On The Skeld, the Reactor is a room located in the corridor across from Security. It contains two vents that connect to only one location (the upper one is connected to the Upper Engine, while the lower one is connected to the Lower Engine). While the reactor normally glows blue, it will begin to glow red if sabotaged, with paths to the hand scanners lighting up.
In MIRA HQ, the Reactor is connected to the Laboratory, which contains a huge reactor with a claw that emits a laser (which can change color if the reactor is sabotaged), several computers, and two hand palms that are used to repair the sabotage of the reactor, just like on The Skeld. But, to get to the Reactor, Crewmates must first go through Decontamination. A vent is located on the left below.
Although there is no room with the name of Reactor, there are two reactors located Polus, called "Seismic Stabilizers", which are located on different sides (one on the left and one on the right). They consist of huge towers with a module at the top, which seems to emit a signal, and in each is a palm that serves to repair the reactor's sabotage. They are connected with the holes that are near them.
Impostors can sabotage the Reactor, which gives Crewmates 30–45 seconds to resolve the sabotage (30 seconds on The Skeld, 45 seconds on MIRA HQ). The way it is resolved is by two players scanning their hand at different stations simultaneously. If it is not resolved in the allotted time, the Impostor(s) will win.
