Goliath (Long War)

   Goliath

MEC variant of the Gunner class. A Goliath is designed to be a human tank. They have the best HP progression of any class in the game and an unsurpassed selection of defensive perks. They have reasonable aim progression, but their selection of offensive perks is a bit lacking.

Tactical Advice

Intended Role: "Tank"

With the highest HP progession and plethora of defensive perks, the Goliath acts as the frontline bullet sponge for the rest of the team. It is the one unit that you would want to take fire from the heavy hitting alien units. With the Absorption Fields perk as the first perk to be available, The Goliath is able to heavily reduce any damage that it receives.

With perks like Automated Threat Assessment, Extra Conditioning, Shock- Absorbent Armor and Damage Control it becomes slightly more difficult for aliens to severely hurt the MEC and even if they manage to heavily damage it, the Repair Servos perk can give it even more survivability, by making it able to repair itself during longer missions.

The Goliath MEC is the only unit that XCOM has available that can reliably be called a tanking unit, as such it can act as a recon unit for the rest of the team, even though it is hampered by its less than stellar mobility. This is why it is good to use it in conjunction with Scouts and Assaults. Use the Scouts to do recon and the Goliath to have the enemies (hopefully) shoot at it, while the assault can go around for a flank.

Sadly the enemy isn't actually obliged to shoot at the Goliath, making its tanking role somewhat situational as enemy units can forego shooting at the MEC that is standing right in front of them, and instead shoot at a soldier in low cover behind the MEC. In this case, equipping short range, high damage weapons such as Kinetic Strike and/or Flamethrowers can make them regret letting your Goliath run free. You will probably want to strike a balance when building your Goliath between defense and offense/utility, since a purely defensively built Goliath will have little to contribute in the event that the aliens don't decide to attack it. Flush, HEAT Ammo, Collateral Damage and Packmaster are prominent offensive and utility perks. Advanced Fire Control, Close Combat Specialist and Covering Fire can let the Goliath lock down aliens with the threat of overwatch.

It should be noted that even with their high health, damage reducing and self repairing capabilities, a lone Goliath can still die quite easily during the later parts of the campaign. The most serious threats come from Sectoid swarms, which will deal many small hits that bypass absorption fields, and HEAT loaded bosses, which will hit WAY too hard to tank. It is never a good idea to place the Goliath under a full pod's worth of fire without any assistance.

MECs can be healed by Medikits, so in longer missions a Medic should top off the Goliath between enemy pods ¹. With some luck an upgraded Arc Thrower can be used to capture Drones, providing an unlimited source of +3 healing that is amazing for extended missions. The Repair utility of an arc thrower can also be used, but is generally not strong enough to use for primary healing. Another good idea is to equip it with HP-boosting items such as an Alloy Carbide Plating or Core Armoring, increasing the health it needs to tank. Skills that reduce enemy aim are never a bad idea, but be careful when boosting the Goliath's defense rating above that of the rest of your squad. Doing so will encourage the alien AI to change targets.

Shock-Absorbent Armor takes the Goliath's tanking potential to a whole new level, but must be used very carefully. If the Goliath flanks a unit on the approach, it will frequently run away from the flank and attack outside of range for full damage. Heavier units like Mechtoids and Cyberdiscs are not pressed to flee, but they are not obligated to stay in range of the damage reduction. Do not place the Goliath in a situation where it NEEDS Shock-Absorbent Armor to survive.

The biggest drawback of the Goliath is its rather narrow usability; it has one role which it does extremely well, but it is not as versatile as other MEC classes. Unless you are going to use it for its specific purpose, you might not want to get a Goliath.

¹ If time is willing, wait until AFTER repair servos finishes its effect before healing the Goliath. Healing before then will also consume repair servo charges.

Sample Builds

The Wall

Perk progression
-	Lance Corporal	Corporal	Sergeant	Tech Sergeant	Gunnery Sergeant	Master Sergeant
Perk by tier	Steadfast	Automated Threat Assessment	Repair Servos	Shock-Absorbent Armor	Damage Control	Extra Conditioning
Build Overview
Stat Boosts	+11 will, +4 aim, +1 mobility
Strengths	nearly invincible tank
Weaknesses	struggles to find use outside of absorbing fire
Preferred battle sites	All, especially heavy contact missions
Most common Loadout	Heavy Exo Suit, Core Armoring, Alloy Plating, Holo-Targeter
Power Ranks	all perks give tank
Description	This is it. The tankiest unit XCom can possibly field. When properly fitted it takes multiple turns of heavy, concentrated fire to bring this monster down. Use this to draw enemy fire and absorb damage while the rest of your squad deals with the enemy. Never equip any item that increases defense or enemies may ignore the MEC entirely. For more utility at the cost of some tank Steadfast can be dropped for Flush, though this makes an Alien Trophy a necessary item.
Strategic Analysis	Even though the Goliath's low aim make its primary weapon quite unreliable at mid to long ranges, you can give it a more supportive role by equipping a Holo-Targeter. For secondary weapons consider bringing a grenade launcher or two to destroy enemy cover while in One For All position for extra DR. Furthermore while this MEC is indeed an absolute behemoth it has the same Achilles’ Heel as any other mechanized unit, HEAT. HEAT warheads and even ammo is occasionally found on some Alien pod leaders (especially Heavy Floaters), and can deal a nasty chunk of damage if not dealt with decisively. Also be wary of Acid which will shred off most of your DR temporarily.

Anti-Melee Punisher

Perk progression
-	Lance Corporal	Corporal	Sergeant	Tech Sergeant	Gunnery Sergeant	Master Sergeant
Perk by tier	Reactive Targeting Sensors	Covering Fire	Repair Servos	Shock-Absorbent Armor	Damage Control	Close Combat Specialist
Build Overview
Stat Boosts	+11 will, +4 aim, +1 mobility
Strengths	strong tank, single-handedly nullifies and dispatches melee units
Weaknesses	struggles to find utility against non-melee enemies
Preferred battle sites	All, especially terror missions
Most common Loadout	Heavy Exo Suit, Core Armoring, Alien Trophy, Holo-Targeter
Power Ranks	TSG for tank, MSG for dmg
Description	This MEC is designed to fight Chryssalids and Berserkers who charge at it, or to get right next to enemies and then punish them if they take any actions. Unlike the Marauder, the Goliath has access to Covering Fire, allowing it to shoot an enemy that attempts to attack at melee range rather than only when the enemy moves within CCS range. Advanced Fire Control is not needed since your Goliath will be firing at close range and AFC won't make a difference against melee enemies with Lightning Reflexes, which you still need to be wary of. A Flamethrower and/or Kinetic Strike Module will be ideal for this build, depending on what you are facing.
Strategic Analysis	Melee enemies will always run toward and attack the closest enemy, so simply keep this MEC between them and the rest of your squad. While this soldier does generally dispatch of Chryssalids easily, if a Chryssalid’s attack does connect if can apply acid which will cut into your tank significantly. Consider softening them up with explosives even if you need the Goliath to solo the pod for a turn. Always bring this soldier on terror missions, as it absolutely blasts through terror missions with large numbers of Chryssalid/Zombie pods.
