Shrieker

The Shrieker is a further mutated C-Virus Zombie which has undergone rapid and uncontrolled growth of lung tissue, so much so that the lungs have now sprouted from the chest cavity and look more akin to a large tumour. This growth has expanded their lung capacity enormously which means they now have the ability to take a huge breath and, as the name of the creature suggests, shriek in an extremely loud, prolonged fashion. The noise is so loud that it can permanently damage hearing in other creatures and even kill some others.

To aid the growth of their new lung tissue, their necks have extended upward, but their lower jaw has remained close to the chest leaving them with a large gaping mouth.

As the mutation has largely concentrated on their lungs and their heads the rest of their bodies are relatively normal. Unlike most t-Virus and C-Virus mutations, their extremities appear quite normal which is unusual.

In terms of engaging with a Shrieker, the first thing to do would be to target the lungs and attempt to destroy them with gunfire. This only appears to stun the monster momentarily however as the lungs regenerate at an alarming rate. However, if persistently fired upon the lungs will ultimately fail which then causes a chain reaction inside their body ultimately killing them from the shock.

In their death throes they tend to let out one final ear-piercing scream which somehow only seems to affect C-Virus Zombies in the immediate area. Upon hearing this tone, they are instantly killed, most likely their death sound triggers something in their brains which shuts them down permanently. Living human beings, animals and stronger infected appear to be unaffected by this.
