Bingo, that's the thing.
"what the complete, unabridged, 4k ultra HD fuck with bonus features" - Mark Von Lewis

I recall playing a Play Station 1 game about submarine warfare that was set on Earth after a cataclysmic flood (you could find ruins of modern cities on the bottom in some places. Your submarine was upgradeable, and one of the weapons was a guided missile that launched upwards and dropped on the target from above the water surface. IIRC, the ending somehow caused the sea levels to drop again, leaving your sub stranded on top of a ruined skyscraper.
