Expert Mode is an unlockable gameplay mode in Shadow the Hedgehog where the player has to play through all of the game's stages in order to complete it. Expert Mode can only be unlocked in the game by attaining an A-rank on every single stage in the game.
Plot-wise, it is a form of training that Shadow apparently goes through shortly after the events of the game and is to be a true test of Shadow's skills.
In Expert Mode, the player plays through all 23 stages (including The Last Way) available in Shadow the Hedgehog in order, starting from the top of the level select chart down. Unlike the main game, progress will be lost if the player loses all lives. Many of the first stages are nearly the same, just a few extra platforms and some more rings to use Light Speed Dash. No characters are allied alongside the player and there is no given Rank after completing a stage. The objective of most stages is to reach the goal ring except for Central City (clear annihilator bombs), The Doom (rescue wounded researchers) and Mad Matrix (reach all four data-bases). The beginning of every stage has a Hint Ring marker containing a message from a different character wishing Shadow good luck and telling the player how Expert Mode works.
During the first drop, avoid the helicopters on the way down, When the bottom is reached, continue forward by defeating all the Black Arms in the way. By the time the player reaches the area with a lot of red roots, the player will have a full Hero Gauge. Be careful, because there are more GUN Soldiers and Black Arms. Laser blasts are also more frequent, So watch out as well. If the player did not have a full Hero Gauge by the area mentioned above, the player will need to Triangle jump along the way and then Light Dash at the rings.
The first thing that the player will notice is that there are more firewalls in the light Dash Circuit. Avoid them at all costs to keep from losing rings. When the player reaches the area after the first checkpoint and some GUN Beetles, hop on the moving blocks, Light Dash along the rings, and use the spring to get up to the light in the next section. There are also some differences in certain sections, but if the player takes it slow, they should be able to get to the end.
The stage is much easier than Digital Circuit, because the only thing that has been changed is the way to get across some gaps. There are a few more platforms and Light Dash opportunities. In the area where the wind automatically takes the player up, there is no wind, meaning that the player has to makes their jump manually.
The first noticeable difference is the lack of some rockets. After using the Pulley where the first rocket should be, there is a locked spring. So, the player must defeat the GUN Beetle flying in the air just beyond to use the Spring. The player should have a weapon, to shoot it, and then the Cage will open. Afterward, the player needs to jump out to the rings, and Light Dash the rest of the way. The player's hardest jump will be to that of a pulley over nothing. Try to jump toward it and then Jump Dash for extra distance.
The player may notice that the first balloon is gone. But by defeating the Egg Pawn, and a Skull Spring near its location, it will appear. Use that spring to bounce up to the top portion, and grind down the rail. After the fifth checkpoint, get on the moving platforms, bounce off of the Black Hawk and then use the Light Dash to make it across to the other side.
In the area where the original Goal Ring was, defeat the Black Arms and then bounce up. From there, use the Wide Spring to bounce high, and then use the Homing Attack on the Gun beetle and then Light Dash across the newly formed rings. Later on in the stage, the player will have to take a ride on an Air Saucer that will take them to a platform with robots. Once there, the player must time their jump and bounce off the two GUN Beetles to get to the other Air Saucer.
Besides the increase in enemies, there are more of those tiny moving platforms. It is important that the player is very careful when jumping to them. Take this stage slow, and remember It is not about time but completion. The most difficult part is after the rope grinding section. The player must jump over to the small moving platforms, and do some hoop tricks after that. The rings in mid-air serve as a guide to where to jump to, but it is better if they are just skipped using Chaos Control.
The object of Central City is not to find the Goal Ring, but to destroy the five giant bombs found throughout the city. The bombs are located in the same places as the Normal Story Mode.
In this stage, the player has to rescue all the wounded researches. For this stage, one will need to use all the shortcuts they used to reach the Goal Ring in story Mode, because all the researchers are in that room.
The player will have to use the Light Dash here a bit more than they used it on the Normal Story Mode. One thing to take note of is that after the long Light Dashing section, the player must hold forward in order to land safely on the solid ground.
One thing that is different in this version of the stage is the color tiles. There are more of them to line up. Besides making the level longer, it should still pose no problem.
Pass through the Dash Ring to bounce off a spring that leads to an incomplete platform. After that, the player should land on one of the tiles, and must change them to the same color to make it rise. When the player reaches the next set of tiles after the third Checkpoint, it also has incomplete tiles. When the player reaches the top, they will need to Jump Dash to the other side.
There are more Color Panels in this version of the stage than in its regular version which the player has to match up their colors in order to activate them. During the last Color Panels that escort the player to the main room, they should stand to the far left or right of the Color Panels in order to avoid being knocked off.
In the story mode after riding the platform up, the player had to triangle jump. But, in this version of the stage, there are two floating blocks. Jump to the first block, and jump Dash to make it to the second block.
The stage is altered a bit. The player can accelerate through the stage by shooting some enemies and filling their Hero Gauge, so that they can use Chaos Control to reach the area with the pole to slide down to reach the final part of the stage faster.
This is just like the normal Mission, except for the fact that the player cannot destroy defense cores to remove the barriers. Just stay on the Black Volt, and fly as fast as possible through the stage to reach the Goal Ring. Luckily, the player can refill the Black volt's health two time during the stage. If the player gets off Black Volt, they must restart the stage at the first chapter as no Black Volt reappears once the player gets off of a one.
This stage calls for making good use of the Chaos Control. And if the player can power their Hero Gauge up so that it is full just before the outside sections of the stage, they can use their Chaos Control to navigate through the rest of the stage.
The first thing that the one will notice is that there are a lot more platforms than before. This is Expert Mode, so the player is not going to be bailed out by rockets and such. If the player hits most of the checkpoints by the end of the stage, they will get extra lives.
The only changed element in this version of the stage is that at the point where the second defense unit was, there are blocks not barriers.
The most noticeable change is the lack of some Gun Lifts. When the player reaches the first part where a Gun Lift used to be, they should go through the door, and a platform with a rocket will be there. Use the rocket to reach another platform, and use the Dash panel to go forward. After using the Dash panel, the player needs to use a series of Homing Attacks to reach the other door. The Goal Ring is in the area with the Final Checkpoint.
The first part is standard, except it does not matter who the player defeats. Watch out before the first checkpoint, because there are a number of places to fall. Use the Jump Dash to increase distance and make it a goal to build up the Hero Gauge, so that the it is possible to skip some portions of the stage using Chaos Control. In the final area before the Goal Ring, be sure to defeat the GUN Before jumping across the platforms.
This stage has nothing more than an increase in enemies.
This is Expert Mode, so the player will need to have mastered the Triangle Jump, or they will not be able to pass even the first part of the stage. Try to stay on the top portion, because it is easier. The first couple of volcanic defense systems are active, but the Goal Ring is located where the fifth one was. Make sure not to take the other path, or it is over.
What makes this stage expert is the lack of enemies. Before, one could use the Black Hawks to get from platform to platform, but now the player must use the Jump Dash.
A trick to skip an entire section starts in the inside corridor after the second checkpoint. In the room with the Artificial Chaos, jump down to grab a Pulley, and when the the upper platform is reached, grab the blue energy core. Use it right away, and ride the transport outside. As soon as Shadow lets go, use Chaos Control again in order to skip an entire section.
After the Sixth Checkpoint there is no Jump Vehicle and instead, the player will need to use the pulley. Once at the top of the pulley, wait for the platform to float by, and jump on to it. This is not much harder, but there is more chance for error. The next Section is especially tough, because the player must jump on a series of moving platforms.
There is no time limit in this version of the stage.
The player should focus on filling up the Hero Gauge and use Chaos Control. There are no defense cores to activate, so the player will need to get through the stage using the pure hero path. The Goal Ring is where Black Doom is.
The Last Way
To finish the Expert Mode, defeat as many of the Black Arms as possible, and use Chaos Control to fly through this stage. At the end of this stage, the credits are displayed.
Every characters from the game including Cream the Rabbit, Cheese, Gerald Robotnik, the Commander, and even the President and his Secretary will start a conversation when touching the hint markers at the beginning of each stage.

- The Expert Mode version of The Doom is the same as the Hero mission, except that the researchers are all next to a Heal Unit spawn in one room at the end.
- Important and sometimes interesting information is often revealed by the hints at the start of each level in Expert Mode. Aside from the objective of each level, personal information from the speaker is sometimes revealed such as the Commander's new grandchild, the reason for the hostile actions of the Artificial Chaos, and the President's meetings.
- In Mad Matrix, Omega claims that he is stronger than Shadow and challenges him. He wants to challenge Shadow again in Lava Shelter, but Rouge stops him.
- In Iron Jungle, Dr. Eggman asks if Shadow is angry with him, which may refer to Shadow Androids.
- The President tries to talk with Shadow in Air Fleet and Black Comet but in both cases his Secretary reminds him of his meetings and he has to stop talking with Shadow.
- At the beginning of Final Haunt, Charmy and Vector fight with each other about minor matters and Espio apologizes to Shadow about it.
- Gerald Robotnik says in Lost Impact that the reason the Artificial Chaos became hostile was because Gerald accidentally reversed the positive and negative electrode connectors within them. This created a problem in their programming and resulted in their hostility.
