Two of the images follow suit with the announced weapon type; one appears to be a harp-like instrument, and the other resembles a cannon-type gun. The third image looks to be more like a golem, which might be a mount or a wearable suit. All three images can be viewed after the break.
Are these really the first images of the mysterious new classes? We have contacted NCsoft for comment and will update the post when we hear back.
[Update: The images are official and the classes are tentatively known as Musician, Gunner, and Rider.]
