Choose wisely when equipping your ship with weapons and defenses, selecting power-altering modules, or determining the optimal combination of shards to use. The distinction between optimal and sub-optimal choices can significantly impact your progress. But while there are a lot of decisions to be made, they are all plainly understandable so that the optimum, or at least very near optimum decision making is within your grasp!
Well paced progression combined with the amount of different systems, upgrades and enemies, means something new is frequently just around the corner.
