Techu Z, The "Gran Turismo" of ninja games
I never get bored of this game, always try to clear each stage differently (high replay value), for instance I may try clearing the stage by eliminating my primary target only and not killing anyone else while not being detected in the process, challenging but, rewarding much like the Demon/Dark Souls franchise, A "One more try" kind of game that keep you comming for more! If you like your ninja games slow paced with a bit of realism and strategy this one is for you, Its like "chess" with ninja's.
Co-op is amazing, I system linked this game with 2 friends thoroughly enjoyed the experience..
