Another new addition to Liberation is the concept of a persona system. Under this system, Aveline can be in one of three disguisesan assassin, a servant, and an aristocrat. Each one functions differently.
In her assassin guise, Aveline is adept at combat, jumping across roofs, and so on. The downside is that she sticks out like a sore thumb, causes fear wherever she goes, and soldiers attack her on sight. In contrast, the servant guise allows her to blend in with the masses of New Orleans underprivileged society. She can mingle with cleaners, dock workers and other low-class workers without anyone raising an eyebrow, but is lightly-armoured and cant take a beating.
Finally, the aristocrat guise is her public face, or her Bruce Wayne persona, if you want to look at it that way. She was raised by her fathers wealth, and this is how society at large sees and knows her. Shes charming, beautiful and influential, and can use these qualities to simply bypass a lot of the obstacles that would otherwise stand in her way. In this guise, she carries a parasol gun, which is a one-shot stealth weapon, but cant run or fight.
