A submerged post-apocalyptic retro-style FPS set in a world swallowed by the ocean after a human/AI war. Blast through flooded facilities, battle corrupted machines, explore radioactive ruins, and uncover the last buried secrets of humanity’s collapse.

CTRLSINK 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.<video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4209430/extras/a9b682e718ab187cef8c10a7e7063278.poster.avif?t=1770259992" width=600 height=338 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4209430/extras/a9b682e718ab187cef8c10a7e7063278.webm?t=1770259992" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4209430/extras/a9b682e718ab187cef8c10a7e7063278.mp4?t=1770259992" type="video/mp4"></video>Deep beneath the Antarctic ice lies SUBY --&gt; an analog submarine fortress buried far below radiation zones, forgotten by the wars above.
