The Mediterranean Defense was a collection of strategic contracts given to Assassin apprentices in Constantinople during the Renaissance. Coupled with the direction of Ezio Auditore da Firenze, the defense of the Mediterranean proved critical not only to the recruits' development but also to the expansion of the Assassins' knowledge and influence in the region.
During the early 16th century, the Assassin Brotherhood – under the direction of Ezio Auditore, the Mentor of the Italian Assassins who happened to be visiting Constantinople at the time – sought to expand its influence throughout the Mediterranean; considering this, they began to send apprentices and recruits to usurp cities controlled by the Templar Order. Their exploits ranged from simple acts, such as protecting merchants and officials who were loyal to the Brotherhood or against the Templars, to greater plots involving assassinations and freeing jailed allies. Some special requests, specifically the survey requests of Piri Reis, involved the Assassins traveling to certain cities and mapping the area.
Many of these cities were eventually freed from Templar rule and came under Assassins' control. However, a constant danger in the possibility of Templar reprisal remained at hand. As such, the contracts needed to be completed regularly to maintain the Assassins' control of the city, though should their grip on the locations fall too low, the Templars would attempt a reclamation of the city, forcing apprentices to rally a defense.
The Brotherhood took special care to improve the standard of living in these regions by improving daily income and providing many opportunities for their newly liberated citizens. The apprentices who were sent on these missions gained experience, and the Assassin Order gained funds to further their operations, as well as regular benefits and bomb ingredients. After a local guild was established, certain apprentices from Constantinople could also be assigned to become permanently based in one of the cities. There, they provided protection and solidified the Brotherhood's goals more directly.

- Rhodes was only unlocked in Mediterranean Defense after playing a multiplayer match on each map in the city, namely Knight's Hospital, Souk and Ippokratous.
- The achievement "Armchair General" could be earned by controlling all of the Mediterranean cities (except Rhodes) simultaneously.
- Some Mediterranean Defense missions had a reward of automatically recruiting one apprentice into the Order, though this was only valid if Ezio had vacancies in his roster.
- Managing Assassin Guilds increased the percentage-of-control capacity of the city. A city with no Assassins garrisoned had a percentage-of-control capacity of 50%. The maximum amount of Assassins garrisoned permitted was 5, where the percentage-of-control capacity was raised to 100% when a city's garrison was staffed by fully-trained Assassins. Placing 5 low-ranked Assassins in a city yielded a percentage-of-control capacity spanning from 50% to 100%.
- Every 20 minutes, at the same time as Ezio received a revenue deposit at the banks from city renovations, all of the cities lost a random percentage of Assassin control or gained the same in Templar control if relevant. If that percentage reduced Assassin control to 0%, the Templars would lay siege to the city.
- Some city missions required a specific fighting style from an Assassin recruit to be assigned as the first Assassin of the operation. There were four types, each signified by a symbol near their rank number: a marksman (crossbow), an enforcer (heavy weapon), a scout (short blade), or a soldier (Hidden Blade).
