Simply Rotastic - 5
Do the Rotastic trick.
This should be your first achievement in the game and you will get it after the first few levels, even if you don't go for it. Just hang onto one of the poles and spin around in a circle, until you fill up the blue bar, now press
to let go at the right moment so you fly towards the side of another pole. Press
again and you will spin around the second pole without losing any speed. Finally get back to the first pole to finish the maneuver (A line will appear looking like the one in the achievement picture). This trick will be helpful in getting gold on every stage.
The Hero's Debut - 5
Complete 5 levels in campaign mode.
Easy. Just start the first level of world 1 and keep playing one stage after another. When you get at least a copper helmet for beating the 5th level, you'll unlock the achievement.
Diamond necklace - 15
Get 5 diamond helmets in campaign mode.
I would suggest stages, in which the games teaches you a new trick. These are always easy to master and also quick to finish. If you don't get platinum, just press
to try again.
Some simple stages I got platinum on:
1-1 / 1-2 / 1-4 / 1-5 / 3-6 / 4-2
Aspiring Hero - 5
Unlock access to World 3 in campaign mode.
Refer to A New King is Crowned
Hero on the Rise - 10
Unlock access to World 5 in campaign mode.
Refer to A New King is Crowned
A New King is Crowned - 25
Unlock access to World 7 in campaign mode.
You need to get 120 helmets to unlock world 7. Each helmet you unlock in a stage counts towards it. So if you beat a level with a platinum helmet, you add 4 to your total amount.
The Jeweler - 10
Collect 5,000 jewels.
You should get this before managing to get every gold helmet in the game. Just play through every stage and by the end of world 7, you should have unlocked this achievement.
I don't know wether the jewels you earn in multiplayer count towards the total amount.
Mini copper - 30
Get all copper helmets in campaign mode.
Refer to This is No Lifestic!.
Just complete every stage in each world. By completing a level, you'll automatically get a copper helmet.
This is No Lifestic! - 50
Get all gold helmets in campaign mode.
This will definitely your last achievement in the game. You need to get a gold helmet on every stage of each world. Platinum isn't a requirement but there are still some levels that are really hard to get anything better than copper. Keep at it, learn the tricks, master the physics and you eventually can add another hard achievement to your collection.
The Butcher - 20
Kill 10 enemies in a row without losing a life during a multiplayer game.
Just plug in a second controller and turn off the AI. Choose the first level and with your main profile get to one of the poles and start swinging around it in a close circle. Now press
on the second controller, when the icon at the top is above your player. Press
again to latch onto the same pole as soon as possible, so your character will cut the rope. Repeat 9 more times without messing up and the achievement is yours.
The Ninja - 10
Kill 3 enemies in 4 seconds in a multiplayer game.
This one is a little bit trickier but also easy to get. I got it during my second game. Just play by yourself with 3 AI enemies and choose the first map. To kill an enemy you need to cut their rope, so they fall to their death. Just keep swinging from pole to pole, when you see another character interacting with it. try to get as close as you can. Only do this on the lower 3 poles, because the enemies still can rescue themselves, if they fall from one of the upper poles.
The Socialite - 15
Play 20 multiplayer games.
Just play against one AI enemy, start a game (50 jewels) on a map and either put the controller down and let the enemy win or try to gather as much jewels as possible. Just start a new match after the last one ends and you should have played 20 total games in about half an hour.
