How do you get the grandmaster galaxy in super Mario galaxy 2?

Answer 1

what you have to do is complete super Mario galaxy with 120 stars, then go to rosalina and speak to her. She will ask you do you want to go to the center of the universe. click yes and go there. Once you have beat bowser, after all of the credits, a message will appear saying you can now play as luigi. then, go to the main menu and press a and b simultaniousy. then go on to the file you've got 120 stars on. it will have Mario AND luigi on there. Just click on who you want to play as. If you want grand finale galaxy, complete it with 120 luigi stars and go back to the center of the universe. click yes and go on it and complete it. Once again, when you beat bowser and the credits have gone, there will be a message saying you can go on grand finale galaxy. Go to the main menu and go to the file where you have got both Mario and luigi playable and go on it. Once you're on it, go to the planet of trials and grand finale galaxy will be on the back of it. ( It will have that on both Mario and luigi).

Answer 2

Okay, you have to understand that the following can only be done by the BEST platform gamers. The first half of getting grandmaster galaxy is completing the game. Easy enough. The sencond half of unlocking it is getting all the comet medals. That isn't too difficult. For pros anyway. Now the third part is getting EVERY SINGLE GOLD STAR! That is highly difficult. Even for the pros. Only Master Platform Gamers (MPGs) can get this done easily. Thus the name. After that, defeat the last level one more time (Final Battle) and after you win, there will be a story about green comets. The final step to unlocking. Green comets are scattered every where. To unlock grand master galaxy, you must find them all. They are hidden in each level. Only MPGs know the secret to finding them. I'll let you readers in on the secret. First, shadows. Sometimes you will see spinning shadows on the ground. Use the camera to see what's up there, or find a way up. Second, glowing light. You will always see glowing light out of the corner of your eye if it's nearby. Thirdly, the sound. That glistening sound will get louder the closer you are to it. It's like a game of hot and cold. If you can't find it, Use the camera to search the area you hear the noise. Look all around. The hardest to get are the second green stars in both Fluzzard levels. Second, the last green star in Boo Moon Galaxy. The only way to get it is by getting to the end of that part where you have to ride on those angry faced things. When you get to the launch star though, don't get on it. Instead, long jump to another platform even harder to keep up with. MPGs even have trouble with this, first finding it, then having to keep up with the platform not knowing it's movements. It is almost impossible to complete without dying at least once.

After you get Grandmaster Galaxy, your probably going to want to know how to get the last star. You have to complete the level with the comet medal, and have 9999 star bits in the bank. I'm not joking. I haven't completed that level because they make the level harder and you only have ONE LIFE! If you get to the end though, i hear you get to talk to rosalina and she gives you the final star. I don't know if there are more levels after that, but after that long experience, you'll probably not even want to try.

Good luck.
