A post-apocalyptic economic strategy in which the player is tasked with managing a small society living in a fallout shelter. The world in Life in Bunker is procedurally generated and player has access to four underground floors. Thanks to that, as the game progress, the bunker can be expanded not only horizontally, but vertically as well. The people living inside the facility represent one of six professions and have individual character traits. The main task of the player is to efficiently manage resources such as food, water, energy, clear air, garbage, metals or building materials. In addition to bunker expansion, one must also systematically develop new technologies. A system of random events makes the game more unpredictable. It can cause diseases, infections, power outages, and various other emergencies.
