Prisoner of Ice

Prisoner of Ice (also Call of Cthulhu: Prisoner of Ice) is an adventure game developed and released by Infogrames for the PC and Macintosh computers in 1995 in America and Europe. It is based on H. P. Lovecraft's Cthulhu Mythos, particularly At the Mountains of Madness, and is a follow-up to Infogrames' earlier Shadow of the Comet. In 1997, the game was released on Sega Saturn and PlayStation exclusively in Japan.

Plot

Prisoner of Ice begins during the run-up to World War II, primarily around Antarctica. The main character is a young U.S. intelligence officer, Lt. Ryan, who has been assigned to a British submarine, the HMS Victoria, for a special mission. As the game begins, the submarine is fleeing the Antarctic after rescuing a Norwegian who has recently escaped from a secret German base in the Antarctic (it is later revealed that the base is built atop the Ancient Ruins mentioned in At the Mountains of Madness). Along with the Norwegian, the sub has picked up two mysterious cargo crates stolen from the Nazis.
