You will gain access to the military space base, where you can take a fighter jet and fly. First, you need to pay the redistributed amount of money and you have it. You won't have enough for anything else. Get on the fly and by completing missions you can earn coins. Objectives will most often consist in destroying enemies and flying over enemy territories, where you will inevitably face the enemy. The reward received will allow you to improve your aircraft. You can change the engine to a more powerful one, strengthen your armor, change weapons or add a new one, put shields. All this will be needed when completing the next mission. Later, you can even purchase a new aircraft with improved technical parameters in Fractal Combat X.
