(October 1, 3056)The winners of the Jade Falcon Clan - mercenaries of the Black Thorns squad - are looking for a lucrative contract. But commander Jeremy Rose and his fighters are interested not so much in money as in the opportunity to meet clan warriors in battle again. The border planet Walcott becomes the location of the new “spike” service. The clans' code of honor does not allow them to seize the planet by direct aggression, but, blocked from all sides, it resembles a besieged military camp. In addition, Walcott is an excellent springboard for unexpected raids into enemy territory. "Black Spikes" attack with lightning speed. A well-started operation threatens the mercenaries with complete extermination.
