The USMC will never die.
On their way to a science station on Europa, their ship is destroyed and a small group of Marine Raiders in stasis are hurled into deep space.
Hundreds of years later they are discovered by a secret research station of the Socialist Organizational Governance which now dominates and oppresses the human race. The Marines, commanded by Gunnery Sergeant Wolf Mathison will be executed upon their return to Earth. Hated relics of a bygone era and a nation that was nuked into oblivion.
What their SOG captors don’t know is the Marines are equipped with outlawed implanted AI's that boost their reflexes and combat capabilities.
The Marines escape as the science base suffers a disaster and the Marines meet the Aesir, a group of near immortal warriors fighting SOG.
