League of Chaos is a sci-fi side-scrolling strategy game. Choose a territory on the map to start a battle. Each battle has you controlling a hero, building structures, and sending out units as you battle incoming enemies on multiple paths. There is a limit to how many units you can have on the screen, but this limit can be increased by building houses. Building structures and training units will cost you crystals, which are produced by mining towers. Destroy your enemy's base to win the battle and conquer the territory. After each battle, you can upgrade your offensive and defensive skills.
