CIX is an evolution of the defence game genre. Your goal in the game is to build allies to defend three colonies from hoards of enemies.

Instructions:
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!
