Good but nothing much because the concept is similar and the space pirates are not too much hard even though in phazon mines you can encounter more space pirates for a minute to minute the story is not much because this tallon IV is a home base for the Chozo so the chozo is extint then automatically in our mind will think that the chozo weapons can only be obtained here so you can get your powerups you have lost on the frigate orpheon and there are some poweups alone is not found in any of the game such as boost ball,phazon suit which gives you full immune to blue phazon and charge combos like wave buster super missile flame thrower ice spreader and space jump boots although you see this is every metroid game except metroid prime federation force and metroid prime hunters and metroid prime pinball but in metroid prime series the space jump can only give two jumps and there is no screw attack actually is was to be kept but it had More bugs and there is not much time it make this correct and there was kraid they had planned to include kraid as a boss in phazon mines and there is no time left so he was not included and the gamecube controllers were not ment to made for a first person shooter games but the contrllers are very easy to a season player but it is very hard for newcomers and i wish metroid prime 4 should be like metroid prime 2 echoes and i complete at a rate of 100% and if you need to play a metroid game in a 3 d version then play this in the end i dont want to say this as a bad game but the controller is a problem
