Experience Tower Defense Redefined. Orbit is a space-based TD game unlike anything you’ve seen in the genre before. You must protect your planet from incoming alien attacks by sending Satellites into orbit to fight them off. Features game-play infused with Real Time Strategy mechanics. You can freely Move or Swap your Satellites around the planet and Manually Target Aliens with your Satellites to exploit their weaknesses. The entire experience is complemented by a dynamic difficulty curve which responds to your play style in real time to always keep you engaged. This is a game of skill and strategy, not luck or one-upmanship. The more you play, the better you get to understand the strengths and weaknesses of all the game’s unique Satellites and Aliens.
