Reactor Sabotage is a Sabotage variant that was introduced in Update 18.5 (2016-03-04) to replace the sabotage that takes place on the Grineer Galleon and Corpus Ship tilesets. In this mode, the player must sabotage the two coolant stations of the reactor before destroying the reactor itself using either the fuel cell or the coolant cells collected. During these missions, players can also find Resource Caches that contain rare goods, but are hidden out of sight.

Note that "Reactor Sabotage" refers only to the missions on the Grineer Galleon and Corpus Ship tilesets. While there are a number of Sabotage missions on other tilesets also involving reactors, they do not involve the fuel/coolant cell interaction, and most notably they do not have Resource Caches to collect.


There is at least one coolant room located within the ship: two coolant rooms for Grineer Galleons and Invasion mission Corpus Ships and one coolant room for other Corpus Ships. Each coolant room contains a coolant station within which a coolant cell is installed. Players must navigate to the coolant cell and extract it, but the rooms are defended by laser barriers and security cameras; getting caught by them will lock the coolant cell in place, forcing the players to destroy it instead.

After extracting or destroying all coolant cells, Objective affinity will be awarded and the reactor core will eject its fuel cell as a failsafe. The reactor can then be sabotaged in one of three different ways, before the reactor must be hacked to reactivate it. Each method will cause a different environmental hazard after the reactor destroys itself.


If the fuel cell is reinserted into the reactor core, the player must then destroy the emergency fuel injectors that become exposed on the reactor.

On a Grineer Galleon, the ship will immediately start overheating, creating various sources of DmgHeatSmall64.png Heat damage throughout the ship, capable of burning both the player and enemies alike. If this is not an Invasion mission, a blast door will be activated between the player's location and extraction, requiring them to hack a console in order to open the blast door and escape; Objective affinity will be awarded upon a successful hack of this console. The fire hazard will steadily spread throughout the ship after the reactor is sabotaged, and after a few minutes, the Lotus will warn players that the reactor is close to critical, at which point a timer will be displayed counting down to its final detonation, and mission failure if the players do not extract.

On the Corpus Ship, the reactor will begin to go critical, and a five-minute timer will begin to elapse immediately after destroying the fuel injectors. There will be lowered gravity and numerous magnetic fields which, when approached, will pull players towards them and apply a DmgMagneticSmall64.png Magnetic proc on contact. These bubbles can be temporarily disrupted for 12 seconds by DmgElectricitySmall64.png Electricity, DmgVoidSmall64.png Void, or DmgMagneticSmall64.png Magnetic damage, making them explode and deal DmgElectricitySmall64.png Electricity damage to all nearby units. Instead of a blast door, an immediate lockdown will occur. Lifting this lockdown, while necessary for extraction, will not award Objective affinity.

If all coolant cells end up locked down and destroyed, this is the only method players can take.


If a coolant cell is inserted into the reactor core, the players will have to defend four coolant pipes within the reactor room from approaching enemies for 75 or 120 seconds for, respectively, Corpus Ships or Grineer Galleons. The mission will end in failure if all four pipes are destroyed during this mission phase.

Once the defense timer has elapsed, as indicated by decay reaching 100%, Objective affinity will be granted and the ship will experience numerous coolant leaks, manifesting as patches of ice that appear all over the ship. If touched, this ice will apply DmgColdSmall64.png Cold procs that drastically slow the player or any of the enemies. However, this coolant leak will not reduce shields, unlike the environmental hazard.


If the fuel cell is inserted into a coolant station, the player will have to defend the reactor's control console for 60 seconds from Eximus enemies attempting to access it while the reactor erodes. Lockdown, which is usually caused by an Eximus enemy reaching the console and remaining there for 1.5 seconds, will pause reactor decay until it is lifted. Objective affinity will be granted once reactor decay has progressed to completion.

On a Grineer Galleon, the ship will experience a blackout, lowered gravity and numerous magnetic fields as with the Corpus Ship Meltdown above.

On a Corpus Ship, a complete blackout will occur, reducing visibility and enemy accuracy.

The fuel cell can only be placed in a coolant receptacle that has had its cell removed; if the coolant cell was destroyed, the fuel cell cannot be placed in it.

Resource Caches[]

The three Resource Caches that can be found in this mission type can reward resources, credits and Endo with the amount depending on mission tier and the number of caches found. If all caches are discovered, it is possible for one of the rewards in the final cache to be a Xiphos part or Nitain Extract. With thorough exploration, it is usually possible to find all three caches before starting the sabotage sequence.

Affinity rewards scale with mission level and are given for extracting a core (but not for destroying it) and upon completing the objective of each phase of the sabotage. Finding a resource cache additionally rewards half the mission's objective affinity.

  • Arrows will be pulled towards the magnetic anomalies.
  • If a fuel cell is placed in a coolant cell receptacle, this can be overridden by placing a coolant cell in the fuel receptacle, or vice versa. The mission will continue according to whichever happened most recently.
  • It is possible to destroy the reactor´s fuel injectors with remote detonation weapons such as the TaserStar.png Castanas, U18throwingknives.png Talons or DEPenta.png Penta, provided that a player witnesses the explosion. Should there be no player present during the explosion, the explosion will not affect the fuel injectors and the player will have to backtrack and destroy the injectors.
    • This also works with Limbo's Cataclysm, which can destroy all the injectors at once with its collapse blast.
  • Invasion variants of Reactor Sabotage retain the coolant rooms and fuel cell/coolant cell interactions, but do not contain Resource Caches.
  • The reactor room of a Reactor Sabotage will usually hold several Eximus enemies when first entered. These spawns, when combined with the guaranteed Eximus spawns during a Magnetizing console defense, make Reactor Sabotage a good non-endless option for farming Eximus kills for Nightwave Acts.


  • If the fuel cell is placed in a coolant cell receptacle and the console is hacked, it is possible to put the coolant cell in the fuel receptacle and hack the console again to trigger both cooling and magnetizing environment hazards.
  • On Grineer Galleons, it is possible to pass blast door before it closes due to the timer. In that case, you have to backtrack to trigger it again, since you would not be able to evacuate without doing so.
  • Sometimes during a Corpus Ship sabotage, players could not place the coolant cell in the console making the mission incompletable and forcing players to restart the mission. This has only been tested out on Ishtar, Venus.
  • During a Magnetizing console defense on a Corpus Ship, Eximus enemies will spawn but will not run toward the reactor's control console.
  • Tripping coolant room laser barriers or cameras does not lock the coolant cell in place on Corpus Ships.
