Pay to win. 1 star until they fix the way to get blueprints. The only way to do so is with class battles. And on every category you get paired against special ships. So you cant compete because they are way overpower vs regular ships. They got to many extra slots so they can gear plenty more weapons and beat you. And the only way to get galaxies to get the blueprints of those ships is winning those battles. Impossible. Just pay to buy them and you can ha e some fun.
