from flattening your non-mind controlled ones, short of killing them first; if killing the mind controller is not an option.

Battle Scanner is the best scouting tool in the game this side of Ghost Armor. Giving it to a Snap Shot sniper turns it into a scout/sniper unit. Scanning does not trigger enemies to take cover, so you can use this to get the jump on a pack of aliens, either landing a rocket in them while they're bunched up, or getting a free sniper shot on one out of cover. Its limited range means that the Sniper will not be in range to use it on open maps where he's miles away from his team, but a Sniper with Squad Sight can use it and it can be very useful in close quarters, especially with melee enemies afoot. Battle Scanners can be thrown through alien doors, making them handy in UFOs.

RANK CAPTAIN.png Captain Executioner vs. Opportunist

Executioner is nice when a wounded enemy absolutely needs to die, but there are two things to consider. First, the bonus itself is fairly minor on a class that already has great Aim but it can very useful for a Snap Shot sniper to deliver the killing blow. Second, snipers are generally able to kill most ordinary targets in one shot, which will keep the trigger condition from being relevant much of the time. When fighting very high hit-point enemies such as Sectopods, 50% of such an enemy's health amounts to quite a significant chunk of health. As the random number generator can be fickle at times, pushing your to-hit rate up to 100% against a major enemy is never a bad thing.

Opportunist improves your ability to cover the rest of the squad during Overwatch, helping mostly when aliens decide to patrol into your team blindly. With the range on Sniper Rifles, this ends up being a nice bit of coverage. Enemies triggering Overwatch are frequently in the open, partially reducing the need for this, but it's still an improved chance to save you time during your actual turn. The biggest sell for Oppertunist is that your Sniper's Overwatch shots can now score critical hits: with a Plasma Sniper Rifle on hand, pretty much any aliens, even Elite Mutons, that wander into view during Alien Activity are often dead on arrival, or at least severely wounded. If you go for two Snipers with Oppertunist, try to place them with different lines of sight, so that they're less likeley to waste a shot shooting at the same alien.

RANK COLONEL.png Colonel In the Zone vs. Double Tap

In The Zone offers unmatched offensive potential in the right conditions. Snapshot snipers, if armed with Ghost Armor, can sneak behind a squad of entrenched enemies and picked them off on the next turn. Squad Sight snipers will rarely flank an enemy, so will need to focus on exposed targets. Aliens that can't take cover - Chryssalids, Zombies, Drones, Cyberdisks, Muton Berserkers, Sectopods, and Ethereals -- and flying units (treated as exposed for the purposes of In The Zone) will be your primary targets. In the event that you kill an exposed alien with an overwatch shot, you'll get another non-move action next turn. Finally, squad mates can assist the sniper by blowing away cover with rockets or grenades. Note: In The Zone can be triggered with a pistol, but only once per turn.

Double Tap is both powerful and broadly applicable. For comparison, this is Rapid Fire (Assault) without an aim penalty, and the ability to re-target. You will never ever regret having it. If you took Snap Shot, keep in mind that second shot suffers -20 aim penalty (due to a bug) and you can't Double Tap after moving.

Equipment

Weapon: You can technically get by for a little while without upgrading your sniper rifles thanks to their good damage, high critical rate, and Headshot. However, a Sniper that can't kill targets in a single shot is not a very good asset to the squad, so you will want to keep up with tech here. Snipers also benefit from pistols much more than other classes, give them your best for those turns that they can't sit still or cannot fire their main weapon.

Armor: The best defense is a good offense. The second best defense is being too damn far away. Snipers have both of these, so you generally don't need to prioritize armor. Skeleton armor will help get you to a good position, and the defense bonus stacks nicely with Low Profile. Archangel is your go-to for the end game. A case for Ghost Armor can be made for Snap-Shot Snipers with In The Zone, as it will allow your Sniper to get into position with far less hassle. However, Ghost Armor can be expensive, and there are a couple other classes which should get the Ghost Armor first, so plan accordingly.

Item: Snipers generally get the most benefit from equipping a S.C.O.P.E. as it augments their already high accuracy and critical rate. If you're finding their normal aim progression to be sufficient, you may want to arm items that mitigate the snipers' close combat weakness such as a Nano-Fiber vest or Chitin plating. Alternately, arm equipment to provide additional functionality such as an Arc Thrower for capture, grenade for anti-cover, or another medikit.

Summary

All-around designed for long-range combat, one of the "Making the Gamer Harder" suggestions is simply "Never choose Squadsight." A Sniper with Squadsight and Damn Good Ground, flying high with Archangel Armor (an additional Defense bonus on top of DGG, for the rare time an enemy does get in range) and equipped with an upgraded Scope can pretty much ignore whatever cover aliens may have, and with Double Tap, one sniper fights like two soldiers, and two full snipers may seem like overkill. With Disabling Shot, the second shot can be used to simultaneously soften and disarm aliens for other solders to kill and level up with. With Opportunist, any alien that moves out of cover is almost a guaranteed kill. Watch your ammo levels, though.

With a six-member squad, and the UFOs and many levels having a degree of symmetry, a regular tactic is to send two 3-member squads on each path (a sniper with each, taking back positions), which keeps any aliens on the other path from flanking around: a well-positioned sniper will reach out and help with front-line combat, and should shoot first for any frisky aliens who try to rush through, like Chryssalids (who fall easily to a headshot even from the basic Sniper Rifle), rather than leaving the front-line troops move-less in attacking, or having them fall back to defend, leaving a gap for any more aliens to rush through. With that in mind, both Floater species are perhaps the biggest threat to snipers: their frequently-used Launch ability is utilized to flank your rearmost soldier, which will often be your sniper. Your mid-range fighters being close enough to provide backup, or another Squadsight sniper, and having them cover one another, is the best defense against this.

An excellent lategame tactic involves two Squadsight Snipers (and at least one with Opportunist), and a forward soldier with Ghost Armor: the Ghosting soldier "recons" for the Snipers, and finds a 3-member squad of aliens, unactive and out of cover. The Sniper with Opportunist goes into Overwatch. Then the other sniper fires, killing the first alien. Activating the squad makes the aliens go into cover, triggering the Overwatching sniper, which will have equal aim, problably also killing another alien. Lastly, the cloaked soldier takes their shot, at 100% critical chance, possibly finishing off the squad.

A Psionic Sniper is generally hard to train in open terrain situations, as you will not have the tendency to have them up front to attack with Mind Fray, though it is a valuable alternative to the pistol in the event of a Floater jump. "Psi Panic" has similar limitations when outdoors, and TK Field probably won't have the range to cover your front-line soldiers, who would benefit the most from it. Psi Inspiration can be used as a kind of support, boosting other psi soldiers before sending them forward to Fray/Panic/MC. Lastly, Mind Control is an excellent auxiliary move for any aliens that happen to flank the sniper.

For your early snipers, who will not benefit from Psi abilities like Mind Fray (and will have comparatively low will, even if they do test positive when you finally get to test them), Gunslinger may actually be the better option over DGG, if you find yourself often flanked or in situations where their starting position does not provide a clear shot (and you did not take Snapshot). With all the foundry upgrades for pistols, and Plasma Pistols, that's a base damage of 6: while not impressive, it's a decent holdout weapon for late-game.
