Upgrades

Upgrades improve a ship’s combat characteristics. The number of available upgrades and slots depends on the warship type and tier. To view and mount upgrades for the selected ship, go to the MODULES tab.

Upgrades and thoughtfully selected Commander Skills can noticeably improve certain parameters of a ship and enhance her battle performance. For example, with the "Damage Control System 2" upgrade and a Commander with the "Basics of Survivability" skill, the time to extinguish fires will decrease considerably and players don’t even have to use Damage Control Party.

Upgrades can only be demounted with doubloons, so study their characteristics thoroughly before installation.
