Sonic Generations

To get this you clearly have to get S rank in seven of the 18 acts. You can get this by getting seven in Classic or Modern, or a mix of the two.

Getting S rank isn't really that hard, for one you can't die. As long as you don't die and finish with a reasonable time, you'll get it. If you are worried or having trouble try to collect as many rings and kill as many enemies along the way.

Also For planet whisp I finish with a time of six minutes and a half minutes and got S so don't be worried about the time on this level.

Blazing Meteor - 30G (Original Achievement)

Difficulty: 3/10

To get this Achievement, you must get an S Rank on 7 Acts in the game.

To get an S Rank, you MUST NOT DIE. That is the main key to this as well as getting to the goal as fast as possible.

I recommend two ways to do this.

1. Go through the levels and get a feel for them. once you know what you're up against, or once you've found enough shortcuts to feel confident, go for it.

2. Believe it or not, I actually got most of my S Ranks while going for my Red Star Rings. I watched SadFaceGaming on Youtube and ran to where they were, getting each Red Star Ring, and pausing the game when I watched to see the next RSR's location. Doing this will force you to move faster than you think your going, and take shortcuts you probably didnt know about, making your S Rank easy. (Just remember to pause between RSR's!)
