Chaos tower

This tower slows down enemies within it's range, but unfortunately amp towers cannot increase that range. Research of the blocking tower is required first, but it is the cheapest research in savage moon. It may cause you a headache though that chaos towers have to be researched for 250 resources. Chaos towers slow down enemies rather greatly but the short range and high cost mean it is by no means an essential tower. If you desire to have one, it is best placed near a strong battery of towers and where enemies will spend a relatively long time going near it.
