CAPTAIN SONAR: OPERATION DRAGON

* In search of rare minerals, the crews dive to never-before-seen depths where the laws of physics reach their limits. In the "Operation Dragon" campaign mode, teams can play seven consecutive missions on ever-new nautical charts, using expert characters with abilities exclusive to them to make it through this adventure. The result of each game affects the next mission...

* The "Custom Pack" toolbox contains four new modules with new options to vary your gaming experience, such as "Armada" mode, new second stations, and new mechanics stations.

For playing you need Captain Sonar.
