Tenchu (AKA: 天誅, てんちゅう) is a highly creative and classic game series that redefined the gaming experience of ninja themed games, which opened up a new world for ninja stealth action type of games. Its first work was born on SONY's PlayStation game console in 1998, and then launched on PS2, PSP, Xbox 360, NDS and so on game consoles, most of which were developed and published by Acquire from Japan. As a Japanese ninja action game that focuses on sneaking and assassinating themes, Tenchu's appearance made this type of game a hit for players around the world, and the subsequent Tenchu 3 became even more famous. So far, it has released eight works.

N is a classic and challenging 2D flash based game with simple graphics, very resistant to play. The action design of Ninja is pretty darned realistic and cool, which gives extremely high request to the player's reaction speed and balance ability.
