Still fun in 2018!
Matrix is really a movie that hasn't aged and this is probably the best flash game dedicated to it.
The mechanics of this game are amazing and provide a lot of depth to fast paced fighting. The game requires both tactical thinking and fast reflexes. The enemy variety and how they use environment and respond to your attacks is excellent game mechanics and so is the destructible environment - something you won't find in most modern games even. I really like the interactive environment of this game.
The arcade mode is great especially the last boss, it was a challenge and a little Star Wars crossover was very cool to make an ultimate villain. I defeated him on my 20th attempt or so, he was really cool and I liked how part of the challenge was sometimes understanding who is you and who is the boss.
The FreeStyle mode where you can create your own levels with your own preferred environment and enemy variety and density is what makes this game simply perfect.
