The game was ported to MS-DOS compatible operating systems and published in 1995 by Dinamic Multimedia.
A U-92 submarine takes Derdhal outside the arctic base and he must use his weapons and skills to finally find out what is going on.
In the first part, the player fights with hordes of various enemies varying from arctic commandos to air troops, who will shoot or throw grenades instantly.
Not only must the player defend the energy bar, but they must also watch the limited time offered before ending the mission.
There are a few huge beasts called CAPITOSAURUS, some of them throwing acid balls, which can only be killed by grenades.
