GAME OVERVIEW
Welcome to Nuclear Reactor Simulator. Here, you’re the one in charge—a nuclear plant operator managing one of the toughest, most dangerous systems out there. You’ve got your AI assistant, AO, for backup as you juggle reactor output, keep things running smoothly, and try to steer clear of disaster.
This isn’t some casual game. It’s a true-to-life simulation designed to push your strategy, your concentration, and your ability to make quick decisions when things get real.
You get to manage more than 200 parameters and deal with 150 switches across the crucial parts of the plant. From the Control Room to the Cooling Towers, every spot matters. Xenonauts 2

Doesn’t matter if you’re a veteran or completely new to the world of reactors—it delivers a wild mix of adrenaline and learning.
It’s all about balance. Keep a close eye on reactor power, coolant flow, and steam production to maintain stability. But you never really get to relax—fires, floods, and equipment failures can hit any time.
The AO assistant has your back with startups, alarms, and crisis control. You can upgrade it as you go, and every update means smarter support.
Every day brings tasks—complete them to earn Prestige and XP. You’ll need to keep an eye on fuel, costs, and what the public expects. Put your rewards to good use with upgrades, better safety gear, and smarter ways to manage radioactive waste.
The environments are realistic and the gameplay keeps evolving, so there’s never a dull moment. You won’t get coddled—every playthrough is a fresh challenge. Dive in, take command, and see if you’ve got what it takes to keep the lights on… or risk everything in a meltdown.
