Humans have colonized the entire Solar system and prepared to make an interstellar jump. But war is always there - if humans are involved. Collision of interests along with a crisis of power between earth's colonies which were in good relations just yesterday leaded to a full scale space war. Key events take place on Mars.
- Our hero is a young and promising squad leader of a newly created Order of Crusaders - the new power, called in to stand as a reliable basis for current regime, to stand firmly in a global chaos - and give the System a chance to survive. He arrives on Mars by an order to join the Heavy Crusaders Battalion that is currently forming up - the 4th battalion.
- Our hero will take part in immense battles along with thousands of other participants, where he and his squad are just mere part of a huge battle. He will commit several dozens of diversions, when any excess noise triggers an alarm. He will have to use all his diplomatic skills to persuade neutral sides to support him, to trade with Corporations, to persuade war veterans to join his squad. Not an easy path to take for our hero but he must go through all that to become a Commander of the 4th battalion - the one and only Heavy Assault Crusaders battalion of the System!
