Such an amaizing game.
Usually i would get tired to space shooters like this, mainly because they become repetetive and have no story in them, however.. this one differs from the majority. It actually has a very good story.
The gameplay never becomes repetitive due to the upgrades, variety of enemy ships and somewhat increasing difficulty. About the difficulty, it is really good. You aren't instantly some super-hero who can destroy anyone.. you have to build into it. Spend some time and explore the universe.
Thank you for this magnificent game.
