Introduction
Welcome to Sonic the Hedgehog 4: Episode 2. This game has 12 achievements for 200 and is the second Episode in the Sonic 4 saga. You will be fighting against Dr. Eggman once again, but this time he’s brought Metal Sonic with him. If you own the first Episode then you get a free "DLC" called “Episode Metal” in which you play as Metal Sonic in four acts from zones of the first game. It serves as a Prologue of sorts to Episode 2. To play Episode Metal go to the level select screen and press to start playing it.
Step 1: Main Game
Before I start, make sure you get every Red Star Ring in every non-boss Act. There is one ring for every act. Note that you should have 50 rings before you get to the goal post so you can enter the Special Stage though the giant ring. In the Special Stages you can pause and reset the stage if you are having trouble (Provided you haven't passed a checkpoint without enough rings already). Also of note is that the earliest Act you can have Super Sonic in is Oil Desert Zone Act 2. Remember to press after every Act so you do not go the the World Map once you start the first Zone.
Once the first Act starts beat the stage in under a minute while jumping into the giant ring to get the The Adventure Begins and Proof of Speed achievements. While in the first Special Stage, gather all the rings in it (There are 314 rings) to unlock Ring Collector. Once you get to the third Act you can press while on the ground to activate the rolling combo and get the Rolling Combo! achievement.
Make your way to the end of Oil Desert Zone Act 1 and jump through the big ring. Get the last Chaos Emerald here to get the All Chaos Emeralds Found! achievement. From now on, deal the last hit to every upcoming boss in each zone’s Boss Act as Super Sonic (You also need to finish Death Egg mk.II Zone Act 1 as Super Sonic). From here make your way to Sky Fortress Zone Act 1 and beat Metal Sonic for the Metal Sonic Falls achievement.
Once you get to Death Egg mk.II Zone Act 1 find the last Red Star Ring and beat the level. Once you get to the Boss Act, beat the boss to get the All Red Star Rings Found!, Endurance Race, and All Stages Cleared!achievements. Enjoy the ending (Endurance Race does not unlock in Co-Op).
Step 2: Super Sonic
Since you have Super Sonic now and have beaten the zone bosses of Oil Desert, Sky Fortress, and Death Egg mk.II, you just need to beat the bosses of Sylvania Castle Zone and White Park Zone in their Boss Acts. Doing so with net you the A Golden Wave achievement. Go to the bosses through the level select.
Step 3: Playing as Tails
To play as Tails go the main menu and select “Multiplayer”. Choose your preference and pick a level and an Act. You will be prompted to choose who you want to play as. Pick Tails using and then beat an Act. Upload your score/time afterwards to get the Tag Partner achievement. Continue beating the act over and over until you have played with Tails 50 times. This will unlock the I Love Tails achievement (I highly suggest playing as Tails 50 times in Local Co-Op as it doesn't seem to work online).
Step 4: Miss Anything?
If you missed any achievements then head back to the level select and do what you need done. None of the achievements are missable because of the level select.
Conclusion
Sonic 4: Episode 2 greatly improves upon the first Episode in pretty much every way. The 200 is pretty much like the first Episode and shouldn’t be that hard besides a few Special Stages. Good luck!
