Concurrent Steam players, not daily or monthly active users. Console and other launchers are excluded. Peaks cover GaugeDB’s recorded history.
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.
