From what I remember the 'tutorials' were hidden within the whole 'radio communication' thing which was totally MGS in style and there was absolutely no hand-holding. If you're like me and just totally skip all that kind of stuff, you'll miss the core gameplay mechanics being explained and be clueless about the parry system. I think this is why the game divided people and ended up being a love it/hate it affair
When you start a new file the first thing the game asks you is if you want to play the tutorial, it's very bluntly in your face. The tutorial covers (in order) Ninja run, attacking during ninja run, basic combat & parrying. None of this is hidden away in menus. The thing that it doesn't cover that it should is lock on. If you're talking about the move list then it's found under the help menu while paused.
The main thing that they could have explained better was how to execute the parry. I had no issues picking up on what they had to do but it was clear from the complaints that they didn't completely convey the information correctly.
