Colony Siege

Colony Siege is a sci-fi real-time strategy game with tower defense elements and an isometric camera view. The events of the game take place in the distant future, when humanity has begun to explore the universe in full swing, simultaneously creating numerous colonies. But with the discovery of something new, alien races came who did not really like the activity of humanity. Now you have to defend the colonies and fight the hordes of Xenos and the Rift. As you progress, you will be engaged in arranging the base, building robots for protection, and will be able to fight opponents with a friend in co-op mode.
