I'll start with those for two reasons. First, some of them will take a lot of time to unlock since you have to repeat a lot of moves. Most of them will unlock naturally if you go to the end of the game but not all of them since some tutorials come really late. The second reason is the fastest you master this techniques the easiest it will be for you to beat some levels and achieved high-scores.

N.B.: I'll put the screenshots of the tutorials near each of them so click on the links if necessary.
N.B2.: Perfect means that the green icon must appear to count. It's just a question of timing, pushing a stick or a button at the last time.


Anti-Grabity
Achieve a total of 600 seconds air time
You should unlock this easily in the beginning of the game.


Over the Bolts
Achieve 1,000 Perfect Landings - Tutorial
This is one of the achievement you should look out since you you'll use Manual soon enough and you won't be able to do Perfect Landing a lot from that point (well, if you want to reach High-Scores).


Too Grindy
Achieve 1,000 Perfect Grinds - Tutorial
Not much to say, it's just a question of timing. You should unlock this near the end of the game.

They Last Twice As Long
Achieve 500 Perfect Manuals - Tutorial
The trick you'll have to master to avoid breaking combos. Should come naturally as well and you can do the first 2 worlds without it but doesn't hurt to master it quickly.


Hold It (I Like the Way You Tweak It)
Achieve 500 Tweaked Grabs - Tutorial
When in air, juste push the right joystick long enough to grab your skate. The icon Tweaked should appear.


Switch Up
Achieve 500 Grind Switches - Tutorial
This tutorial appears in the last world, way way too late. It isn't necessarily clear either so: Just do a grind first. Once you're stabilized (~2 seconds), push A and move the left joytick in an other direction without releasing it.

Better Late Than Never
Achieve 500 Late Tricks - Tutorial
Another tutorial that appears too late for me. Not the easiest to pull off as it doesn't come naturally either. The blue icon "Late" should appear each time to manage to do one.


Are You Dizzy?
Achieve a total of 180,000 degrees of rotation - Tutorial
Should come naturally. When in air, just pull a trigger RT / LT to rotate.

Side Hustle

Every Trick in the Book
Perform one of every Trick
If at the end of the game, you didn't unlock this, go to menu (world map) and click on Tricktionary. You'll see the full list of what you have to do one by one. It's gonna be tedious and not fun but my advise, start with the Special Tricks, the ones you don't do a lot.


First Try
Finish a level without slamming or respawning
Should unlock naturally, got it in an early level. You just don't have to fall or respawn


Opt In Drop In
Finish any Optional level with all Perfect Grinds and Landings
Optional Levels are the Blue Triangles. Find one that's easy enough for you (dit it in The Hidden Hills for me). You can use checkpoints, you don't have to beat the level in one run.

More Than a Tourist
Fully complete a District - Looks like this
Starting near the end of World 2, you'll arrived in a zone where you have to finish 2 of 3 levels to continue. Just finish the 3 levels to unlock this trophy. There are other zones in other worlds too.

So That's How You Do It
Complete a level in one Combo
You can combine this with the two achievements below. There is a point where you'll have to do it anyway if you want to beat the high-score. If you struggle, juste try on an early level. You have to do Manuals.

Nail the Landing
Get your first Combo over 1,000,000 points
Says it all. Use all the tricks you have (especially manuals) and try to never break the combo. You can do it anywhere.


Hundreds Club
Achieve a Combo multiplier of 100 and then land in a Career level
Unlocked for me at the same time than 1,000,000 points. Rotate (with RT) a lot to increase your combo number.


I Think That's Everything
Trick, tweak a Grab, rotate 180, Grind, Late Trick and Grind Switch in one Combo
Not really hard when you know what to do. If you are having diifculties to do a late trick, start with this one so you won't waste time to fail at the end.


Spot Finder
Set a score on every Style of Gnarvana Portal level
Once you finished the game, go to the far east of the Map and enter "Gnarvana Portal". Just finish a level of each world (Sunshine Valley, Cloverbrook, Burntrock, Sketchside, Los Vulgas) to unlock the trophy.

Pro-motion
Get promoted in Leagues
Same as before but this time click on the Black Icon with a podium to enter a league. You'll be in competition with 9 others players. Finish the level (possibly with a high score) and wait for the day after. Reconnect and you should unlock the trophy.

Known Round Here
Win a League group
Exactly the same as before but this time you have to get the highest score of the group. So if your skills are low, pray that the others are worse than you. There is a good part of luck, depending on the skills of the others players in your group

Going Up
Learn about Tractor Beams
This should be the first trophy you unlock for this DLC. Just launch the Level UFO in Burntrock.

The Whole V.O.I.D.

Sums it up pretty well. The levels are hard so it'll take you a while to do this.

Treasure Hunter

In each levels, there are 3 pieces of the Map you have to collect. Most of them are not that hard to find, just check every possible route in every levels.

Side note: In the level East by West South, there is a time after the first checkpoint where you'll see a vertical Wind Zone. Soon after the horizontal Wind Zone, jump to ride on the lower path. When you enter the vertical Wind Zone, jump again. Don't use the horizontal Wind Zone to get to the top. I spend too much time on this before realising it - Picture
