Escape the Deep · Find H.O.P.E. · Survive
You are sealed inside the Acidbreaker — a research submarine drifting beneath the surface of Planet Cradle of Corrosion, where every ocean is pure nitric acid (HNO₃). The hull is cracking. The coordinates are scrambled. H.O.P.E. is out there — somewhere. You have 60 minutes.
Planet Cradle of Corrosion has no landmass. From pole to pole, an unbroken ocean of concentrated nitric acid (HNO₃) churns under a toxic yellow sky. No vessel survives on the surface for long. Everything of value — the research labs, the escape pods, the truth — was built underground, beneath the acid.
The Acidbreaker is a research submarine, barely larger than a coffin. The walls hum. The screens flicker. The sonar keeps pinging something vast in the dark below. Your job was to find H.O.P.E. and retrieve the evacuation codes. That was before the HNO₃ breached Compartment 3.
Scattered across your vessel's databanks — corrupted navigation charts, encrypted frequency logs, partial coordinates — are the clues left behind by the last crew of the Acidbreaker. They didn't make it out. But they left you a trail. You just have to decode it before the hull gives way.
⚠ WARNING: H.O.P.E. (Hazardous Oxidation Protection Experiment) location is classified. All navigation data has been wiped from this terminal. Crew are advised that HNO₃-ocean pressure at depth exceeds standard hull tolerances. Survival probability at current integrity: 12%. Proceed with all available urgency.
Somewhere in the deep — further than the sonar should reach — a repeating signal has been broadcasting for 312 days. It carries a voice. One sentence, looping. "The way out is written in the pressure." Nobody knows what it means. You have 60 minutes to find out.
You wake inside the submarine. The lights are red. Every screen is throwing errors. You must restore power, decode the nav system, and decipher the last crew's encrypted transmissions to extract the partial coordinates of H.O.P.E. The HNO₃ is rising in the lower deck. Move fast. Think faster.
The coordinates from Room 1 guide you to H.O.P.E. — a submerged research station locked down after a catastrophic event. The escape pod is here, but the launch sequence requires codes hidden across the lab. Something else is here too. The previous researchers left notes. Not all of them made it to the pod.
The pod breaches the acid surface and punches through the atmosphere of Cradle of Corrosion.
Below you, the ocean swallows every trace of the Acidbreaker.
You made it. Against every probability. You made it out.
The acid reached the control deck at 59:47.
The last thing the sonar recorded was a proximity ping — H.O.P.E., only 200 metres away.
You were so close. The ocean of Cradle of Corrosion keeps its secrets.
