- "Back in your nest!"
- —JD Fenix
The "hatching process" of the Swarm's nests is relatively simple: first they sink into the ground and begin smoking whilst illuminated; afterwards, they burst open and the Imagos and/or Drones emerge.
Nests can be obliterated by using any explosive weapon, although throwing Bolo Grenades in them are the most effective method. Once destroyed, they create a sizable depression in the ground, allowing for anyone to take cover in it. A weapon or pair of grenades can often be found inside a destroyed nest.
