About the Game

Welcome to Sanguis OS.

You are the sole operator of the Leviathan, a massive, blood-fueled drilling machine designed to harvest the energy of the underworld. Your mission is simple but suicidal: descend through the 9 layers of Hell, keep the engine running, and survive.

You cannot see the outside world. Your only connection to reality is a claustrophobic retro-terminal interface. You must rely on your radar, cameras, and resource readouts to make life-or-death decisions.

Key Features:

  • Micro-Manage Survival: Balance your blood (fuel), engine heat, and hull integrity. If you run out of blood, you fall into the abyss. If the engine overheats, you burn.

  • The Venting Dilemma: To cool down the overheated engine, you must open the vents. But opening the vents allows the horrors of Hell to breach your hull. Neutralize threats before they destroy your armor.

  • Demonic Malware: The energy of Hell corrupts digital systems. Fight off demonic viruses like Gluttony (drains your RAM), Illusion (creates fake error pop-ups), and Scramble (mixes up your controls).

  • Harvest the Damned: Blood running low? Activate the crushers to harvest demons and keep the pump flowing.

  • Deep Descent: Descend from Limbo down to the 9th Circle: Treachery. Every layer brings new anomalies and aggressive system failures.

Can you maintain the system, or will you become another ghost in the machine?
