In this adventure, you will find a city destroyed by zombies and radiation. You won't be able to leave your bunker, so you won't have any choice but to find a way to survive the catastrophe. At the start of the game, you will have some unused rooms and four survivors who will help you start the maintenance tasks and gathering of resources. To be able to convert your bunker in an underground stronghold, you will have to have a good attack, defense and exploration, so try to manage your inhabitants and resources well.
The city you are in is divided into areas that you will have to visit. Large numbers of zombies live in each area, and you must defeat them if you want to get the resources that remain. As well as sending in a strong team that can face the zombie attacks, you will have to make sure that the exploiters are ready to resist the radiation. To be able to leave the bunker and survive different problems, you will be left with no choice but to get enough equipment to not fall prey to the radiation and take damage from the zombies.
Each one of the residents in your bunker will have certain skills and characteristics that will be of great help when faced with specific tasks. Your task as the person in charge of the stronghold will be to find the balance between them all and be able to keep everyone fed without the base falling. Stop the zombie attacks and protect the bunker from any assault as you open the doors to the last survivors and take all the resources you need to survive.
