For this achievement, you will need to collect all the pellets in one combo. You will need a well levelled character.

You'll want to start with the manual pellets in front of you from the start, and then grind over the halfpipe. Make sure to manual out of the grind, collecting the ground pellet, and shooting yourself up the quarter pipe high enough to connect with the grind. Continue the grind to the lower level, and jump off to the left side aiming for the manual pellet (2nd room now). You will need a lot of speed here, but if done correctly, hold the manual up the quarter pipe, jumping to connecting with the grind on the higher pipes. Now grind around the corners, jumping off at the red pellet and finishing with the final 4 manual pellets.

Having your stats maxed will obviously help. I found that you need to ollie onto the first rail, and go straight into a manual off of it to maintain enough speed for the rest of the run.

There's also a glitch that might make it easier for you if you're having trouble. The last 4 manual pellets don't have to be collected as part of the combo. You can bail, collect the last 4 manual pellets, and the achievement will still unlock.

I have found a technique that takes almost all of the difficulty out of this achievement for those who are struggling to collect all the pellets in one combo.

The concept is after having collected every pellet you MUST have LANDED only one combo. So if you bail and never land a trick until you collect the last pellet, you can break the run into as many segments as you're comfortable with.

I recommend using MAKA's combo line as a guide. It shows the best route to collect the pellets on one run.

I personally found it best to break the line into three combos: The first section stops right after you break the glass into the second room and collect the green pellet on the ground, go up the ramp and hold a grab move until you bail.

The second section starts from the high rail in this room until you collect the red pellet after breaking through the glass a second time. Again hold a grab move to bail.

Now you're down to those last four green pellets, collect them in one manual perform a flip trick and the achievement will unlock.

***Note: if you just land the manual, it will not unlock.***

Let me know if this helps or if I need to explain anything clearer.

Maka91's guide is pretty sound but after far too many attempts at this son of a bitch, here's my guide.

1. Max out your stats. Seriously, this is balls hard. Don't make it harder for yourself.

2. I used the analog stick as the steering control on the d-pad is gash (even the new twisting, adjustable ones).

3. When going for manuals I throw in a few extra moves on the analog stick (a manual requires up/down but I go u/d/u/d or whatever so that there's no doubt).

4. Try to leave any grind or manual while in the middle of the balance meter. It really helps.

5. If you miss a pellet (usually that floor pellet in the second area) but are still in your combo, keep going. You won't get the achv in that run but you'll get some bites at those final four pellets and they are a bitch to steer through when your balance meter is wobbling all over the place.

I'll use CAPS for any bits I consider to be quite important.

For the first section, speed is everything. Get a jump onto the ramp and land in a manual. Build up speed right through the first pellets. Jump into a grind over the half pipe.

DON'T JUMP OFF THAT GRIND. Drop off naturally and go into a manual. You need speed to get up to that high grind rail. When jumping up I POINT VERY SLIGHTLY to the left so that I don't have too much speed on the rail.

Ride the rail but JUMP OFF AS SOON AS YOU HIT the last yellow pellet, making sure to catch the red in the process. In mid-air push the stick u/d to catch a manual (you should just land in a grind but sometimes you don't and will have to ride the manual onto the grind).

IMPORTANT: while grabbing to two grind pellets start pushing left (this will unbalance you a lot but don't worry). Jump out as soon as you get them and land in a manual. Steer through the solitary floor pellet (this bit is a pain in the arse) and go up the quarterpipe to hit the high rail (above the big door to the hidden outside area).

WHEN HEADING UP TO THAT RAIL HOLD STICK RIGHT!!!!!! Land in a grind, holding that stick right will balance you as your grind meter will be really loaded left at this point thanks to previously jumping off of that earlier grind (the 'don't worry' bit)

Hold down Y as you drop off the high rail. DO NOT JUMP!!!

Ride the low grind around the corner. As soon as you hit the final grind pellet you need to jump left to catch the last red pellet. I always do this with a kickflip as it seems to stop me overturning.

LAND IN A MANUAL! Hopefully you won't have too much speed. Hit the first of the four pellets (32) and turn right towards the next (33). Do not try to ride straight through number 33 but rather trying to arc through it as the final two are in a curved line from it.

LAND SAFELY! I didn't and the achv didn't pop that go. Seriously I don't know how I didn't kick my television in its imaginary electronic balls at that point.

The other solutions are really good but I like to mention one last thing. If you collected all pellets in one combo, be sure to continue in a manual a little longer because if you land just after you collected the last one, you will not unlock the achievement. It happened to me twice and it's really frustrating so maybe it's better you know.

If you downvote, let me know why but if I can help one other gamer with this 'solution', I'm glad I helped someone out.

This achievement isn't as hard as it seems. Here are few tips that i think might be useful.
1. I did this on d-pad, but i guess everyone is comfortable with what's best for them. I think it's easier to go into manual and balance while turning with d-pad.
2. Wait to the very last moment and start a manual for the first pelets(i used nose manual)
3. Do a little olie and grind over the halfpipe.
4. Do not jump of, just while griding tap 'up-down' and it should go into manual.
5. Before reaching quater pipe adjust your manual a bit(tilt it to the other side then the meter is going)
6. Jump on a rail high up.
7. Let the balance meter go about 1/3 to the right while grinding(you might tap it to the left and then to the right)
8. Jump collecting red pellet and after you collected it turn skater 90 degrees
9. Grind over 2 yellow pellets and jump to the left(this is tricky part because while jumping to the left your balance would probably go to the left, this is why you let it go 1/3 to the right while you was high on rail)
10. This is the hardest part. Manual over green pellet and try to do it in straight line from where you jumped of to the connection of gray and brown quarterpipe. Also adjust balance a little bit
11. Jump to the rail high above and cross your imaginary fingers because reaching it is hard.
12. Grind through yellow pellets and do not jump down, let it fall. While falling you can do 90 degree turn to make sure you hit the grind, but do not turn before jumping, do it while you're in air
13. Now just grind and keep balance
14. Jump off as soon as you get last yellow pellet
15. Manual on a green pellet and keep going inside halfpipe while maintaining balance.
16. If you're lucky and have some skill you should manual all the way to the last pellet. If not don't worry. I bailed 3 times before last pellet, then when i tried again and got there for the 4th time i bailed again but this time instead of restarting i just waited till the skater got up and did a manual to the last pellet. Achievement still popped up.

I hope this helps :D
