I made an incredible discovery. After Cia’s story in Legend Mode (which was just the same as in the Wii U version), there’s an extension to the original main story! I suppose if I’d paid more attention to the game when it was announced I’d have realised this, but since I was going to buy it anyway I didn’t think to.
What is important about this new set of story levels, is not that there are new characters (Tetra and King Boaty McBoatface) as I knew about those, but that there are TWO new maps! Two! I didn’t even realise there was one! On top of that, they come with a new secondary weapon – the hammer – and several new enemies. And Phantom Ganon as the end boss, who you need to fight by batting back the energy balls he throws at you. It’s excellent.
So I finished all that off, and then did some more Adventure Mode.
