Before anything, I want to thank Gamepro011, itsPersonnal, Kurect (a.k.a. Crydio), Sonicspeedruner and mapler90210 for all the help with strats and time savers during the run. I also want to thank all of the TSC (The Sonic Center) users, the TASVideos community, my Twitch followers and my Youtube subscribers for all the support! Thank you very much, this run wouldn't be possible without it!

Tricks used in this movie:
-Full speed spindashes: I found out that alternating between the buttons B and X while spindashing to break the previous spindash is faster, and doing it everywhere saves many frames! I also watched the speed address to be sure that I got the full speed quickly in the whole TAS.
-Spindash hover: By holding A while charging a spindash that goes towards mid-air and continue holding A, you can extend your spindash distance and hover for some seconds, so you can reach places that are far faster than doing a jump right after the spindash.
-Jump dash: By pressing B right after doing a homing attack (pressing A in the air), you break the homing attack and get a stronger foward dash, increasing your speed.
-Wall clip: A spindash can go through a joint of two walls depending on the angle of the wall, your angle, position and speed. Actually, most of the joints lower than 90° can be clipped. However, many of the out of bounds clips used in the movie aren't done like that. They're done by exploiting false walls to go through them and skip a portion of the level.
-Booster glitch: This glitch is only used in Emerald Coast, and it consists in breaking the spindash right before touching a launch pad (booster). If done right, you'll knock the booster like if it was a wall, but you'll still be launched by the booster. This makes the speed given by the booster extends for the "knocked out" animation and to avoid getting so much height, seeing that going in the air is slower than spindashing on the ground.
As you can see, many levels, such as Ice Cap, Twinkle Park, Red Mountain, Sky Deck and Final Egg, had some huge route changes, but I think that they're all self-explainable, as they don't use any trick that wasn't told before.
Suggested Screenshots (by VI Number): 10783 | 25466 | 46061 | 79850

Nahoc: claiming for judging!
Nahoc: Accepting! This movie is just too good; great optimization, great audience response... gotta go fast!
Ilari: RGamma is going to handle this (in a few days)
Nahoc: changed movie file; now the re-record count is set to "unknown".

The driving at the start of Twinkle Park was hilarious. Also can't believe how much you broke Lost World.

So, how bad will Tails's story be broken? I know it's problematic already but I want to see a TAS that destroys it. Also, Twinkle park, was the YES. Nothing I have seen was so abusive of a game's design.

A strong contender being TAS of the year. Easy yes vote. I also recommend a star. Although Itspersonnal's upcoming Sonic run could also be a good contender. Although that depends on when/if he finishes it. Anyways, very glad you finally submitted this. I look forward to your next run. Maybe you and itspersonnal should work on his run? :P

Why the apparent apathy in Sky Chase 2? It wasn't all-out scoring as 1 was, nor was it pacifist-except-the-final-cannon nor was the end score a particularly notable number. What was the aim of that one, if anything at all?

jlun2: there are kill planes that will cause you to fall off the map, but they're generous enough to enable you to get really far away from the map without failing. In particular, I've seen a video of someone doing the last portion of Windy Valley unassisted, after having memorized the positions of the kill planes with a cheat code that draws them. That said, I have no idea how Ice Cap worked.

Just looked at that part again. Why did the timer suddenly gained 10 seconds as soon as sonic reached the ground?

The timer must have fixed itself after being frozen

By default, the objective in each of Sonic's levels is to step on top of a capsule to free some small animals inside. In story mode on the first run through, some of those are replaced with story-relevant objectives, such as getting to the wreckage of Tails's plane, or grabbing a Chaos Emerald. These end conditions are more generous than normal (you can hit them on any side to end the level, instead of just the top, and you don't have to go through the button-press animation with the fraction of a second it adds), but the game also tracks your best time in each level, and they didn't want to create a scenario where the only way you can properly speedrun those levels under ideal conditions was with your first run-through on a brand new save file for each of those levels. So instead, they overcompensate by adding 10 seconds to the final time on each first-run level that has a more generous goal object. Obviously, this achieves the exact opposite result: now you can't properly speedrun those levels on the first playthrough, but they find this acceptable since you can revisit the level at any time, as often as you want (either in adventure mode again, or from the trial menu), and it will have the more standard capsule at the end thereafter. Oddly, the same isn't true of bosses: there are some bosses where the timer doesn't start until after the introductory text finishes, but only on the first run (in fact, only on the first life of that run, so don't dare select Restart from the pause menu or you've missed your chance). There is no corresponding 10-second runoff at the end of the affected bosses, so those speedruns must be done during the one opportunity you get to fight those bosses in story mode, at least if you want your time to be anywhere near optimal. Then again, the game does not track individual boss records, just a "boss gauntlet" mode that can only be chosen from the trial menu and that refuses to acknowledge any times that were set anywhere else, so they might have figured there was no permanent record to worry about there.

Beautiful, I am definitely going to have to watch this again to pick out more of the detail of the speedrun. I've been hoping for a 3D sonic TAS like this for a while and this delivers everything I wanted. Yes vote. Good luck with future SA:DX and SA2B TASes, to everyone who is planning them :)

It won't be so broken as Sonic's, as there's no spindash. But there are some interesting clips and skips!

Well, I actually aimed to get the perfect score in SC1, as there wouldn't need so much work. But in SC2, it would be very time consuming to do that, and it wouldn't make the movie faster, you just need to destroy the final cannon in the frame it closes.

The game doesn't check if you're OoB, but there are some kill planes that can make you die in OoB, mostly below the ground. You can notice that I evaded kill planes in parts like in the skip after the mirror room in Lost World, and after the elevator clip in Final Egg.

Brilliant run. On top off all the other sweet things people have pointed out I am glad that a couple of neat tricks were found to show off in the Egg Viper fight. God speed with the Tails sequel.

Why did you change camera settings in the last level? As for Sky Chase 2, I thought you were going to go pacifist run to contrast "everything must die" in the first one from the first one. Very minor problem. Solid yes for entertainment.

Me I want to see a TAS of each character... especially Big the Cat. Would be funny. PS: Yes vote. I hope to see more of your work, it's simply amazing!

I wonder what a glitchless run would be like...
Why, oh, why do I even <i>try</i> to understand my own species?
