Elemental weapons are unique because they don't fire bullets, rockets, rays or grenades such as other weapon types. Instead they spray hazardous clouds which affect soldiers with status effect. There are 4 status effect: fire, ice, poison and electricity. Elementals are the only weapons in game that affect soldiers with status effects automatically, others only have chance for that or don't have that ability at all unless you equip them with elemental Rounds. Like shotguns, Elemental weapons have very short range of fire, but their great advantage is lot of ammo and no reloads. Custom versions of Elementals all have reduced ammo consumption.
Elementals can easily hurt you if you don't use them properly. Don't fire below yourself or while standing too close to the enemy you're aiming at, status effects can affect you and your teammates too and they are deadly. If you can't control Elementals, use Shotguns for Juggernaut and Experimental Weapons for Elite instead.
