I'm gonna be honest, it's not worth playing. It's probably the worst aged game on the entire Metroid franchise. You can make excuses for the first one (Because of that) and Super was a masterpiece, but this one is just... boring. Fighting primely metroids is a good concept, but falls flat the moment you have to defeat more than one of each class, the second time onwards there's no surprise or challenge, is just another number needed to progress. Also, this game would be 10 times better with a map, because good luck trying to understand what to do if you stop playing for a couple of days
