1-4 player online co-op. 6-minute shifts in a 1960s nuclear plant. 1 reactor health bar that only ever falls. Sell power to the town, fix everything that breaks, and keep the safety inspector happy. Clock out rich, or push for one more shift.
Minutes to Meltdown
SteamWelcome to Halcyon Energy. The town needs power, the plant needs fixing, and the reactor needs you not to touch anything you shouldn't.


1-4 player online co-op. Weld leaking pipes, tape up live cables, fix broken machines, and drag your friends back to their feet when the plant knocks them flat from one of countless hazards.



Every shift is six minutes. Vote on a contract, then meet the town's power demand before the whistle. Set the reactor to Economy, Rated or Overdrive and live with your choice.



Everything is connected. Everything is breaking. Pipes burst and throw you down corridors. Live cables bite. Pressurized rooms blow the door off whoever opens it. Spills send you sliding, fires spread, and when the supply goes the lights go with it.



The safety inspector walks the plant and writes down everything you did not mop. Every hazard he finds counts against you. Clean up fast, or hope the puddle bot gets there first.


Get paid, then spend it: bots that mop, service and repair, better tools and upgrades for the plant. Clock out rich, or take another contract and push your luck. Contracts have unique modifiers: control rods due for a change, logistics issues, or a safety inspector on site.



Reactor health only ever falls. Push too hard and the plant goes red, the doors fail open and the klaxon starts. Hit the SCRAM to buy time. If it all goes terribly wrong, you only have Minutes to Meltdown.

Halcyon Energy thanks you for your service.
