MISERY is a hardcore engineering simulator where you manage an underground colony after a global extinction event. There are no zombies here. There are only wiring, logistics, and complex resource management. Cold start The first 60 seconds are an introduction to mechanics: what will you take to launch your autonomous base? Chemical reagents? Solar modules? Robotic tools? After the explosion, the real work begins: design, installation, calculations. Chaos is left outside. Your goal is to build a self-sustaining survival mechanism. Rooms, generators, ventilation, temperature control, AI modules. No mysticism, just pure engineering. But even here, resource assumptions cost you mistakes. If you don't optimize, it burns out. If you run an extra cable, it's out of balance. Here, victory is efficiency. Game features Accurate modeling of underground life support systems. Step-by-step design with calculation of load, heat and consumption. Deep tech design: from generator types to power supply routes. Complete autonomy is the ideal. A flaw in the design is the end result.
