Parasite is a colossal doomsday machine hyperstructure that has been implanted onto the crust of the Earth's surface by the Mykonians to harvest heat directly from the Earth's core.
Parasite is a set of special unique sectors found in Set 6, which contains one primary component sector (the 'core elevator') at the centre, and four large supporting energy pillars that are positioned diagonally around the middle sector. In the single-player campaigns, the Parasite serves a similar function as the Stoudson Bomb (in fact, it is actually a type of the Stoudson Bomb in the gameplay context) in that it is a large-scale weapon of mass destruction with a set timer and trigger sectors required for its operation, whose detonation will propagate an energy shockwave towards all directions that can eliminate the entire structures and hostile units present in the level once the timer reaches zero.
The Parasite serves as the primary strategic target of the original Resistance campaign, and it is the player's ultimate objective to effectively stop and disable the Parasite before it reaches its final phase in the final level, Parasite City.
Parasite is a gigantic doomsday machine and a large-scale energy harvester and converter that has been installed on the surface of the Earth by the invading alien group Mykonians. During the early phases of the Mykonian invasions upon the Earth, the Mykonians have quickly gained supremacy with their advanced weaponry and technological superiority, and most importantly, exploiting the unstable geopolitical and diplomatic situations amongst the fractured human factions on the Earth following the events of the Big Mistake. The divided human factions and alliances allowed the Mykonians to swiftly gain upper hand and install their Parasite machine unimpeded with minimal interference.
This 'core elevator' can harvest thermal energy directly from the Earth's core at an alarming rate, while also releases any excess heat gathered from it to the Earth's upper atmosphere. This entire process results in extreme cooling of the Earth's temperature while also weakening the planetary magnetic field, which adversely affects the Earth's magnetosphere, thermosphere, and ionosphere. The process also renders the already devastated and uninhabitable surface of the Earth after the Big Mistake more susceptible to the bombardment by unfiltered cosmic radiation at its extremity, while plummeting the Earth's temperature to the lowest for a total extinction of all lifeform and biosphere on the Earth.
The Parasite contains one main component sector situated at the centre, with four supporting energy pillars positioned diagonally from the middle. Aside from the aesthetics and visuals, it serves a functionally identical purpose as the Stoudson Bomb in the most gameplay context. The central 'core elevator' sector is the main component of the bomb itself, while the rest of the supporting pillars are the trigger points. All five sectors are virtually indestructible, although they can still be damaged and also captured.
The Parasite is an extremely unique sector and makes its appearance in the game only a few times.
4.1 Resistance Campaign
Parasite City: The Parasite makes its appearance in its namesake mission, and it is the final end goal objective of the original Resistance single-player campaign. By the time SDU7 arrives in Parasite City, the countdown timer of Parasite is still ticking with 45 minutes left before it reaches its final phase. Otherwise it works functionally identical to Stoudson Bomb in the gameplay.
4.2 Ghorkov Campaign
During the course of the Ghorkov campaign in Metropolis Dawn, the Mykonians manage to re-construct not just one, but two Parasite machines this time as their final effort.
Parasite Under Construction: The player (Conrade) receives a report that the Mykonians are busy constructing a new Parasite somewhere in Siberia, where the Mykonian presence is still dominant. The Parasite is located on top of the Mykonian hill that is situated at the south-western part of the level. Initially the Parasite is not functional, but the Mykonians will activate it at some point during the battle. This Parasite has a timer of 15 minutes.
Parasite Dome: The Parasite Dome is the final level of the Ghorkov campaign. The Mykonians are once again constructing their third and final Parasite on a large, artificial volcanic island off the coast of Japanese Archipelago. The Parasite is located at the central part of the level, and it is protected by substantial Mykonian forces and defence lines. This Parasite has a timer of 45 minutes. It is implied in the mission briefing text that the victory over the Mykonians here will terminate their invasion, potentially marking the beginning of the end of Mykonian interference on the planet Earth.
4.3 Multiplayer Levels
- The Parasite earned its name from how it extracts the energy by leeching heat from a planet's core, in which case the Earth would be the Host.
