Having not yet finished Katana Zero, I cannot givve a fair rating, but from what I have experienced so far, it is an excellent game. You play as an assasin dubbed "The Dragon" by the media and your enemies, who wields a katana which can slice clean through enemies all with one satisfying button press. The eight-directional attack angles, combined with the ability to slow time and deflect bullets makes this game a joy to play. The combat feels so smooth and fluid, unlike any other game I have ever played. Also, the synthwave soundtrack is brilliant, with your character turning on his walkman before every level, playing a different track every time. Overall, this little gem of a game is LOADS of fun to play through.
