Your submarine is trapped under the sea by icebergs. It needs to reach the surface of the water withput crashing into the icebergs.

Your mission is to fire torpedos at the icebergs to destroy them - you need to declare war on the icebergs! Once all icebergs have been destroyed, the submarine can then safely get to the surface of the water.+

Using tactics and accuracy, fire torpedoes to destroy icebergs and clear the way for the submarine to surface.

Torpedoes are fired by tapping the screen.

The game details will be saved at the end of each completed level (provided that the submarine hasn't crashed, or the game hasn't ended), so that players can resume from the beginning of the next level.

The submarine gets faster as the levels progress.

There are several dozen different iceberg landscapes.
