When the Marines are separated nothing will stop them from coming to each others aid.
After the Republic turns on them, the Marines escape to investigate a missing Aesir Erikoisjoukot team that may have encountered the new enemy.
As the Vapaus Republic tears itself apart the Marines are separated. Their loyalty is tested as they seek to reunite and take the battle to the real enemy. Gunny Mathison and Private Stathis are trapped aboard an enemy ship while Warrant Officer Winters and Sergeant Levin must face an elite Republic Hyökkäys Kaapata Tiimi sent to capture them.
Skadi and her Erikoisjoukot are sent away to help support an attack on SOG, but little do they know that SOG is preparing an ambush for the largest fleet the Republic has ever assembled and there may be traitors in the Republic ranks.
They will meet at the Gates of Hell if that is what is needed but Marines never leave their own behind.
