CIX is an evolution of the defense game genre. Your goal in the game is to build allies to defend three colonies from hoards of enemies.
Click and hold to open the Build Menu. Build X-Systems. Then click and hold next to the X-Systems to build guns, sensors, wings, thrusters and other systems onto the X-Systems. Adding a thruster to the Ally will lift it off the ground and allow it to fly around searching for aerial enemies! Experiment with making the coolest Allies!
