Reactor 13

Reactor 13 is chaotic local co-op for 1–4 players. Grab, wash, charge, and craft Dark Matter blocks to power everything from one house up to a whole planet. Overcharge for huge output; the chain reactions are half the fun, the meltdown is not. Play solo or have someone else to blame.

Wash the Dark Matter

Dirty ore hides its color. You cannot craft blocks you cannot tell apart.

Craft it, then craft it again

Craft same-color blocks into something better. Then do it again. Each color does a different job in the reactor.

The reactor does not feed itself

Wash, charge, craft, feed. Split the work across the crew, or run it all yourself.

Push it too far

Chain reactions may blow up all your blocks, or none of them. Always someone's fault.

Key Features

• Local co-op for 1–4 players on one screen. Single player works too.
• Keep every job running: wash, charge, craft, feed.
• Craft same-color blocks into better ones. Each step raises output more than the last.
• Charge any block for more output. Overcharge past the safe limit and it may set off the next one, and the next, or nothing at all.
• Red is fuel: more speed, more heat. Blue is coolant and brings the heat back down. Green cuts friction, so the reactor runs cooler and produces more.
• No HUD. The gauges on the wall are the only instruments in the building.
• Output is the score. The higher you climb, the harder the balance. A meltdown ends the run for everyone.
