Up Periscope!

Up Periscope! from 1988 lets you take command of a submarine, which sounds exciting until you realize just how much responsibility that entails. Managing depth, speed, and positioning requires constant attention, and mistakes can be costly. The gameplay is deliberate, encouraging careful planning rather than reckless action. There’s a tension that builds as you navigate dangerous waters, never quite sure what’s lurking nearby. It’s not the fastest-paced experience, but it captures the feeling of underwater warfare in a way that’s both engaging and occasionally nerve-wracking.
