Someone is still salt after the initial release of unity, honestly i only had one or 2 glitches during my playthrough and they weren't game breaking. This DLC was pretty fun, we get to see a depressed Arno near the end of the french revolution where he has basically become a sad fart, but meeting a little boy who still has hope for a better france despite his parents leaving him. It has sort of a "ahhh arno is reborn ending" because the little boy paved arno a happier future knowing he still can make a difference.
There is a bit of content thought with a couple hours of the main story, side missions, and collectibles. I thought raiders were fun to mess with, because all you gotta do is kill the leader then they poop themselves, and it would be funny using the cannon on a pack of 15 of them.
I really liked this DLC, and it was free so you can't complain.
(also cool outfits)
