Mia and David join the growing cast of characters that already has plenty of Ash as well as some great characters from Army of Darkness as well as the first Evil Dead. Just like in the film, Mia is temporarily able to ward off possession in the game. She is also able to turn the more fear she feels into more damage done to enemies. That is a nice combo for an Evil Dead character. David Allen is a beacon of hope who is able to turn fear into extra heath for himself and his team.
The new skins come as part of Season 1 or if you prefer you can purchase them as standalone content.
