Level 13

Level 13 will immerse you in a gloomy underground city where humanity struggles to survive among ruins and eternal darkness. You begin with a broken leg and only the barest supplies. Your goal is to set up camp, explore abandoned sectors, and gather resources to regain your strength and ultimately find the way back to the surface.

You’ll need to manage scarce reserves of water, food, and stamina. Build shelters, defend yourself against mutants and machines, and uncover technologies that may bring back hope. Every choice you make shapes your survival—from desperate scavenging in dark tunnels to carefully planned settlement growth.

This is a story of hunger, fear, and relentless time. Can you endure the chaos and find the path to the light?

Note: The game interface is fully accessible with screen readers. For additional information, such as item or resource descriptions, use the keyboard. Move focus to the desired element, then apply the “move mouse pointer to current object” command to hear the contents of the pop-up window, navigating it with the down arrow. The game also uses environmental sounds to help you stay oriented in the world.
