About This App

Build your own power company from the ground up. Manage heat, optimize production, and grow a massive energy empire. In Reactor 2, you don't just construct power plants — you power an entire evolving city.
Master the system, discover your best strategy, and scale your profits to become a true industrial billionaire.
⚡ BUILD, POWER, AND EXPAND
Start small with basic wind turbines and grow into a high-efficiency nuclear power network.
Your mission is simple — supply energy to the city. Your challenge? Control the heat.
