At the dawn of the Dark Ages the Roman Empire descends into chaos due to volcanic changes rocking the empire as apocalyptic signs foretell of a great scourge to sweep across Europe. Upon the death of Emperor Theodosius I in 395 AD, the empire is divided between his sons who each rule a half: Honorius in the West, and Arcadius in the East. Since the days of Diocletian it has become a custom to divide Rome as the pressures to govern the empire have become too much for a single emperor to handle. With the split of the empire both sides face multiple threats on all sides, including internal instability undermining each of the young emperors' control as part of the long-term repercussions of the Third-Century Crisis. When the game begins, playing as the Western Roman Empire, players will face waves of hordes entering their borders as the arrival of the Huns in the east and the devastation they have caused have forced them to flee in search of new homes. Since the death of Emperor Valentinian I and the division of the empire, the weaknesses in the West have rapidly begun to show and edge the empire closer to ruin. With depleted funds from centuries of internal mismanagement and corruption, the West is unable to muster an effective army to combat the invaders. While players will start the campaign with vast territories under their command, it will quickly become a game of survival as Rome's legions are stretched to breaking point to protect a decaying empire. The Eastern Roman Empire, however, has profited from the division to take control of the civilized world as it begins its transformation into a new empire. With the new administrative capital in Constantinople serving as the gateway for trade between Europe and Asia, along with economic reforms, the eastern empire has become an economic powerhouse in the game. Yet, the Eastern Romans face an initial threat from the Visigoths led by Alaric I in Greece, who makes a direct assault on Constantinople itself, and remain wary of the Sassanid threat in the East. The Romans must find new ways and technologies to cope with this changing world if they are to survive as the old technologies and antiquity systems no longer apply, along with the increasingly growing power of the Church becoming ever more influential. If players choose to play either of the Roman empires, they will be tasked with saving and preserving the once-great empire, and if possible unite Rome under a single emperor.
Features
As Total War: Attila embraces an era of great change with the people of Europe migrating across the campaign map, Attila adds a new dimension in the form of a faction's religious conversion in the game that brings an array of unique benefits across the player's empire depending on the religion that they choose to favour. The presence of a faction's state religion offers bonuses, including provincial edicts assigned, temple buildings, churches, and even character traits. These factors all play an important role in how dominant the player's religion is over a province. If a province has a population with several religions, it can have a negative effect on public order and thus lead to revolts. Factions also suffer or gain religious penalties when engaging in diplomacy with each other depending on their chosen religious affinity. Should the player choose to convert to a new religion, their faction's overall population must have at least 35% of that religion to convert. To find which religion is dominant in a region, the campaign map may be searched using the religion filter provided. For players who choose Christianity as their state religion, the five cities of Rome, Constantinople, Aelia Capitolina, Antioch, and Alexandria that formed part of the Pentarchy have the exclusive option for their churches to be upgraded to "Holy See" status, which comes with major bonuses. The game includes a total of 13 religions available throughout the campaign map, although the effects of minor religions are not fully understood.
The game also introduces the ability for players to use their armies to raze settlements once they have been conquered. This new feature allows the player to enact a "Scorched Earth policy" which destroys the land around the nearby settlement, crippling the enemy's food and money supply. Attila also lets a faction who did not originally begin the campaign as a horde to abandon its settlements at the cost of burning those former settlements or simply abandon a chosen number of cities which before being destroyed, will provide a small amount of wealth to the treasury. However, it is advised to analyze which settlements players destroy; recolonizing it would cost a faction a hefty amount of gold, a separate cost from building expenses to reach its former state.
Based on historical accounts, a mini Ice Age in this period plays a part for the people of Northern Europe to move to the more fertile south as the winter cold moves further down and engulfs Europe in longer winters as the game progresses. As an added new feature included in Attila, the Fertility of a region plays a crucial part when settling in a region if playing as a migrating horde or creating important buildings that deliver food throughout your empire. The campaign map is divided on various fertility levels that are color-coded and labeled; from highest-lowest: Rich, Good, Average, Poor, Meagre, Infertile. The greater the fertility level, the greater the amount of food can be cultivated with the appropriate buildings. However, the amount of food harvested is affected by a number of various external and internal factors. These include: building consumption costs, razed areas within your controlled province, provincial edicts, character traits, foreign armies raiding within your borders.
