This article contains a list of glitches from Sonic Adventure 2. Unless otherwise noted, all glitch names are conjectural. Many of them have not been confirmed by Sega.

List of glitches[]

32 feet per second[]

When going through the loop that leads to the building that the player runs down in City Escape, if Sonic jumps at the right moment, he will fall down the building rather than run down it. Alternatively, the player can Spin Dash while Sonic is running down to achieve the same effect.

Fall in Metal Harbor[]

This glitch can only be performed on the Dreamcast version of the game. After getting to the Goal Ring in Metal Harbor, once Sonic starts his victory pose, the player should press Y Button Dreamcast on a second controller and Sonic will slide off on his board and into the water as the level statistics pop up. He'll seemingly fall forever in the abyss.

Treadmill pillar glitch[]

This glitch can only be performed by Sonic, Tails, or Shadow. Once the player's character of choice enters the Hero Garden, they should have him jump on the white pillar up the small stairway. When they reach it and start running, Sonic, Tails or Shadow will get stuck and will keep running in place. To stop this glitch, the player can jump. This glitch cannot be performed by Knuckles or Rouge because their controls are different, and Eggman cannot perform it because he can't jump high enough to reach the pillar.

Infinite Chaos Drive/Animal use[]

Note: Also works in Sonic Adventure DX.

Probably the most famous glitch in the game, and essential to know for quick, efficient Chao raising, especially since players can only hold ten Chaos Drives and/or animals at a time. Instead of letting the Chao grab the Chaos Drive or animal off of the player character, they can trick the game by placing it directly in front of the Chao. When done properly, the Chao will absorb the Chaos Drive or animal as if the player had given it to the Chao directly, and will again be flung away from the Chao while still being interactable, allowing the player to grab the Chaos Drive or animal again to re-use it. This can be done to level up a Chao quickly, as the player does not need to keep returning to action stages to retrieve more Chaos Drives and/or animals.

Chao Lobby glitch[]

While in the Chao Lobby, the player can use any character to float above the Garden entrances. They then can jump, fly or glide towards the top of the entrances and they will notice the standing in mid-air effect. It will eventually clip the player out of bounds

Out of Bounds in the Chao Garden[]

To perform this glitch, the player should go to the Normal Chao Garden and use Sonic (or Shadow) to Homing Attack the corner on the left of the entrance to the Chao Stadium (the character should be facing the ocean). After using the homing attack some number of times, the chosen character will go through the Garden's boundaries. The screen will start to continuously shake and the player can go as far as they want. Going a certain distance will cause items and Chao to "swim" under the garden. However, going too far can possibly cause the game to crash.

If the player enters the Chao Stadium or exits the Chao Garden from the other side, then exit or return back, the game will crash, although it only happens if the respective garden's ball is obtained from the Challenge/Hero/Dark races. To avoid the game to crash in this case, the player must either enter another Chao Garden or play Chao Race/Chao Karate then exit. Afterwards, the player can come back to the Chao Garden, with no risk of the game crashing.

Rouge's wonky eyes[]

Download (4)

Rouge with wonky eyes.

Strangely, when Rouge climbs onto a wall, and then moves to the left, her pupils and irises will look distorted. This is more noticeable in the Hero Garden when she climbs onto the ledge that has a circle roof on it. When moving to the left, pausing the game will give her wonky eyes.

Glitch Chao[]

Exclusive to the Dreamcast version of Sonic Adventure 2, the Glitch Chao is the result of the game failing to write the data for the Chao's appearance, causing it to look completely messed up with growing polygons that may crash the game if they become too big. This appearance is only temporary, as once the Chao evolves, it will revert back into a normal Chao with the color it originally had.

There are two ways to create a Glitch Chao โ€” one way is by turning off the Dreamcast while the Chao is hatching from its egg (or if the game unexpectedly crashes during the hatching); the other way is to transfer any type of Chao from Sonic Adventure to here with the VMU, in which the Chao will appear glitched after hatching from the egg.

Knuckles' right ankle twists continuously[]

If the player heads to the Chao Kindergarten while holding any object from a Chao Garden and looks closely while Knuckles is walking towards the building, they will see that his right ankle is twisting continuously. This also happens when the player is controlling Knuckles in the actual Chao Kindergarten building.

Knuckles' wrist and hand rotate in an outward direction[]

To perform this glitch, the player must play as Knuckles in the Normal Chao Garden, then head to the patch of flowers to the right of the other patch (which is closest to the exit of the garden) while holding an object. If Knuckles walks into the flowers continuously, his wrist and hand will rotate in an outward direction. This can happen with either the left wrist or the right wrist, and can also happen with both wrists at the same time.

Delayed Chao jingle[]

Rarely, the jingle that plays during a certain event in the Chao Garden (stat leveling up, Hero/Dark Chao evolution, Chao dying, or when transforming into a Chaos Chao) is sometimes delayed and played later on, or occasionally does not even play at all. This glitch occurs more often in the HD version.

Dreamcast Chao Doctor Crash[]

Death-glitch-en

The problematic translation

In the original Dreamcast version of Sonic Adventure 2, should the player take a Chao after it has reincarnated to the Health Center, the doctor has a chance of telling the player how many times said Chao has reincarnated. The thing is, the message is horribly bugged, causing the game to glitch itself out. This does not happen if the game's native language is set to Japanese.

Side effects include player characters getting janky, with crashes occurring when the pop-up text outside of doors in the Chao Kindergarten appear.

Note: Attempting to save and quit while this glitch is in effect will crash the game into a blue screen and corrupt the Chao Garden save data.

The Chao Doctor's message was supposed to say something like, "Looks like this Chao transformed [number] times."

Merging characters glitch[]

In 2P Action Race, the player must get to one of the checkpoints and jump into a bottomless pit. They then should have the two characters jump off at the same time (it is recommended that one player control both characters). If close enough, when the characters arrive at the checkpoint, they will "merge" into each other's bodies. The player can have the characters die separately but must make sure to not move either character after they die.

Cannon's Core anti-piracy[]

The Dreamcast version of the game runs a disc check to make sure it is being run from an official GD-ROM rather than a copied disc. If this check fails, Dr. Eggman will fall through the floor when he starts his section of Cannon's Core, acting as the game's anti-piracy screen; this section can still be completed by navigating to the security door at the end, but players can fall out of bounds if not careful. This cannot happen on emulators, even when using a pirated copy.

Somersault glitch[]

During the first Sonic vs. Shadow character battle, if the player slightly taps the Somersault button while standing still just as Sonic/Shadow attacks them, the player's character will not perform the somersault. The hitbox for it will still activate, making the game think the character is still using the somersault. This makes the character invincible to Sonic's/Shadow's attacks for the duration of the fight.

Chao Key glitch (Sonic)[]

Downloads

Sonic as he is accessing the game's Test Room.

Note: Does not work in the Dreamcast version of the game.

To perform this glitch, the player must first go to Sonic's Crazy Gadget (either Mission 1 or Mission 5), then hit the second-to-last checkpoint. They will see a Chao Box behind it, but they should not break it yet. Once Sonic makes it to the door with the last checkpoint inside (the checkpoint that is behind a switch), the player should hit the switch to open the door but not go through it. Once on the purple platform, head to where a G.U.N Beetle is seen. They should Spin Dash towards the wall, then perform a Bound Jump to be able to land on the highest platform. Next, they must Spin Dash and land on the gray platform (the platform with the goal ring), and once at the edge, jump to kill Sonic before going back on the platform. When the screen fades, kill Sonic again. If done correctly, after he respawns, the mission will be completed.

Players should be careful to not make Sonic touch the wall of energy guarding the Goal Ring from behind after entering the kill plane โ€” since it counts as an insta-kill, they can lose two lives instead of one due to an additional screen fade upon respawning at the Star Post.

During the status screen, the player must break the Chao Box that was by the last checkpoint, but not collect the Chao Key. Sonic should end up with an E Rank after his status is shown. The player must wait until he says "Barely made it" before performing a Spin Dash into the Chao Key. The screen should turn white and Sonic should end up in the Test Level (which is normally only accessed via cheating devices) with colorful shapes and numbers, followed by transparent items to pick up, put down, and throw. There will be no music playing. He is able to roam around, and if he jumps off of the stage, he will eventually hit an invisible floor at the immediate bottom of the area.

Depending on 2P Battle records, it seems to be possible to instead end up in stages Sonic is not supposed to be in, or at the Finalhazard fight rather than the test room.

Test Stage (Knuckles)[]

In Wild Canyon, find the Chao Key crate and then break it. Then climb the surrounding wall and go on the large X shaped platform above. Then press both of the camera buttons. After that step of the platform and the player should land on the Chao Key bellow. The Chao Key's HUD texture glitches so it shows the actual model of the key instead of the image. Now when Knuckles beats the stage he should get transported to the Test Stage.

Test Stage (Tails)[]

In Mission Street, Break open the Chao crate near the police cars. The player should make their way to the part of the level where the platforms tries to crush the them. When the camera locks, jump down and try to hover to where the Chao Key was. Due to the camera being too far away, the texture will not load so the icon is never generated on screen. Thus, Tails ends up being teleported to the Test Stage.

Chao is stuck on a wall[]

In the Hero Garden, the fallen pillars' collision do not seem to work right: when a Chao walks up to one, it gets stuck there until the player picks it up and places it outside of the pillar, or when the Chao does an action that does not involve walking: finding food on its own while hungry, running away in fear if abused, seeking attention from a character they like, etc. The Chao may also get stuck walking into the pillar for a few seconds, if it is hungry and found fruit on the other side of it.

This can also happen in the Dark Garden with the graves and fences, too.

Pyramid Cave jump-on-rail crash[]

In Pyramid Cave, should Sonic jump at the right time when "Great!" appears on the first rail, the game will crash. The reason this happens is likely due to the player having access to movement, rather than from their inputs.

Super Bounce[]

The "Super Bounce" is an exploit of the bounce attack. It is performed by Spin Dashing into a wall and on the approach towards the wall press the jump button and then the action button immediately after. Sonic's acceleration from the Spin Dash is maintained during vertical movement. The faster the player hit the wall from the Spin Dash, the higher the player will bounce. The result is Sonic flinging himself very high up to sometimes cause him to go out of bounds.

Mission 6[]

Note: This bug only exists in the Dreamcast version of the game.

In the level select screen, move to Chao World. Select it with A, but then press DreamcastB to go back rather than proceeding into the world. This is relevant because it causes the most recent menu to be a character-select menu with six options, instead of a mission-select menu with five. Next, go to any stage where all five missions have been completed. Hold A + DreamcastB at the same time to select it, and instead of seeing the mission-select menu, the screen will turn black. Navigate to the right five times, and then select the sixth option: the so-called "Mission 6".

The sixth mission plays identical to the first mission, but with some oddities:

  • On the title card, the mission description box says "Mission:", not "6th Mission" or even "1st Mission".
  • The mission objective is also unusual. Each level has an internal number unrelated to its order in the story, but rather based on the order they were created during development. (i.e., the objective of White Jungle will use Pumpkin Hill's description instead).
  • In most stages, completing this mission will softlock the game without writing any save data, rather than proceeding to the level completion screen. The only levels that will go through with a completion are Route 101 and Route 280.
    • Completing Route 101 will make the game write it as garbage to the chunk of memory reserved for Route 280 stats. Should one complete Route 280, the save data will be written as garbage to the memory where the Kart Race minigame data normally goes, but due to it being out of place, attempting to play it again on the save file will crash the game.

G.U.N. Truck Glitch[]

When the GUN Military Truck is in the air, perform a Homing Attack once. Then when it hits the ground, continuously Homing Attack the truck without moving the analog stick. When the player reaches the top of the hill, they will not be able to jump but they will be able to freely move around. Be sure to keep to the far left or right to avoid the triggering the Dash Panels. If the player keeps moving against the truck, they need to make sure that they do not touch it. It should end up clipping through the wall and get stuck in there.

Air Running Glitch[]

When the player is on the first stairs segment, Spin Dash up into the bridge and Sonic will start running up the side of the wall. Eventually he will start to run on thin air for a couple of seconds.

Idle Moonwalk Glitch[]

In City Escape, grab the tire next to the Dash Panel and place it in front of the Dash Panel. Then when the player picks it up Sonic will slightly move forward which ends up triggering the Dash Panel. They should then quickly throw away the tire. Sonic will just idly stand while being dashed back and fourth by the Dash Panels.

Hero Garden Building Glitch[]

In the Hero Garden. Jump on the top of the roof of the structure near the fountain and walk around on it. The character the player is using should get stuck running around in a circle.

Driving Backwards[]

During Route 101 or Route 280, it is possible to drift into a wall and make Tails or Rouge drive backwards. If the player stops drifting or goes too slow, they will return to normal.

Wild Canyon Clipping[]

In Wild Canyon, jump on the chest in front of the sandstone wall with the small pillar next to it. Then continuously run into the corner until Knuckles goes into his falling animation, then move the analog stick and jump. Knuckles should get forced through the wall and go out of bounds.

Magic Gloves Early[]

In City Escape, Spin Dash of the start of the loop. This should cause Sonic to easily be able to clip through many parts of land. While falling clip through the roof where the hidden 1-Up usually is. Then jump down again to where The Magic Gloves are meant to be. When the player sees the green room, immediately Homing Attack. The player will end up hitting a G.U.N. Beetle and then they can obtain the Magic Gloves much earlier.

Idle animation during results[]

This can only be performed in the Dreamcast version; the player must play as Sonic or Shadow, then pick a stage where the Goal Ring is next to a wall, either City Escape, Radical Highway, or Crazy Gadget. When the player reaches the Goal Ring, they must perform a Spin Dash, then jump towards the wall as they hit the Goal Ring. If done correctly, Sonic/Shadow will perform their wall-bumping animation, and as the game transitions to the results screen, they are seen getting up off the ground and standing completely still as opposed to doing their victory animations. If the player waits long enough, Sonic/Shadow will begin their idle animations and dialogue that get cut off as the game loads out of the stage.

This bug would be addressed in subsequent releases, where attempting to perform it will still make Sonic and Shadow do their victory animations like normal.
