is it going to be co op

the game is really really good, origins was brilliant and i miss the warden hero, kinda wish he was the main guy but at the same time i like the direction the story is going in, hope the warden does return later in the series of games. ive only played a bit of 2 so i have no idea how the warden story will play in 2 but i would love to find out wat happened to the child and the warden
