The ShockPoint Drive is a means of interstellar travel invented by astrophysicist Hideki Ishimura.
Although little or no information on its method of operation is provided, the initial loading screen for Dead Space provides some clues as to its mechanism of operation. The depiction of space-time (via a two-dimensional model) relative to the rear of the ship expanding while that in front of the ship is contracting seems to indicate the concept is related to/derives from the theoretical Alcubierre drive, a proposed means of achieving faster-than-light travel.
Further supporting this is the visual distortion enveloping the ship as observed in the opening sequence of Dead Space, as if the ship were in some "field" or "bubble" (the Alcubierre drive concept calls for the entity being transported to be enveloped in a sort of "warp bubble", a region of static space-time which does not undergo distortion).
Prior to the conception of the USG Ishimura, the ShockPoint Drive had only been used on smaller personal vessels. This implies some type of complication regarding the size of the ship. Exactly what this is, as well as all other information regarding the ShockPoint Drive, is unknown.
In the Awakened DLC for Dead Space 3, Isaac Clarke and Sgt. John Carver retrieve a ShockPoint Drive from a gutted shuttle on the CMS Terra Nova above Tau Volantis. They retrieve the ShockPoint Drive and place it in the ancient reactor. However, in order to utilize the drive on the Terra Nova, Isaac and Carver overload the reactor by dumping plutonium cores into the reactor which generates enough power to shock out back to Earth.
The following below are terms and functions used in conjunction with ShockPoint travel. All spelling and formatting have been provided by text from Dead Space: Liberation, Dead Space: Salvage, Dead Space 2 and Dead Space 3.
- Shockspace – The “void” between two points. Ships or shuttles are unable to be travel through it without a beacon or coordinates to an exact location.
- Shock out – The action of entering Shockspace.
- De-shock (Shock in) – The action of dropping out of Shockspace when a ship or shuttle has reached it destination.
- Shockbeacon – a device used to lock on to the location of a ship that travels through shock space
- ShockRing – a devices that aids in the effort to travel across the void between two points.
- ShockPoint facility – a station or establishment that caters to ShockPoint travel, providing beacons and triangulation for locations.
- Shock-Gate – transmission codes that activate ShockRings.
- ShockSpace looks similar to Hyperspace from the Doctor Who series.
- The ShockPoint Drive appears to be at least 200 years old, since it existed during the Aspera incident in Dead Space: Catalyst, only that the ShockPoint Drive usually took weeks to reach far distances.
- It is mentioned in Dead Space: Aftermath that the Shockpoint Drive is one of humanity's greatest inventions.
- Hideki Ishimura is mentioned in the novel Dead Space: Martyr, during the outbreak in the laboratories.
- For smaller vessels, such as the USG Kellion, there is a big quad-cylindric construction that appears to have the drive for interstellar travel. This way, a light vessel can be light and maneuverable for atmospheric issues, leaving the module on orbit, or fly across the galaxy using it. However, bigger vessels, as USG Ishimura and or the USM Valor have built-in drives.
- The ShockPoint Drive has been repurposed as a bomb and also a multiplayer objective in Dead Space 2. This may be similar to the events of Dead Space: Salvage.
