Your mission in this great real-time strategy game set in space is to dominate in the space by capturing all the planets. Use YOUR MOUSE to select your blue stars, then click LEFT MOUSE BUTTON to send ships to enemy stars (single click sends half of the ships, double click sends them all). You can specialize the stars using the star type buttons on the top right. I suggest you to play through the tutorial, you will learn more about controls and gameplay. Good luck!
