I haven't played the original Metroid, which this game is a remake of, but I can't imagine it holds a candle to Zero Mission. This game rules hard. The art is great, the music is great, it controls super well, there's plenty of challenge. I wish there was some way to track areas better so that I could remember where a specific area was that I couldn't access because I didn't have this one item then but I do now, but it's a game from 2004 so I don't care that much. Definitely recommend this one.
