Underworld : The Shelter (MOD, Unlimited Lives)

Underworld: The Shelter – an economic strategy game with elements of role-based development and mechanics of a city-planning simulator centered around the development of an underground shelter that appeared at the moment when an atomic explosion thundered on the surface of the Earth. Those who survived the catastrophe began to restore civilization: they produce raw materials and produce fuel, look for a vaccine, and fight radiation. They also periodically get out to the surface and explore dilapidated cities, hoping to find new settlers.
The world in Underworld: The Shelter is harsh: if you hesitate, opponents will overwhelm you. And if you make a mistake in the chosen tactics of action, then there is a high probability of encountering mutations, infections, or intolerable hunger.
