CTRLSINK
SteamCTRLSINK is a submerged post-apocalyptic retro-style FPS set after a devastating human/AI war. The world has drowned, the continents swallowed by rising oceans, and the last traces of humanity lie scattered in flooded bunkers and rusted war ruins. Blast through radioactive facilities, fight corrupted machines, and uncover the final secrets left beneath the waves.

Deep beneath the Antarctic ice lies SUBY --> an analog submarine fortress buried far below radiation zones, forgotten by the wars above. Inside it rests the last preserved humans, sleeping in cryogenic chambers for 333 years, untouched by digital influence.
SUBY is fully analog. No uplink. No signal. Only silence --> until now.

After centuries of isolation, Protocol CTRL has begun: the gradual awakening of the crew. Each revived human is immediately bonded to an Extreme Human Armor Suit, a relic of the pre-war era --> no AI, purely biological-mechanical and analogical systems. It heals. It strengthens. It protects. Is Controls. It is the only thing keeping humanity alive outside SUBY’s hull.

Every awakened person becomes a new Crew Unit, sent to gather data about the fallen world, discover what truly ended civilization, and search for any land still capable of sustaining life.
The mission codename: CTRL/SINK.

--> CTRL your situation or SINK One human at a time. One last chance for the species. If a Crew Unit dies… the next cryo pod opens.

You are Unit N94. Two before you, N92 and N93, left SUBY and never returned.
Your first task: find their traces. Your real task: survive what took them.

Venture into hostile radioactive complexes built by machines that outlived their masters. Expect brutal, fast-paced combat, analog weapons, corrupted AI guardians, robots cyborgs, and a world where every corner hides a threat or a forgotten truth where he ocean swallowed a large part of the world after the polar ice melted during the nuclear wars. Fight to CTRL… but don’t SINK.
