Download System Lord
System Lord is a real time strategy game filled with inspirational elements from Stargate, hence the space theme that is present in the game. In the beginning you have a base and around it you must build your small empire and conquer your enemies in order to advance through the campaign.
The defense is the first thing you should take care of and if you want resources you should start working to create cargo ships that transport materials to your base. As long as you have resources you will be able to create a powerful army that will conquer the whole solar system.
