Creole assassin Aveline of Assassin's Creed 3: Liberation can manipulate the perceptions of others through the Persona System, navigating the community of 18th century New Orleans through using different disguises, according to a post on the PlayStation Blog
Aveline can don three separate and very different guises: that of a lady, a slave, or an assassin. Aveline retains the higher-class privileges of her French father's status; this combined with traits inherited from her African mother allow her to fluidly slip between social strata.
As a slave dressed in peasant's clothing, Aveline can easily escape detection as most people will overlook her presence. She can also rile her fellow slaves to cause a public scene, although she cannot use her assassin weapons in this guise.
In the clothes of an aristocrat, Aveline can access places that allow only members of high New Orleans society. Aveline can charm, bribe, and easily orchestrate opportunities for an assassination. As with her slave garb, she cannot use many of her assassin's weapons when tied into a corset, but she does possess certain modified items such as a poison dart-shooting umbrella.
Aveline's assassin's costume is tailored for combat, allowing her to carry more weapons. But at the same time her garb will call more attention to her presence: guards will be more alert of her while she's wearing this outfit.
Assassin's Creed 3: Liberation is coming to PlayStation Vita on October 30th.
