Ninja gaiden 2 es un Ninja Gaiden 4 ( Itagaky )

It's almost like the difference between the first Dead or Alive and Dead or Alive 4; the key gameplay remains the same, and you can really enjoy fighting and winning, but we're also throwing out a bunch of visual stimulation so that you can look cool and enjoy doing it while playing. So if I were to think about it that way, I would call this game "Ninja Gaiden 4," in terms of how far advanced it is over the first one.

I say that we now have four levels of difficulty. The lowest we have is the path of the acolyte, it's really something I have designed for people who have not played a lot of action games or aren't necessarily very good at action games; they would be able to get going and play well and get really far. In that sense, it's even easier, or more approachable than Ninja Dog difficulty in Ninja Gaiden Black; it's very important to give different difficulties for different skill levels.

Finally, while Ryu is fighting these ninjas, I notice the new health system, where part of Ryu's health bar actually regenerates when he's out of combat à la Halo (though like Halo, excessive damage will go past the "regenerative" portion and affect the more finite part of his health bar).

Basicamente dice, que en terminos de Avance con respecto al primero, son tales que el lo llamaria Ninja Gaiden 4..., que tiene cuatro niveles de dificultad, y que Ryu posee una nueva barra de salud, en la cual esta se regenera de forma muy parecida a los Halo...
