You fell through. Now you're trapped in miles of flooded tunnels beneath the city with one lantern and something hunting you in the black water.

This is a true open-world survival RPG. No set story. You inhabit the world. You can die. You can do whatever you want.

HARDCORE SURVIVAL — Light is finite. Noise brings it. Water is rising. Cold kills. Combat is brutal. Wounds matter. The monster cannot be killed easily, it herds you.

3 GREETINGS:

1. ALONE — Solo survival, you wake up in black water

2. ALLIES — Bring anyone you want (friends, family, dog, crew) — you define them

3. YOUR SCENARIO — You set your own story, gear, and starting point
