This Upgrade 2 expansion lets you dive deeper into Captain Sonar’s immersive experience.

There are two upgrades that can only be used in real time mode.

The “Operation Dragon” campaign brings you on an thrilling adventure to discover unexplored seas. You may play the scenarios in this campaign separately, or in any order you want. But to get the best experience of this campaign we recommend playing the scenarios in order, and with the same crews. This campaign offers an experience system in the form of Expert Cards. These characters will be able to assist you occasionally, throughout the game. The second part of Upgrade 2 is the Custom Pack, a toolbox that can be utilized on all the maps that have been published to date. This toolbox lets you adapt the game to your liking: “Armada” mode, new First Mate stations, new Engineer stations... there’s something for everyone.
