Possibly the greatest pinball game ever created!
This is not only a game where you hit a ball around with flippers, but you can gather high powered weapons and even stand up and shoot enemies with the collected powerups! The reason I labeled this game as "hard" was because of the difficulty of many of the sublevels and also the Bosses you have to defeat. yes, thats right I said Bosses!
Basicaly you have to collect the 12 artifact pieces by completing missions throughout the game. The missions consist of destroying Metroids that fly around the screen, bombing tricepts, shooting shreekbats & beetles, running over burrowers and even wall jumping. As your rolling around and trying to prevent Samus from falling through to the bottom of the screen (like in every pinball game) you can open different bonuses which include force fields and multi-balls. There are opportunities to advance to different levels in order to defeat Boss characters and even the Metroid Prime itself. You can continue playing the different levels but once you collect all 12 artifacts you can advance to the Temple level where Ridley attacks you as you try to hit Samus into 12 different columns. Once this is accomplished you can once again advance to the Impact Crater to fight another Boss followed by the Metroid Prime. Defeating the Prime ends the storyline but the game continues and basically never ends untill you run out of balls. The fun factor is what makes this game so addicting. Because a regular pinball game can be boring but because of all the side missions and enemies that attack you this puts this game well above and beyond all others. Plus you can be playing for hours and not even realize it.
Thank you Nintendo for making this incredable game and please feel free to make more pinball games based on exclusive characters.
