While they don't have as many tactical assets as the other factions, such as MG Turrets and Cover Deploys, they make up for it with an extremely diverse roster of specialist soldiers. Their guns are accurate and very deadly, but have low ammo caps and fire rates. Their special guns consist of specialist gear. Their elite units also spawn more often than the other factions'. Soldier Types:
Muton: Refer to the standard soldiers of the other two factions.
Outsiders: These units are marksmen who use single-shot and burst-fire plasma weaponry.
Floaters: Fodder unit. Very common, wield the same weapons as Outsiders, but aren't as accurate.
Thin Men: Similar to XCOM and EXALT's covert units. However, Thin Men spawn far more often.
ADVENT Soldier: Human turncoats who act as shock troopers for the aliens. Their guns are full-auto, as opposed to traditional alien weaponry.
ADVENT Stun Lancer: Rusher unit with a full-auto rifle. Will disregard cover to move in close to their targets, and faster than normal units.
Muton Elite: Armored Mutons who use the Fusion Bomber (full auto grenade launcher) and the Suppression Rifle (high ammo cap LMG.)
Outsider Elite: Use the Plasma Sniper and the Stormgun, a deadly alien SMG with an extremely high rate of fire, but low ammo cap.
ADVENT Captain: They use modified MAG guns that fire two projectiles per shot, while retaining the same fire rate.
Muton Berzerker: Fast and Tanky melee-only unit that will charge its enemies and attempt to disrupt their ranks.
Ethereal: Psionic units that use their mind as a weapon. Extremely deadly, but a rare sight on the battlefield.
