Coldroom

Take control of a refrigerated warehouse where every door opening, cooling adjustment and crate placement changes the thermal balance. Route cargo into the right temperature zones, tune compressor power and bay valves, dispatch stable inventory and react to sensor drift, defrost cycles, grid dips, blackouts and frost buildup. Progress through 25 handcrafted tasks across five chapters, earn credits only by playing, and install workshop upgrades that directly improve cooling, insulation, equipment health, backup capacity and inventory handling. Coldroom is fully offline with no ads, purchases, accounts or waiting timers.
