We thought we were winning the war until the enemy made first contact.

During a counterinsurgency operation against the Martian Royal Militia, Staff Sergeant Trenton Carver and his team of elite Marine Raiders make a startling discovery. Hard evidence suggests the enemy is allied with an extraterrestrial force that is in possession of game-changing technology… and they intend to take the fight to Earth.

The only way to secure Earth requires breaking this alliance with a daring first strike.

Lieutenant Colonel James Dunkirk is faced with tough choices. A split-second decision comes with career-altering consequences… but not in the way he expects. While his Marines navigate uncharted territory and fight like hell to survive, the Colonel must decide if he is ready to tear down the curtain and embrace an uncomfortable truth.

The real war is not just on Mars, and there are greater threats than the Martians.

When Special Agent Angelica Lofaro is called in from the Agency to investigate this new threat, she uncovers a conspiracy that threatens to end more than her career. Danger lurks around every corner—and it might just be wearing the face of an ally. As the power dynamic shifts in favor of the enemy, a new type of unit may be the only answer to a secret war that threatens to stamp out the light of civilization for all of humanity.

This is the origin story of the galaxy's most elite expeditionary combat unit: The Portal Raiders.
