The Hamidon War arc focuses on the monstrous, sentient amoeba known as Hamidon and its mutated creations. This arc often involves dealing with biological threats, environmental hazards, and the ethical dilemmas surrounding Hamidon's existence. You'll be working with scientists and specialized task forces to contain the spread of Hamidon's influence and prevent a global catastrophe.

This arc primarily takes place in zones like Eden and the Rikti War Zone, where Hamidon's influence is most prevalent. Expect to fight mutated creatures, Hamidon's 'children,' and potentially corrupted humans. The missions often involve collecting biological samples, destroying Hamidon's tendrils, or protecting research facilities.
