BunkerSIM Update #1!
PAX East, moving to Unity
Humanity is at a low point. Nuclear war destroyed everything. Anything not touched directly by a blast is now covered in radioactive dust and dead. You are a survivalist, an expert in survival. You went as far as giving classes, but most people called you paranoid; especially for building that fallout shelter in your backyard. From it, you will expand and create a safe haven for survivors and travelers of the wasteland.

Once you’ve taken control of your home region, you will fight bandits and establish other shelters around the country. Just like resilient little rats, the last members of humanity now live underground and are hoping for salvation. It is time to seize the day and bring it to them!

Survive & Expand
Bunker Sim is all about building a fallout shelter underground, ideally making it self-sustainable. Dig, build, research, craft, expand and explore! Bandits, merchants and beggars will knock at your door.

Every inhabitant of your bunker is simulated! Inspired by the pyramid of needs, all decisions are based on many factors. We worked hard to find the best compromise between fun and depth. A friendly alert system and daily reports provide a look at your inhabitants.

Craft or find clothes and items for your characters. Manage their self-improvement goals and job to create the most efficient society.

Gear up and roll out! Gamble your life and resources to explore the wasteland. You might find loot, but watch out for the bandits roaming around.
