Introduction
Welcome to the Sonic Generations Achievement Guide! Sonic Generations features both Classic and Modern Sonic to play as. Each Zone has two acts. In Act 1 you play as Classic Sonic which plays just like Genesis Sonic Games and Act 2 you play as Modern Sonic which plays like the newer Sonic Games. This game has a total of 49achievements for 1000 . The majority of these achievements are not difficult, but some will require patience. So just enjoy playing the game and have fun!

The Zone Restored achievements and Eradicator achievements are slightly glitchy. For some people they don't unlock when they should. Unfortunately, if this happens to you the only way to get the achievements is to delete your save file and start the game over.

Step 1: Beat the Story
Just have fun playing the game! You will earn the 18 storyline achievements for 365 and  the following 3 achievements while playing the game normally:

  • Eradicator
  • Action Hero
  • Walkie Talkie

Note: To earn the Walkie Talkie achievement, talked to all of sonic friends after Restoring Planet Wisp

Step 2: Complete the Challenges
Once you beat the Final Boss, go back and complete all the challenges. There are 45 for Classic Sonic and 45 for Modern Sonic. When you beat a challenge collect the artwork or song, by hitting the bell and touching the music note. You will unlock the following 3 achievements for 70 :

  • Bonds of Friendship
  • Halfway Point
  • Mission Accomplished!

Step 3: Collecting the Red Rings
After you finish all challenges, go back to each stage and collect all five red rings in each stage. Once you collect all the Red Rings you should have every collectible. At this Point you should have enough Points to buy every Skill from the shop to unlock the Mad Skillz achievement.

While going for the Jumping for Joy achievement, I would suggest equipping the Supersonic Skill Set to classic Sonic, and finishing the level as Supersonic so you can earned the Supersonic! achievement too.  You will earn the following 9 achievements for 190

  • Red Ring Collector
  • Mad Skillz
  • (Hedge)Hogging it All Up!
  • Supersonic!
  • Jump for Joy!
  • The Byway or the Highway
  • Secret Sleuth
  • A Quick Breather
  • Color Power!

Step 4: Ranking Attack
At the Main Menu, go to Xbox live and go to 30 Second Trail, complete one to get an easy achievement. Next go to Ranking Attack, and set a time in every stage for both Classic Sonic and Modern Sonic.

You will unlock Join the Ranks, A 30-Second Test, and Time Attacker!

Step 5: S-Ranks/Level Specific achievements
Now will be the time to get any level Specific achievement you are missing, S-Rank any stages you haven't done yet and beat the Final Boss without getting hit. Refer to the guide below for help and you'll earn your final 13 achievements and 270 .

Conclusion
If you've followed the guide and roadmap to this point, you should have the full 1000 in Sonic Generations. Congratulations!
