Bile Spewer

Bile Spewers appeared following unavoidable spills of toxic chemicals on Terminid E-710 farms. The Bile Spewer's thorax is bloated with several metric tons of corrosive acids, which it vomits in revulsion upon encountering Democracy.

Tactics

 * Appear on planets with bug missions from Medium level onwards. They are sometimes assigned their own special quest. They'll constantly spit bile at any Helldivers they target and it can hit from long range.
 * Armor wise, the front legs, spine and head of the Bile Spewer is protected via medium armor, while the side of its torso is completely unarmored, and its hind legs are only protected with light armor. This makes light armor penetrating weapons rather ineffective against Bile Spewers unless shot in their mouth as they are about to launch their bile attack.
 * Shooting at the Spewer’s torso with conventional ballistics is ill advised as it can slack up an impressive amount of bullets. Using explosive weaponry is preferable for body shots, while conventional ballistics should be used to target their heads.
 * A rather effective primary weapon against the Bile Spewer is the Slugger, as not only does it penetrates the bug’s armor, but it can also stagger the bug to disrupt its deadly bile spew.
 * A single well place grenade near or under the Spewer will often one shot or nearly kill them. The rail gun will instant kill with one headshot or two fully charged body shots. The grenade launcher and Autocannon will kill in two to three rounds and any other Spewer near the AOE.

Nursing Spewer

 * A sub-adult of the Bile Spewer, easily identified via its yellow coloring. It has the same stats as the adult but has slightly less tracking/damage on its main attack as well as less armor (only light armor on the top of its torso, head and limbs). In addition, it does not have the bile mortar mode as the full adult in harder difficulties (Suicide Mission and up).
 * Durability wise, the Nursing Spewer takes about as much damage to the head as a Brood Commander to eliminate, around 16 shots from a standard Liberator or 8 shots from a Liberator Penetrator.
 * A Nursing Spewer constantly emits a low-lying yellow fog that makes it easy to detect from a distance, but dangerous to leave alive in close-quarters. Killing the Spewer will quickly dissipate the fog.

White Spewers

 * A rare white variation of the Bile Spewer, the stats are currently unknown.
