For the colony to survive, the Commandos must go on the offensive!

Lieutenant Warden's Marines have driven the enemy from New Bristol and saved the colony but they're not yet in the clear. Now they face a new challenge; the imminent arrival of an enemy fleet.

Together with the colonists, Warden and Atticus mount a guerrilla war against the invaders, driving them back in an attempt to save the city and secure the colony. But the invaders have their own plans and resources.

Huge walking tanks, massive production facilities and advanced technology are all deployed as they try to break the Royal Marines and take the planet from the colonists.

Can Warden and his Commandos hold out until the Royal Navy arrives?
