About the game

Crassus’ army box leads the player to take up the banners of the legions that the “richest man in Rome” formed to fulfill his dream of conquering the opulent Parthian Empire. He is accompanied by his son, Crassus Iunior, a skilled and courageous general, who had been trained in Caesar’s first campaigns in Gaul. His archenemy, Surena, responsible for his defeat and death at Carrhae, shares a box with both of them, ready to put his genius at the service of the Parthian armies. Crassus’ legions do not know what is coming, but with the help of the fearless vigiles and numerous eastern mercenaries, such as the Galatian legionaries and the Rhodian slingers, they may be able to defeat fate and change the history of the world. If not, the survivors of Carrhae can always make a name for themselves in the service of the armies of the distant Han Empire, beyond the other end of the Orb known to the Romans. —description from the publisher La caja de ejército de Craso lleva al jugador a tomar los estandartes de las legiones que el “hombre más rico de Roma” formó para cumplir su sueño de conquistar el opulento Imperio parto. Le acompaña su hijo, Craso el Joven, diestro y valeroso general, curtido en las primeras campañas de César en la Galia. Comparte caja con ambos su archienemigo, Surena, responsable de su derrota y muerte en Carrhae, listo para poner su genio al servicio de los ejércitos partos. Las legiones de Craso no saben lo que se les viene encima, pero con la ayuda de los arrojados vigiles y numerosos mercenarios orientales, como los legionarios gálatas y los honderos rodios, puede que sean capaces de vencer al destino y cambiar la historia del mundo. Si no, los supervivientes de Carrhae siempre podrán labrarse un nombre al servicio de los ejércitos del lejano Imperio Han, más allá del otro extremo del Orbe conocido por los romanos. —description from the publisher (Spanish)
