The Opening Act
Simply finish the first stage of the game.
All Stages Cleared!
Finish the game!
Greased Lightning
Okay, this is one can be hard for new / unexperienced Sonic players.You have to finish Green Hill Act 1 in under a minute
Ive linked a video so you can watch the best route to take to easily burn through this achievement. It mostly consist of staying on the higher route of the level and spindashing a couple of times.
Bright Star - Big Bang
These achievements consist on getting S Rank on every Level. Wich can be tricky, my best advice would be to learn the level layouts as much as you since to get S Rank you have to complete the level in a low amount of time without dying once. Dont give up you got this!
Trickstar
This one is pretty easy to complete, the best way to do it is to go to Rooftop Run Act 2 and when you reach the top of the clock just spam the tricks, you should have enough time to do 7.
Eradicator
This achievement is also fairly simple, you might complete it without even wanting to, just defeat 100 enemies! (You might just do it in your normal / first playthrough).
Ring King
Complete Green Hill Act 1 without dropping any rings that you've collected. If you're having difficulties with this achievement why not buy a shield from the store?:)
Action Hero
Perform all of Sonic's moves in Act 2.
Bonds of Friendships
Complete all Challenge Acts featuring Sonic's friends. If im correct theres 2 of those for each zones, one as act 1 and the other as act 2. If you're having any difficulties for a specific one don't hesitate to let me know in the comments!
Walkie Talkie
This one is easily do-able after completing the game, you can just run through the hub talking to everyone on your way:)
Join The Ranks
Upload any time trial or score to online ranking.
A 30-Second Test
Just pick any level of your choice and do the 30 second test, I'd recommend Green Hill.
Mad Skillz
This one is easier to complete after completing the game and doing all missions level since you unlock skills in the shop for doing so, by that time you'll have enough point to buy the whole shop.
(Hedge)Hogging It All Up!
Get all collectibles, again for this achievement you will need to have collected all red rings AND all done all missions sincee you get rewards from completing them.
Time Attacker
Okay this one is not hard but more of a long to get, you have to replay all levels in the ranking Attack Mode,] its a good thing you dont actually need to have a good time on each level,so go at your paste:)
Red Ring Collector
Okay this one can be a b*tch to complete, but if you want to 100% completion you'll sadly have to gothrough it. Ive linked a guide to help you find them all !
https://cs2bus.com/sharedfiles/filedetails/?id=1692592536
Halfway Point & Mission Accomplished!
Clear all Missions! Dont forget to pick up your reward after completing each one!
Zones Restored!
Fairly easy one once again, you'll probably have this one done by the time youve completed the games ince its all about restoring each zones.
Treasure Hunter
Collect all 7 Chaos Emeralds. Chances are, if you completed the game, you have this achievement.
Shadow Boxing
Beat the sh*t out of shadow, he probably deserves it.
Silver Got Served
ITS NO USE, ITS NO USE, ITS NO USE.
Scrap Metal
If you get 3 of those you can probably get a Reclaimed Metal.
Perfect Punisher
Defeat Chaos! If you have difficulties with this one, just be glad you aren't playing Sonic Adventure 1.
Boom Boom Dragoon
This boss can be a tad hard if you're not sure what to do, here's a video in case ;)
Sunny Side Up
Deafeat Death Egg Robot.
Cant Touch This
Literally the hardest achievement you'll have for this game, it requires you to beat the final boss without getting hit, NOTE that only Time Eater's attack will make you fail the achievement, you can get hit by debris with no problem.
A Quick Breather
Get the Red Star Ring atop the highest spot in ROOFTOP RUN Act 2 and reached the goal.
Color Power!
Get the Red Star Ring by using an Orange Wisp in PLANET WISP Act 2 and reached the goal.
SuperSonic!
Clear any regular stage as Super Sonic.
Walk on Air
Clear SKY SANCTUARY Act 1 without falling and losing a life. Take your time and dont try to rush it.
Demolition Derby
Super SImple; Load into City Escape and hit everything you see on your path.
Secret Sleuth
Get the Red Star Ring located in the hidden room in SEASIDE HILL Act 1 and reached the goal.
Look Both Ways
Reach the goal in CRISIS CITY Act 2 without being hit by a tornado-carried cars or rocks.
Walk on Water
Clear CHEMICAL PLANT Act 2 without entering the water. There is a specif path to follow to easily complete this one:
Jump for Joy!
Find the spring hidden in GREEN HILL Act 1 and reached the goal with a Red Star Ring.It requires staying on the highest part of Green Hill, when you reach the part where you jump on a BuzzBomber on a spring you should see another BuzzBomber with a yellow spring in a Palmtree, thast your goal, jump on the BuzzBomber and follow up the spring to reach that Ring:)
The Byway or the Highway
Get the Red Star Ring located on the shortcut route in SPEED HIGHWAY Act 2 and reached the goal.
Outro!
Thank you for reading this guide and hopefully it helped you get those pesky achievements in Sonic Generations, if you have any questions or feedback do not hesitate as this is my first guide.
Stay way past cool:)

The Eradicator achievement is still not popping up for me
Press Infinity 18 Apr @ 8:53pm 
Every time I try to load the time attacker the game crashes... I tried loading the 30 second time trial mode fist but that didn't help. Please someone tell me it's still possible to get the achievement.
Zach 11 Apr @ 11:37pm 
The achievement Eradicator won't appear for me? Anyone else having this issue?
Banake 5 Apr @ 6:28pm 
Thanks. \o
Banake 5 Apr @ 9:40am 
Yeah, I got "Join The Ranks", "A 30-Second Test" and "Time Attacker" yesterday. Its kind of annoying that it kept crashing, but it was possible.
FenecK 5 Jan @ 7:25am 
Can also confirm that "Time Attacker" is still possible to get. :SuperstarsSonicFace:

Its a little glitchy, you don't see your times in the list mostly, and sometimes it crashes, you also need to load the 30 second time trial mode first before Time Attacker mode to avoid a guaranteed crash, but it is possible to get currently.
FenecK 27 Dec, 2024 @ 10:13am 
Can confirm that as of today you can still get the "Join The Ranks" & "A 30-Second Test" achievements.
Natekyu 12 Nov, 2024 @ 5:37pm
