An invading force of unknown origins has breached the outer perimeter.
With nothing but a trail of destruction left in their wake, the odds seem bleak.
Show courage in the face of adversity and do whatever it takes to stop them from advancing.

• Fight to survive for as long as possible in a distant solar system raging with interplanetary war.
• Outmaneuver your enemies and learn their formations to gain the upper hand in combat.
• Defeat your foes, each with three iterations: Standard, Enhanced and Elite.
• At the end of each cycle, five unique bosses await for you to challenge them.
• Once the fifth boss has been defeated, the elite cycle will begin.
• The elite cycle consists only of elite enemies and multiple bosses will appear at the same time.
