If you ever thought "how they could make a good anime adaptation out of megaman x story?", this answers your question. It's short, only one episode, but if you like the megaman x franchise, this has some information before the start of the games.
The animation is ok, the style is similar to Megaman X4 cutscenes. The sound does not impress, same with the story. But its good to see the characters (X and Zero) in action. My only complain is that I was waiting for more fights.
