Nuclear Power Plant Complex Guide: The three roles and what they want
About
OverviewNuclear Power Plant Complex drops you into a three-way fight set inside an atomic power station. You will be assigned one of three roles — Security Guard, Engineer, or Arsonist — and your goal depends entirely on which side you land on.

The three roles and what they want
Table
Up to eighteen players share one room, and the game assigns each of them a role at the start. Because the sides are directly opposed, understanding all three — even the ones you are not playing — helps you read what is happening around you.
| Security Guard | protect Engineers by finding and eliminating Arsonists on sight |
| Engineer | keep the reactor and its systems running for as long as possible |
| Arsonist | create as much chaos as possible and ultimately cause a reactor meltdown |

Glossary
Glossary- Reactor
- The central structure in the facility — Engineers keep it running, Arsonists work to destroy it.
- Interaction
- Any action an Engineer takes on the reactor or a connected system, which triggers a roughly twenty-second period of vulnerability.
- Vulnerable state
- The short window after an Engineer interacts with something during which an Arsonist can eliminate them.
- Meltdown
- The Arsonist's ultimate goal — pushing the reactor to catastrophic failure.
Common questions
FAQHow many players can be in one room?
A single room holds up to eighteen players.
Can an Engineer be killed at any time?
No — Engineers are invincible by default. The danger comes right after they interact with a system or panel, which makes them vulnerable for around twenty seconds.
What should I do if I see someone exploiting?
Capture a recording or screenshot of the behavior, then report it in the game's communications server.
Is the reactor design based on a real one?
The reactor is loosely modeled on the RBMK reactor design, but it is not a precise recreation. The game prioritizes style over strict realism.
