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.
 * Can be killed by targeting their backs with explosives as any regular weapons will deal reduced damage. It is often better however to aim for the head as that is considered their "weak spot." Their heads can be targeted by anything and the damage will not be reduced, (take note that you may need some form of armour penetration to target the head.)
 * 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 body shoots. The grenade launcher will kill in two to three rounds and any other Spewer near the AOE.

Nursing Spewer

 * A sub-adult of the Bile Spewer. It has the same stats as the adult but has slightly less tracking/damage on its main attack as well as less armor. In addition, it does not have the bile mortar mode as the full adult in harder difficulties (Suicide Mission and up).
