At the height of urban civilisation, Thea’s sprawling mega-cities stood as monuments to human achievement. Then came the Darkness — a cataclysm that shattered society, claimed billions of lives, and left the world in ruin. In the chaos, a secret network of underground shelters became the last refuge for the few who survived.

Project Thea, the final remnant of the Ostoya mega-city, now stands as sentient-kind’s last hope. As its sole guardian, you must venture into the treacherous Wastelands to scavenge vital resources, confront roaming threats, and guide the Project’s growth. Every decision counts — for if the Project falls, civilisation will fall with it.
