Activated Soul Cube

The Soul Cube is an ancient Martian artifact and the most powerful weapon in Doom 3. In the default keyboard settings, press the "Q" key to bring up the Soul Cube. Its name may be derived from the soul sphere item in classic Doom.

SPOILER WARNING: Plot details follow.

HistoryEdit

After the Martian race first encountered the forces of Hell at some point in their past, they ended up in a hopeless struggle against its demons. With whatever conventional weapons they had proving ineffective at stemming the horde, they eventually devised a plan using their greatest technology, which bordered on functional magic. Most of the survivors were sacrificed, and their souls were used to create the weapon that would turn the tide: the Soul Cube. With it, their single greatest champion, simply called "the Hero", (a take on the Doomguy's namelessness) took on the invading force singlehandedly and managed to seal the portal. "The Hero" didn't seem to survive since his burial chamber was found. He appears to be very tall, because his tomb is very long. The Cube was then buried along with other artifacts near the Hero's burial chamber, in case anyone ever had to deal with the forces of Hell again.

Ages later, human archeologists on Mars discovered the Soul Cube, and through the translation of the Martian tablets, learned of its purpose. Director Larry Bullman was the one who first theorized that the Soul Cube was a weapon.

During the gameEdit

Soon before the Mars invasion began, Dr. Betruger took the Soul Cube and went through the teleporter without authorization to have it contained in Hell. Now in possession of the only weapon that could defeat them, the demons invaded the UAC Mars Base.

The Marine receives the Soul Cube at the end of his trek in Hell, just after defeating the Guardian boss. After the Player obtains the Soul Cube, it gives a speech, with the most important words informing the user that they (the souls of the Cube) are "the Praeleanthor" (possibly the name of the Ancient Martian race) and that they are the only way to defeat "Hell's Mightiest Warrior" (the Cyberdemon).

"We are many, we are one, we are the Praeleanthor. You know us as the Soul Cube. Free us from our eternal prison and we will help you. Vanquish our enemies and we grow stronger. Listen for our call and then free us, to smite down the evil."

With the Cube's aid, the player fights his way through the demonic forces to the Hell Hole, where he confronts the Cyberdemon that guards the portal. After a great battle with the Cyberdemon and its minions, the marine and the Soul Cube triumph. The Soul Cube slices off one of the Cyberdemon's legs, then impales its blades into the demon's skull, killing it. After killing the Cyberdemon, it proceeds to travel into the dimensional portal and seal it off, causing lava to boil up to the top and solidify. The Cube's ultimate fate is not clear. It was either destroyed (sacrificing itself) or trapped within the portal in order to destroy Hell's only link to human dimension.

OperationEdit

The Soul Cube is powered with the life force liberated following any death, including humans and allies, at the hands of its current user. Five kills will leave the Cube ready and fully-charged, and it will then say, "Use us." An indication will be when the Cube is lit up at its five orbs (four on the side and one in the center). The Cube then displays a large intersecting collection of whirling circular blades, before zooming off to the target, passing through obstacles and damaging it with the said blade array. During its attack, the player's normal weapons replace its position at the helm. It also transfers the target's life force to the user, partially or completely healing any injuries the player may have, depending on the remaining hit points of the main target when the Cube strikes. The Soul Cube attacks intelligently; it always attacks the enemy with the largest amount of hit points within range, and homes in on the target. This targeting can be overridden by aiming the screen reticle at a particular target. The damage per Soul Cube attack is 1,000, and splash damage of 40 to adjacent enemies. The maximum health that the Cube can restore to the player is 99. The rate of restoration is 5 health points per interval, and two intervals per second. The Soul Cube will not restore damage taken after the attack begins, but before it is completed. Be aware that it is possible to launch the Soul Cube without a valid target, in which case the charge will be wasted at no effect.

Only the boss demons, like Sabaoth and Cyberdemon, can hope to survive even a single Soul Cube attack (4 attacks to be exact to kill the Cyberdemon), and even then the Cube still performs a life force transfusion. The Cube then retracts the array and returns to the user until its wielder inflicts enough deaths to re-energize it.

It should be noted that the life force absorption seems to be only needed to power the Soul Cube's movement and homing functions. When it is idle, it occasionally displays its blades and spins for a brief period of time.

The Soul Cube does not attack monsters that are unaware of the user's presence.

PropertiesEdit

  • It is immune to radiological scans of any nature, including X-rays and gamma rays.
    • Its atomic makeup cannot be analyzed for this reason.
  • It maintains a constant temperature of 98.8 degrees Fahrenheit (37.1 degrees Celsius), regardless of surroundings (as the natural, constant body temperature of a human being is 98.6 degrees Fahrenheit, then 98.8 degrees Fahrenheit is likely the natural, constant body temperature of a Martian being, since the cube is composed of Martian souls).
  • It levitates. (At least it does after the player acquires it; one scientist described it as "an elaborate paperweight")
    • This would make it rather difficult to measure the Cube's mass. Theoretically, the Cube could be launched at a constant speed to measure impact force, from which its mass could be inferred. Since "all attempts to determine its mass have met with no success", it was probably tried, among various other methods.
  • It is apparently immune to damage, at least from conventional sources.
  • It is not a perfect cube. Portions of it are ornamentally decorated, and one entire corner of the Cube has been cut into with ornamental sculpting that seems almost organic, resembling a face with four eyes.
  • It is sentient, thanks to the souls used to create it.
  • It possesses very high armor penetration, being the only weapon capable of damaging the otherwise invulnerable Cyberdemon.
  • Despite very sophisticated attempts to open and scan through the Soul Cube, nothing was discovered about the Soul Cube's operating mechanisms or interior until the player found it.
  • It does not actually use the souls of its user's slain victims to power itself. Rather, as Larry Bullman explains in his report, the Cube "senses" deaths at the hands of its user and somehow extracts energy from these events.
    • The Cube does not store "extra" energy from kills beyond the required five (in other words, killing ten enemies does not allow you to use it twice in a row).
  • The Cube does not have a physical firing mechanism, but it follows the wishes of its owner precisely. This may indicate that it shares some kind of psychic connection with its user.

Strategy Edit

The Soul Cube should be reserved for larger enemies, like the Hell Knight or Arch-Vile, and bosses like the Vagary and Sabaoth (be sure to have it fully charged.) Since the Soul Cube requires five kills before it becomes operational, it is advisable to use it primarily on stronger enemies depending on the type of monster you are having trouble with. This does not mean that the player should completely reserve using it when swarmed by small enemies like Trites or Cherubs. This is because the splash damage from the cube's attack is likely to dispatch several targets at once, and the availability of many tiny targets ensures that the soul battery is very easy to refill throughout the encounter.

As stated above, when charging the Soul Cube the best enemies to kill are ones with few Hit Points, such as the Trite, Tick, and Lost Souls & it is possible to fuel up the Soul Cube by killing Humans.

TriviaEdit

The concept of feeding a weapon with the "souls" of killed enemies might be inspired by the Doom Bible. At the ammo section, it was told that the demon-styled weapons (like the former Unmaker) used the "Killed humans" ammo.

The Soul Cube's history in the context of the game resembles that of the ancient Greek Antikythera Mechanism in real life (it was discovered in 1901 but eluded understanding until 2005, when, with the help of a jet engine X-ray machine resembling the Scan Matrix used on the Soul Cube, scholars finally began to understand how it actually worked.) Text on the ancient stone tablets associated with the Soul Cube in the game bears some resemblance to text found on the Antikythera Mechanism with the help of advanced imaging technology. A video by Scott Pagano featuring the song by BT (Brian Transeau) named after the Antikythera Mechanism shows a cube apparently creating a city. Otherwise, the Soul Cube, Antikythera Mechanism, and music video appear to be unrelated, even by inspiration, making these resemblances a remarkable coincidence.
