How did I create the game?

After the huge success CAPTAIN SONAR, my friend, the Lieutenant Yohan and I wanted to enhanced the universe of the game.

The core game is already very rich and massively replayable, but with this expansion, tactic options are even greater.

The minds of the captains will reach the boiling temperature ! And never forget that at the bottom of the ocean, no one will hear you scream !
