Broken Universe Tower Defense — your citadel must be tightly defended so that no enemy can get there. To do this, you can improve buildings, improve them and make them even more durable and powerful. Each such building has superpowers and its own unique elements. For example, one tower only shoots at ground creatures, while the other can destroy both. One tower fires exploding shells, and the other traced, the third freezes opponents, and the fourth burns. And there are a lot of similar innovations here. Set up barriers, set up traps, build a bunch of towers that will protect you. You have only one goal to defend the citadel from opponents trying to break through there.
