This can be done solo or with another person. Simply pick a song and choose Dance Battle. You can play the same song 10 times if you'd like. Difficulty and score don't affect this achievement.

Freestyle photos are taken during the freestyle sections of songs, and at random times during certain moves. This should unlock during your natural progression of the game. It will take around 50 songs.

Once you turn on Workout Mode (by selecting a song in Perform It! Mode and then choosing to turn on Workout Mode), it will remain on. After each song, you will get a summary that includes calories burned and total time played. Once you reach 20 minutes of time played, this achievement will unlock.

To turn on Workout Mode, go into Perform It! Mode and select Workout Mode at the bottom. This achievement is cumulative and can be done in multiple sittings. The higher your weight the faster the calorie counter will increase, so if you want to speed up this achievement set your weight to 999lbs.

Get 10 "Flawless" ratings in a row on any song. You will likely get this achievement early, during repetitive moves on Easy, such as the Step Sides/Step Side and Claps on Poker Face.

There are eight human characters. ELIOT the robot does not count toward this achievement. If you play down the list, you will achieve this by the song "Dip It Low". Leave the dancer selected as Song Default, that way you unlock each character while playing down the list, and will unlock this achievement by the time you finish every song.

This one can be tough depending on your skill but it can be done on any difficulty so easy is recommended. You will likely need to run through a song a few times until you know it by heart. This achievement includes getting a "Flawless Freestyle" and a "Flawless Finish." This will really be a personal preference, depending on what moves you feel most comfortable with. To practice each move, you can play the song in Break It Down mode. If you get a diamond on a move, that's the equivalent of a flawless.

Poker Face is a popular choice since it's the first song, but I always seem to have problems with the "Select" move, and a lot of people have problems with "Whatever." I find Funkytown is much easier, just because there aren't any moves that require leg movement. It's basically all arms. Hey Mami is the song I got this achievement on.

NOTE: the achievement description is deceptive here. Simply getting a "Flawless" rating on every move will not suffice. If one of your body parts turns red, but you still get a "Flawless" rating, this will still void the achievement. You really have to do every move perfectly otherwise the achievement won't unlock.

If you're playing Dance Battle with a second person, have them join you in front of the camera during the freestyle section. If you don't have a second person, an office chair or large jacket can be used to trick the sensor into thinking there are two people.

It takes one or two songs to rank up initially, depending on how well you do. After each song, on the review screen, in the middle of the screen your bar will fill up. It shows your progress toward your next rank.

NOTE: you can only rank up in Perform It! Mode. Break It Down and Dance Battle do not increase your rank.

Bonus content includes the following:

-Unlock every character's second outfit, including ELIOT's
-Unlock every character
-Unlock every venue

You will unlock every character and venue when you play through Perform It! mode, completing each challenge. You unlock each human character's outfit by earning 25 stars while playing as them. You unlock ELIOT's second outfit by reaching Rank 1.

There are eight human characters in the game. You unlock their second outfit by obtaining 25 stars while playing as that dancer. ELIOT the robot's outfit is not required for this achievement.

Can be done on any difficulty. You should be getting this on your first song within a couple attempts. Poker Face is the easiest song and shouldn't take more than one or two tries.

This can be done solo or with two people. If you've already played the songs in Perform It! mode, you should have no problem getting 5 stars in Dance Battle mode.

This achievement unlocks after getting 5 stars on Teach Me How To Jerk by Audio Push.

A few important tips:

1) The difference between the Slide Jerk and the Low Jerk, aside from the time you spend leaning to each side, is in arm placement as well. The Slide Jerk has your arms as if you were pumping from your chest. The Low Jerk has your arms out practically in front of your body as if you're ready to check someone.
2) The Knee Down Down moves are NOT symmetrical! It's going to be natural to assume they are and to mirror the move, but this will cause you to fail it every time. The first part, using your right arm and leg, firstly has both arm up in front of your chest. Secondly, it starts with your arm moving inward and leg moving outward. The second part, using your left arm and leg, has your right arm at your side, and starts with your arm moving outward and your leg moving inward.
3) The forward-facing Reject always starts with your right leg up and your left leg moving forward

Also, this video may help with learning to jerk and reject:

If you're following the roadmap you should have this by the time you complete the Grand Finale Challenge with 5 stars. The challenges do count toward this achievement. If you don't get this on easy, then you'll unavoidably get it when 5-starring all of the songs on hard.

See "Dance Instructor" for tips.

You will get all of these challenge achievements by getting 5 stars on each challenge. You unlock each challenge by getting at least 4 stars on each song in the group just prior to the challenge. The challenge consists of a group of moves from each song in the set. This is why the challenges are best done right after finishing each set of 4-5 songs. That way, you should be pretty familiar with all of the moves, and getting 5 stars on each challenge shouldn't be too difficult.

The Grand Finale Challenge has moves from every song in the game, so hopefully you have a good memory, otherwise it may take you a couple tries!

This includes the challenges. You can check your progress on a song by selecting it and looking at the rating next to the Perform It! option. The letter will indicate the highest difficulty, and the number of stars will indicate the rating you got. For example, if you've 5 starred a song on hard it will show H*****.

Your score dictates your star rating. Your score is higher if you can keep a good multiplier going. It counts up 1 every time you have a Flawless or Nice on a sequence. 1x is lowest, and 4x is highest. If you move a body part wrong, the wrong part will glow red on the character. For example if your feet are correct and your arms are wrong, the characters arms will glow, but his/her feet wont.

Also, make sure you keep moving during the Freestyle section. If not, you will lose your combo. You can tell if you moved enough if it says Flawless at the end of the freestyle section (instead of Nice or other). All you have to do is make sure you move the entire time to get a Flawless. Just wave your hands at the screen if you need to conserve energy.

Lastly, if you're still having a hard time, watching Youtube videos can help. Riffraff67 has a lot of songs on his channel being performed on Hard. He does a picture-in-picture, so you can see how he moves in relation to what the dance move is. Mightymecreative is also a popular Dance Central video poster.

Gold stars are one step better than 5 stars. You'll hear the same chime as when you go from 4 stars to 5, and all the stars on the radio will turn gold. The achievement will unlock at the end of the song. Unlike in the Rock Band series, gold stars can be obtained on any difficulty level. You will likely get this when going for the Pure Perfection achievement, since getting gold stars on easy requires you to pass (at least a "Nice" rating) on every move. I found the first two challenges to be easiest, since the moves they picked from each song are pretty easy ones.

See "Flying Blind."

As stated in the roadmap, your best bet is to 5-star a song on easy to unlock No Flashcards, then immediately play the song again with Flashcards turned off. Challenges count toward this achievement as well.

This achievement requirement can be deceptive. Simply getting 5 stars on a song will not suffice. You must do at least as well as your previous best for it to count. You'll know if you've got a song done toward the 10 you need if, when you select the song, there's a picture of a blue flashcard with a red line through it next to your rating on that song. So, if you get gold stars on a song with flashcards nwhen you replay without flashcards you will also need to get gold stars.

I found the first 8 songs and 2 challenges the easiest 10 to get 5 stars on without flashcards, but it's all down to personal preference.

See "Something To Prove."

Break It Down mode involves you performing each song in the game in multiple sections. You'll perform each move individually, and then a recap will require you to put a few moves together. To get 100% on a song, you must get at least a nice on each individual move (3 times, if you don't nail it the first time), and then you must get at least a nice rating on each move during each recap. During the individual moves, you should see at least a green check mark next to each move, or a diamond if you got a flawless. After the recap, you should see, for example, 19/19 moves passed 100%.

It is highly recommended to 100% every song on Easy to unlock this achievement before attempting ANY song on Hard. If you attempt a song on Hard, you must then 100% that song on Hard for it to count toward Something To Prove. The rest of the songs you've done on easy will not be affected by the one song you broke down on Hard.

Another useful trick: if you are trying an individual move and fail it twice, use your left arm after an attempt to "slow it down." This will slow the song down and give you more attempts. When you then speed it back up (the same way you slowed it down) you now have 3 more attempts to pass the move. For example, you pass the move the first time and get one green check. Then you screw up twice in a row. Slow it down with your left hand, practice a couple times, then speed it back up with your left hand. Now you have 3 more attempts to get the last two passes that you need.

See "Something To Prove."

See "Something To Prove."

Every song has a finishing move at the end. You'll have to nail the move, and you'll know you did it right if you see the blue "Flawless" pop up around your legs after the move is complete. Poker Face has the easiest finishing move, and I Know You Want Me is really simple too. If you don't get it your first try you'll surely get it during one of your many replays of each song.

There are 4 different songs with Jazz Squares in the game. Like all of the achievements below for various moves, these can be done in either Perform It! or Break It Down. You must pass them ("Nice" or better rating) in EVERY flashcard that shows up. However they don't need to all be done in the same playthrough of a song. For example, in Push It, you can pass the Jazz Square and fail the Jazz Square & I, then play the song again and do the opposite and it'll still count. The following songs contain jazz squares:

Brick House (any difficulty) - "Jazz Square"
Hey Mami (medium or hard) - "Jazz Square" and "Slow Jazz Square"
Hella Good (medium or hard) - "Jazz Square"
Push It (medium or hard) - "Jazz Square" and "Jazz Square & I"

This achievement can be done in Perform It! mode or Break It Down mode. Simply get a flawless rating on a move that involves a spin. The achievement will unlock at the end of the song, not after the move. I found the move "Tantrum" in Push It on medium or hard to be the easiest.

Examples of songs that involve spin moves:

Drop It List It's Hot on Hard
Don't Sweat The Technique on Hard
Push It on Medium

See "A Lover and a Dancer."

Note: it is suspected that the achievement description incorrectly lists & Feelabout as the dance move, when in actuality the move required is Feel About.

All of these moves can be done either in Perform It! mode, Break It Down mode during the individual move attempts, or during the recaps. You will need to get at least a "Nice" rating on the move for it to be considered passed. Some of the moves are only available in the hard mode of the song, so you will likely get these after breaking down each song on Hard, or playing each song on Hard in Perform It! mode.
