Ultrahumans - War Against The Nemesis

The portals appeared without warning. What came through them was worse. They called the creatures Nemesis—unnatural beings of flesh and metal with glowing red eyes, serpentine bodies, and abilities that defied everything humanity understood. Cities became hunting grounds, entire districts were abandoned, and survival became a matter of firepower. Then humanity found a way to fight back. Through ACANI, volunteers undergo the Rebirth protocol, awakening abilities far beyond ordinary human limits. Lightning. Frost. Darkness. Blood. Ten different paths to power, each capable of turning an ordinary person into something capable of hunting the monsters. They are called Ultrahumans. But the portals are growing. And whatever is sending the Nemesis through them has only just begun.
