Survivors have reported that they have discovered a group of mutated and special infected zombies over the past few days. These infected are cunning by nature, highly agile, and very aggressive. Once they have their sight on you, escape isn't an option, just like hunters lurking in the dark, waiting for an opportunity to pounce.
Studies had pointed out that the common feature of this unique type of infected all shared a shared history of the medical condition "Goiter" before they turned.

Survivors, please work together to uncover the mystery that causes the infected zombies to change.
