The Space Colony ARK. 50 years ago. That's right. This will remind you what the humans did to you. Never forget that horrifying image!

Black Doom, Shadow the Hedgehog

The Doom is one of the fourth Stages in Shadow the Hedgehog. It is reached by completing either the Normal mission of Cryptic Castle or the Dark mission of Prison Island.



Shadow wanders through the forest after his last mission, back to introspecting about his identity just as he did at the very beginning of the game. Once again, Black Doom manifests in front of the hedgehog, though this time with a more powerful illusion - the entire world melts away as Doom apparently delves into Shadow's memory, to produce a simulacrum of the events on the Space Colony ARK 50 years ago. Watching from afar as his past self flees through the corridors with Maria Robotnik with the squad of GUN soldiers hot on their tail, Shadow listens as Black Doom further instills thoughts of hatred against humanity into the black hedgehog's confused mind.

This entire level therefore seems to take the form of a flashback; Shadow remembering what he did during the GUN assault that shut down Project Shadow. Not free of moral choices even half a century ago, Shadow can defend the ARK by killing the GUN troops directly in the Dark route, spurred on by Doom's Eye (though whether Doom was physically there on the ARK 50 years ago, or is simply inserting himself into the memory to mess with Shadow's head, isn't clear), or do as Maria says and heal the injured ARK researchers by bringing healing units to them, or take the Normal route and simply escape with Maria as fast as possible.

Whichever course Shadow chooses, his and Maria's escape after the level is blocked by the GUN Heavy Dog boss.



The following weapons can be found in The Doom:

Secret Key locations

  1. Exit the starting room and activate the elevator. Get in and go to the upper level. When the elevator descends, get on top of it and jump to the Key when it rises again.
  2. Upon entering a long sloped hallway, Spin Dash up the incline and then jump to reach the Key located on the catwalk.
  3. Once at the first Bomb Server, destroy the cracked wall to the right to reveal the Key.
  4. Enter the fan room after the second Save Point and use the pulley to get to the upper level. Use the wind from the fan to reach the Key.
  5. Continue up the elevators after the third Save Point and use the green containers in the right corner as a stepladder to reach the rafter above. Destroy the containers and the Key will be behind them.

Behind the Secret Door is a switch that will open a case containing a single Ring. Upon collecting said Ring, the platform next to it will begin moving when Shadow stands on it. This allows access to a big shortcut that is very helpful with the Normal Mission.


Story Mode

Dark mission

Guide Mission Objective
Shadow the Hedgehog - Dark Mission - Doom's Eye.png Annihilate the GUN forces! Defeat 60 GUN soldiers.

At each Save Point, the player should have defeated the following amounts of GUN soldiers:

  • Save Point #3: 35
  • Save Point #4: 45

Grab some weapons in the first room, and in the following room, Slide under the door to reach the first checkpoint. In the next room, defeat the four GUN soldiers, and go through the door to find the Doom's Eye. In the next room, Soldiers will break through the walls on either side.

Normal mission

In the room with the second checkpoint, the player will want to activate the lift, and get the Grenade Launcher out of the GUN Container. This weapon is capable of destroying the cracked walls. The player should use the Grenade Launcher on the cracked wall below, destroy the GUN Trooper, and with its weapon, continue until they reach the long room with the two more GUN Troopers and fourth checkpoint. After, they need to go straight through the door. When the player reaches the fan room with the three GUN Troopers, they need to go right and down the slope. At the bottom of the slope, they should go through the cracked wall to the right, bounce off the three Gun Beetles to cross the gap, and go through the door to enter another fan room.

Hero mission

Guide Mission Objective
Shadow the Hedgehog - Hero Mission - Maria.png Save the captured researchers! Use Heal Units on the ten injured researchers.

The Heal Units are usually close to the researchers they are intended for. Also, if unlocked, the Heal Cannon works just as well, if not better. If a Heal Unit is used on a GUN troop, they will stop attacking. It will also help Shadow fill the Hero gauge.

The ten Heal Units and researcher are in the following locations:

  • The first Heal Unit and researcher are in the first room.
  • From the first researcher and Heal Unit, continue into the next room, and slide under the wall to get to the next area with the first checkpoint. When the player goes through the door, The player will ends up in a larger room. This room has a Heal Unit and two researchers
  • Exit the large room with the two researchers, and go through the other door. The player will arrives in a new area. Go left and some GUN Soldiers will bust through the walls on either side. Go through the door instead. At the end of the path, the player will find a Bomb Server. Use the bombs to destroy the cracked wall on the left, and go through the door to reach another long room with a Heal unit. The injured researcher is behind a cracked wall just left of the Heal Unit.
  • Go straight through the door past the second checkpoint, and the player will find a researcher. The Heal Unit is located to the left guarded by two GUN Soldiers.
  • After entering the open room with green rail, activate the elevator by touching the switch and go up. This path will eventually lead to a dead end, but the player will find a Heal Unit and two injured researchers.
  • Return to the bottom of the room where the player hits the switch for the elevator , and go through the door on the right. Slide under the opening, and in the next room is an injured researcher. The Heal Unit is on the other side of the moving platform.
  • After rescuing the eighth researcher, go back to the side with the Heal Unit and the Bomb Server. Use a bomb to destroy the cracked wall. This will lead to a series of fan areas. When the player gets through these areas, go through the door on the right. The player will arrive in a long room with two GUN Troopers. Destroy the Two GUN Soldiers that burst out of the wall, and heal the researcher within. To get to the final researcher, the player must triangle jump across the gap further ahead.

Expert Mode

In The Doom's Expert Mode, the player has to rescue all the wounded researches. Despite this, all ten researchers are located in the room where the Goal Ring was in story mode, with there now being a Heal Unit right outside the door. Due to this, the Stage is not much different than the Normal mission in story mode, aside from a few harder enemies.


Main article: Heavy Dog

Shadow and Maria facing the Heavy Dog, from Shadow the Hedgehog.

The boss of The Doom is the Heavy Dog, a G.U.N. battle vehicle. The guide for this battle is Doom's Eye.

Shadow's Homing Attack is required for the first part of the battle in order to destroy Heavy Dog's guns. After the first gun is destroyed, it becomes a usable 4-Shot RPG. This weapon allows multiple lock-on targets at once, with more ammunition coming from destroying more of Heavy Dog's weapons.


  • In the cutscene before the level itself, the scenery is actually different depending on which level the player went through before: Prison Island makes the forest all green while Cryptic Castle makes it red.
  • While playing the Hero mission and running down a slope, Maria comments that Shadow used to race down the slope often. This is the only known mention of what Shadow may have been doing on the ARK when not with Maria.
