About Casualties: Unknown

About this game

Survive a Harsh World 

Each layer brings its own challenges, adapt and descend. 

Simulated Limb and Cardiovascular Systems 

Injuries are unavoidable. You will have to bandage yourself, fight infected wounds, and stabilize blood loss before losing consciousness. Additionally, your mood can greatly affect your chances of survival, too much doom and gloom will make your life harder. 

Craft to Survive 

As a creature capable of reason, using tools will allow you to travel the cavernous layers more efficiently. In case you start bleeding out, the flora will provide great resources to patch yourself up. 

Explore at Your Own Risk 

Previous expeditions have left some good loot behind. But even helpful things can prove to be your death.

Uncover the Truth 

What actually lies at the end of this journey? And what becomes of you if you are to succeed?
