Under the Ice is a submarine warfare video game for the Atari ST and IBM PC compatibles running GEM.

The game takes place in an analog of the GIUK gap, with Iceland roughly centered in the upper half of the map.

Three sections of the lower display allow the user to select and activate the various sensors, fire weapons, and launch acoustic decoys.

Their main concerns were "the paucity of documentation and the resulting slow learning curve" due to the manual not explaining many of the underlying concepts that the player would have to discover through trial and error.

More of his concern was aimed at the game's interface, noting the annoyance of needing to delete waypoints in order to change their speed or depth, and how slightly missing a click on an icon will cause an inadvertent zoom.

But his largest complaint was the speed of the display, "If you're used to animation that moves smoothly, or even semi-smoothly, the complete redraw of the screen every two seconds will annoy you.
