Terminids

The ravenous are guided solely by an instinctive urge to reproduce, spread, and destroy democracy. They are a fast-evolving plague, a shape-shifting infestation that threatens to devour and disenfranchise every single child on every single planet. Coincidentally and ENTIRELY UNRELATED to the war effort against their reign of terror, the Terminids also happen to be natural producers of oil.

They are one of two factions Helldivers can currently fight against, with the other being the Automatons.

Trivia
The Terminids are often derogatorily referred to as Nids and Bug Brains
