I think it was two actual new levels, and then another two that were slight remixes of existing levels. Like, I want to say that they were about 3/4 the same as ones present in the main game, but they threw a new gauntlet for a stretch to liven it up. In any event, even the brand new levels weren't anything to write home about, and picking the two most obnoxious boss fights in the game to remix and also doing what I thought was impossible by making the submarine shark fight even longer than it already was by throwing in a new phase, isn't something that anyone should be rushing to use against the company. Splatoon is a much better example of that on the back of the sound test being locked to the Squid Amiibo that was only available in the US in the three-packs, even when they did the re-colors.
