About Reactor 13

Reactor 13 is chaotic co-op for 1–4 players. Grab, wash, charge, and craft dark-matter blocks to power everything from a single house to the whole planet. Overcharge for huge gains but watch for the meltdown. Play solo or have someone else to blame.

You and your crew have been assigned to Dark Matter Reactor #13 - the world's brightest hope for powering the entire planet. Dark Matter is powerful, valuable, and deeply unstable. Feed it well and it will light up the world. Push your luck too far and, well… chain reactions are beautiful, but an inefficient way to run a reactor.

Operational guide

Please review the following before your first shift:

•
Collect raw Dark Matter from the intake belt, then wash, charge, and craft it into usable fuel.
•
Feed the reactor to raise output - and watch the wall gauges to steer the reactor to the right balance.
•
Balance fuel and coolant. Heat builds fast, and an overheating reactor is, technically, a resignation and respawn.
•
Run clean and efficient: better input means less heat and a higher score.
•
Overcharge for a bigger payout when you're feeling lucky - just remember what "chain reaction" means.
•
The higher the output, the harder the balance. Powering a house is simple. Powering a planet is not.

Key Features

•
Frantic local co-op reactor blame fest for 1–4 players.
•
Push your luck - overcharge for big gains, risk a chain-reaction meltdown.
•
No HUD - read the reactor off in-world factory gauges.
•
Climb the power scale, from a single house to the whole planet.
•
Unlock new levels and chase your best power output score.
