Do NOT play ZC2 without playing its Tutorial/Prologue first!
I'm adding this note prior to the game's launch, to make sure everyone experiences the game at its best.
The tutorial and prologue of this game are on a separate menu, right beneath play game button.
Do not go into the game without playing this first!!! The combat mechanics and explanations of past events are all there.
Don't miss it even if you played the first. The combat mechanics had several improvements and changes, and you will not be able to execute any of the advanced moves without learning them here. And if you didn't play the first game, the story will be much harder to understand.
The reason the tutorial is kept apart from the main story mode was because in ZC1 players would forget the advanced moves and play the rest of the game with no way to remember them. In ZC2 you can save your progress and try out the tutorial as many times as you want. The tutorial has some advanced techniques that will require practice and timing, and going through them to refresh combat skills can be a good way to make the game more enjoyable.
