Assassin's Creed 2 producer Vincent Pontbriand has said the city in the game, Rome, is the largest and most varied ever created for the franchise.
Speaking with UGDB, Pontbriand said when creating Rome, the development team tried to be as historically accurate as possible, while still making it a "unique and entertaining" experience.
"For the locations, we’ve decided to make the biggest city ever created in any Assassin’s Creed game so a lot of the action takes place directly in Rome (less loading required this time since Rome is one huge map)", said Pontbriand.
"Again, Rome is a huge playground and with the Rome Upgrade system, the secret locations, the side missions, brotherhood recruitment and management, collectibles, factions upgrades and so on, there is constantly a lot to do.
"Also, there are unique missions, which require Ezio to travel to other locations in Italy (Naples, Monte Circeo, etc.)! You’ll get to visit the interior of various landmarks or get to travel to a small countryside city to destroy a unique war machine designed by your friend Leonardo.
"Finally, Rome is also the most varied city we’ve created, in terms of architecture and number of landmarks. There are many different districts in the city, from Antique to Medieval and to the Renaissance district.
"With Assassins’s Creed, we always strive to be the historically accurate in the representation of the cities and the events that are in the game. Research is the foundation on which our work is based on, so long as it provides players a unique and entertaining experience".
Assassin's Creed: Brotherhood is out on November 16 in the US and November 19 in the UK for PS3 and Xbox 360. PC version is coming next year.
