Plovdiv, the year 2XXX. Men have ceased to exist. Society is wholly under the control of mysterious shapeshifters who take the form of humans and monsters. Few believe the reports of their existence, and those who discover their existence don't often live long enough to tell the tale.
Aerannis is a game in which an assassin, Ceyda Farhi, uncovers the truth. Her missions involve sneaking around, taking hostages, using human shields, laying down traps, and assassinating those who are a part of the conspiracy. Countless massive, intense boss battles are seamlessly blended in with the stealth action.
