QSERF, standing for Quantum Science Energy Research Facility, is Quantum Science's current flagship game. It is currently going through a revamp of all the sublevels.
The Dark Matter Reactor is Quantum Science's largest innovation. It uses nuclear fusion injected with dark matter to create up to 500 GWh of power.
No matter how well the facility is built, maintenance is always required. These are some of the maintenance tasks that can be done in QSERF.
