Sins of a Solar Empire II/Oceanic planet

Oceanic planets are a rare type of colonizable planet encountered, and offer 0-2 metal asteroids and 0-2 crystal asteroids. They are roughly equivalent to Terran worlds in terms of their colonization power, but require some research to make the most out of.

Oceanic planets require the Oceanic Development research item in order to be upgraded past level 13.
