I haven't played the Octo Expansion yet, but I heard some of the challenges can be brutal. If you're looking for more of a challenge, then try the Octo Expansion. Personally, the single player in Splatoon is pretty good. The first game had a more basic single player while the second game had a more varied, but not too challenging single player. However, the first game's final boss was pretty epic and, while not as good, the second game's single player's final boss wasn't too shabby either.
