SURVIVE THE CRUSHING DARK
Build your colony on the ocean floor. Pilot submarines into the unknown. Keep your people alive in the deepest place on Earth.
Salvagers - Scrapper, starter hull
"The sun entered its death throes centuries ago. Billions fled underground. Underwater. The wealthy fled to the stars."
You command a fragile underwater colony. Manage your crew, expand your base, research new technology, and send submarines into the dark to find what others left behind.
Nobody knows what happened to the Ascent - the ships that left Earth.
Every faction starts with one hull and researches two more. Refit in a hangar, crew it, and send it where no one else dares.
Three mismatched boiler sections riveted into one stubborn hull. The colony's first sub.
A salvage tug turned sub, with tyre fenders and a hydraulic grab claw. Slower, tougher, hauls harder.
A scrapped fishing trawler welded shut under a riveted lid. Nets and a deep hold bring more home.
A glass sphere on a clean steel tail. The expedition's survey sub.
A buoyancy float over a crew gondola, rated for crushing depths. Slow, but hard to breach.
A long survey hull with a glass brow and a sonar dome under the chin. The fastest sub in the deep.
A wedge of bolted armour plates with a ram on the bow. Built to endure.
An ironclad raft under an overhanging armour deck, one big turret drum. The toughest hull, and slow.
A domed carapace of overlapping plates with a ballast pontoon down the side. Slowest and roomiest.
Station systems
Every room has its own stations, and every colonist works them by hand: pulling levers, turning valves, tending crops, treating the sick.
Harnesses geothermal vents to generate electrical power. The beating heart of the colony. Must be built near thermal sources.
A cluttered workspace of salvaged instruments, specimen tanks, and flickering screens. Here, the desperate science of survival happens.
A cluttered workspace for fabricating parts, repairing equipment, and turning scrap into something useful. Smells like oil and desperation.
Medical facility that heals injured inhabitants. Staff accelerate recovery. Adjacent to Quarters grants resting health bonus.
Cramped living quarters carved from rock or welded from salvage. Not comfortable, but it keeps the pressure out and the nightmares in.
Recreation facility providing morale boost. No staff required. Adjacent to Quarters enhances rest recovery and morale.
High-temperature foundry that converts scrap into refined steel and glass. Adjacent to Workshop boosts both rooms.
A bare-metal vertical shaft with welded rungs. Slow but reliable. Can be sealed to isolate flooded floors.
Advanced growing facility that converts water into food and bioplastic. Requires staffing to maintain optimal yield.
Hover a room or a row to inspect it.
Place and connect rooms on the seabed grid. Power plants, med bays, smelteries, labs - each one vital.
Assign colonists by specialty. They sleep, eat, fall sick and get back to work.
Oxygen, water, food, power - everything is finite. Balance production or watch the lights go out.
Send expeditions into the dark. Derelict vessels, sealed vaults and things that should have stayed asleep. Every encounter is a choice with real consequences.
Hullgrave is in active development. Wishlist on Steam to follow the journey.
