Heroes aren't born but crafted and shaped by the US Army. Major Hammer is the ultimate proof of this statement. He is the fiercest warrior the modern world has ever seen and will face any mission with his 'do or die' attitude. Quitting is not a word allowed in his vocabulary, which is the testimony of his entire military career.

 

Major Hammer was abruptly selected as a highly decorated war hero for the ultimate mission: to seek and destroy all Cursed Immortals. Shortly, a virus and its vaccine ravage the world's population, turning many of them into bloodthirsty and nearly superhuman creatures. An all-out war for the survival of the human race breaks out and spills over into the coming decades.

 

The pivotal point of the war eventually comes when a young scientist invents a time disruption device, and both sides immediately race to possess it, believing time travel will end the Immortal Wars. The humans will use time travel to hunt and destroy their blood-letting enemies, while the Cursed Immortals will travel back in time to consume uncontaminated blood.
