The army box of Iulius Caesar allows, naturally, to put in command of your forces the well-known Roman proconsul and dictator, paradigm of all the later Roman generals and emperors. Alongside him also ride the resolute Titus Labienus -whose loyalty to the Republic will lead him to abandon Caesar and fight under the banners of Pompeius in 49 B.C.- and the energetic Marcus Antonius, right-hand man of the proconsul during the Civil War. The remaining 37 cards of this box of 40 offer the player emblematic units such as the legion X Equestris -true elite of the armies of the proconsul- the fierce XIII Gemina or the Gauls enlisted in the V Alaudae, as well as a good quantity of legionary infantry resulting from the reforms of Gaius Marius -known since then as the elite of the armies of the proconsul, as a result of the same, as “Mario’s mules” -, mercenaries like the skilled Cretan archers and allies of the Caesarian forces like the fearsome Germanic horsemen, a group of troops with which they aspire to bring Gaul, Rome itself… and the world to its knees! —description from the publisher La caja de ejército de Julio César permite, naturalmente, poner al mando de tus fuerzas al archiconocido procónsul y dictador romano, paradigma de todos los generales y emperadores romanos posteriores. Junto a él cabalgan también el resolutivo Tito Labieno –cuya lealtad a la República le llevará a abandonar a César y militar bajo los estandartes de Pompeyo en 49 a.C.– y el enérgico Marco Antonio, mano derecha del procónsul durante la Guerra Civil. Las 37 cartas restantes de esta cajita de 40 ofrecen al jugador unidades emblemáticas como la legión X Equestris –verdadera élite de los ejércitos del procónsul– la arrojada XIII Gemina o los galos alistados en la V Alaudae, así como una buena cantidad de infantería legionaria resultante de las reformas de Gayo Mario –conocida desde entonces, a consecuencia de las mismas, como “mulas de Mario”–, mercenarios como los diestros arqueros cretenses y aliados de las fuerzas cesarianas como los temibles jinetes germanos, conjunto de tropas con las que estas aspiran a poner de rodillas la Galia, la propia Roma… ¡y el mundo! —description from the publisher (Spanish)
